    Imaged with my AG12 and H35. A massive task to tame Alnitak, it took over 12hours to process this one. Exposure times were 4x900s in H-alpha, 4x900s in Red, 4x820s in Blue and 4x640s in Green. Processed in Photoshop and Lightroom. Comments welcome thanks for looking

    I'm still dizzy after processing this one for each LRGB filter. Comet 21P meets open cluster M37 in the night/morning of 10/11 September, at perihelion. This is a combination of 60s x 30 x 4 subs, taken through the SW130PDS with an ASI1600MMC. https://www.astrobin.com/366252/ No deconvolution applied, only noise reduction. About the remaining noise?! ... yes, please. Unfortunately the light pollution at home didn't let me record more. Thanks for watching and clear skies! Alex

    First one of the year, folks. We've had a cracking run of skies and I did this over the last four nights in what's now the single Tak 106, since Tom's camera has moved next door to his new robotic shed. Mesu 200/Atik 11000/Baader filters. Luminance 20x15mns, RGB 9x10mns per colour, Ha 13x20 mns. Total just short of 14 hours. This target is beset by challenges. There is a veritable air display of satellites in this region, each sub copping four or five. Then there were off shot flares blazing across two parts of the image. We had great seeing for the first two nights but then set two new world records for bad seeing after that. Never seen anything like it. FWHM went from 0.88 on night 2 to 2.3 on night 3! Fortunately I got the L on the first two nights so soft colour wasn't too hard to deal with and there is no fine detail in the Ha. (The Ha gives the image a real lift but is incredibly faint. Had anyone seen what I had to do to get it into the image they'd have notified the Police.) Anyway, enough excuses. Here she is... Olly

    Well, I couldn't find another image of NGC4157 on SGL so it's obviously not that popular a target ! The galaxy is located in Ursa Major about 56million light years from Earth and is approximately the same size as our own Milky Way. It is receding from us at 774 km/s. From Earth you see it almost edge on, however, a little of the core detail is visible. Three supernova explosions have been recorded in this galaxy. Processing this galaxy was less than straightforward due to the fact that it has a low surface brightness but it is also surrounded by bright blue stars. The LRGB image below represents 14.5 hours integration time and was taken with my Esprit 150. I've also attached an annotated version for the background galaxy fuzzy hunters. I hope you like it !

    Finally, half a clear night and I had my second chance to learn to master the Mesu mount. Put the Esprit 150 on it with the ASI 071MC at the camera end (gain 200, offset 30, -15°C). After a bit of fighting with the software running the mount (I thought I remembered how to do it but had finally to read the manual again), I started imaging at 21.30. At midnight clouds moved in so I only got 2.4 hours of data (29 x 5 min). Still, I caught a lot of galaxies, the three larger ones being NGC 4725, 4712 and 4747. Seeing was probably relatively poor since I was far from the Mesu guiding curves people post. Mine was around 1.0" RMS. Stacked and annotated in PI, processed in PS. It may be clear on Monday night and my plan right now is to collect lum using the Esprit 150 with a 0.79x TS reducer (so f/5.5) and my ASI 1600MM. Will give a very similar FOV and pixel scale. Comments and suggestions wecome of course!

    Rogelio Bernal Andreo pointed this one out: patches of dust near the Black Eye Galaxy (M64). I found this one quite difficult to process and I'm still not sure if I'm happy with the colours... There's a large difference in brightness between M64 and the lane of dust. Usually I try to keep away from local brightness adjustments, but this time I had to process M64 separately, because otherwise it would be completely overexposed. Captured last weekend from Grandpré (Ardennes, Northern France). Total integration time of 5 hours and 40 minutes. 5 minutes subs @ ISO 400. Takahashi Epsilon-180ED and Nikon D810a.

    Greetings! Today I will be sharing with you all, the coolest galaxy in the night sky: Messier 51- The Whirlpool Galaxy. I gathered a total of 17 hours of data (14hrs Lum, 3hrs RGB) under bortle 4.5 skies. This was a very quick process with the RGB but the color turned out exactly as I wanted it to. I may re process this again but I’m extremely happy with these results! This wasn’t supposed to be a project until late March or April but I just couldn’t help myself?. Hope you all enjoy one of our galactic neighbors Equipment: Astro-Tech 8rc (.82pix/") CEM60 gem Atik 414ex monochrome ccd QHY5L-ii autoguider Astrodon LRGB

    The Headphones Nebula This project has tested me beyond all imagination. With much help from folk on here, I finally managed to get the EdgeHD 8" collimated, back spaced and functioning as well as possible. The weather has done everything it can to scupper me - I had a small snowy flood in the observatory and the QSI doesn't seem to like very cold ambient temperatures. Processing of the data has been a huge challenge. I have a fair bit of data, but this target is extremely faint, so I just don't have enough data to combat the noise. The image reminds me slightly of an impressionist painting, but hey, they can be quite nice! The target itself is an old planetary nebula some 1,600 light years away in the constellation of Lynx. It has the catalogue numbers of Jones-Emberson 1 and PK 164+31.1. It is only magnitude +14 or +15, sources vary, and given that it stretches across about 3 light years, it has a very low surface brightness. This thing is faint! The white dwarf star that remains after the explosion that created this nebula is clearly visible in the centre of the nebula and is extremely blue, almost turquoise, shining at just magnitude +17. Is this the ultimate fate of our own Sun? Something like this anyway and we certainly won't be around to witness it... by we I mean humanity! Technical Details Celestron EdgeHD 8" with 0.7x Reducer, QSI 683-WSG8, Astrodon 31mm filters, Mesu 200. Ha = 18 x 1800s OIII = 20 x 1800s RGB = 24 x 300s each TOTAL = 25 hours I could have done with a load more data really given how faint the target is and how slow my SCT is, but the Sky Gods have decided otherwise. It doesn't look like there will be any good imaging nights before the Moon comes back, so that is it for this project for now. I have done my best with the data I collected and am happy to let this one go now. I can't face any more time trying to tweak this and desperately trying to stop it being noisy. Damn headphones... Hope you like it and please do let me know what you think. Clear skies!

    Like the lunatic that I am, I decided to get the scope out last week during that storm that was passing through. The skies were clear and there was no moon about, so I figured why not! Only problem was the 17-20 mph winds, lol. I got 2 hrs of subs but had to throw away half of them due to guiding problems more so than the wind, amazingly. This was the 2nd time in a row i'd had Dec guiding problems, and that's after about 2 years of not having a single problem guiding. After the 1st hr of wasted subs, I turned off Fast Switching in Dec and chose to only Dither in RA, and the Dec problems mostly went away, at least to allow me to capture 1 hr of 'still dodgy but just about useable' subs. Once M42 disappeared behind the neighbour's roof, I then re-calibrated on the Celestial Equator (Dec 0) and when I switched to the Pinwheel Galaxy I was able to guide as normal again (with Fast Switching and Dithering in both RA and Dec both turned on again) and didn't lose any subs, despite the wind, so I've decided that from now on I won't be calibrating at the target itself, i'm always going to do it at Dec 0. I decided to throw this in with another 1 hr of subs (plus 10 x 30s for the core) that I took back in Jan 2017 (has it really been that long?!). That hr also had issues, with some weird streaking in the lower left that I could never work out what caused it. The D5300 hadn't been modified at that stage either. So I fired it all in to APP and decided to stack it anyway, and give it a quick process. Then chose to crank it up to 11 on the colour front, just for laughs. It won't be going on the wall anytime soon, lol, but I suppose it came out a bit better than I was expecting, all things considered. 20 x 360s with an IDAS-D1 D5300, 80ED, HEQ5-Pro. Stacked in APP, processed in PS. CS! edit - I forgot to downscale it - so no pixel peeping allowed ?

    Ive wanted to get a nice rendition of Orion for ages but its one I always overlook as sky time is very precious in the UK and there is always something else to get. Its got to be the most imaged target in the sky but is it easy....I dont think so. The colour and tonal range is massive making it a huge task to process. It took me around 12hours to process this one. Imaged in one night with my AG12 F3.8 Newt and Starlight Xpress H35, conditions were variable with light haze hindering the session, but to be honest I'll take what I can. We have had another very poor winter season with partial clear skies and rain as most of you already know. Exposure times were. 4x900 Ha 1x900 in R 4x840 in B 4x620 in G. Core exposures in RGB were 30s. Managed to increase the red signal with the H-alpha frames. Not Ideal but it is what it is! Calibrated with DSS, processed in Photoshop CS3 and Lightroom. thanks for looking

    From Wikipedia: "The Cone Nebula is an H II region in the constellation of Monoceros. It was discovered by William Herschel on December 26, 1785, at which time he designated it H V.27. The nebula is located about 830 parsecs or 2,700 light-years away from Earth. The Cone Nebula forms part of the nebulosity surrounding the Christmas Tree Cluster. The designation of NGC 2264 in the New General Catalogue refers to both objects and not the nebula alone. The diffuse Cone Nebula, so named because of its apparent shape, lies in the southern part of NGC 2264, the northern part being the magnitude-3.9 Christmas Tree Cluster. It is in the northern part of Monoceros, just north of the midpoint of a line from Procyon to Betelgeuse. The cone's shape comes from a dark absorption nebula consisting of cold molecular hydrogen and dust in front of a faint emission nebula containing hydrogen ionized by S Monocerotis, the brightest star of NGC 2264. The faint nebula is approximately seven light-years long (with an apparent length of 10 arcminutes), and is 2,700 light-years away from Earth." This image has been a delight to process and much simpler than my last image of the 4 panel mosaaic of IC59-63. I do particularly enjoy the wonderful 'texture' of the Fox Fur and the delicate blushing orange/yellow reflection nebula seemingly floating above the Cone. The bright blue stars of course needed some taming and careful care when combining the Ha to avoid excessive ringing.

    I’ve just received a new Altair scope so was keen to give it a try. Unfortunately the forecast was not good for yesterday evening but indicated that skies would magically clear at around 2am... As I didn’t have work today, I decided to set my alarm for 1.30am and look at some early morning targets - which of course meant that some autumn/winter objects would be in the skies in the east. So the alarm went off at 1.30am. I was in a deep sleep so had significant second thoughts about the merits of an observing session. These deepened when I looked outside and saw a blanket of cloud everywhere. I checked the forecast again and it still said clear skies at 2 so I waited for a few minutes and then noticed a small line of beautiful clear sky arriving from the north. I jumped (sort of) into action and went to set up and by 2am, around half the sky was clear. The 72mm mounted on the az gti very well, and two star alignment done quickly. My 55mm plossl with night vision monoculars and Ha filter turned out to be the only eyepiece used through the night. As it was getting close to going behind the house I went straight for a favourite, the North America nebula. The 5 degree fov of the 55mm plossl framed this really well and it was nice and fluffy! I tried the Veil but unfortunately it was already hidden. So onto the early morning objects. I decided to move down the Milky Way gradually starting from zenith down to the east, where I hoped Orion would be visible at around 4am. First stop was IC 1396 which contains the elephant trunk nebula. I’ve found this a tricky target with NV, the nebula looking quite indistinct previously despite its large size. However tonight I managed to get some decent views including the trunk. Then carrying on down to a really nice pair of objects - the heart and soul nebulae. The 5 degree fov just about fitted both objects in, which was a real treat and there was some very nice detail in both. The heart really does look like a heart. I’ve heard the soul described as a foetus and it does have that type of look. Spent a good while looking at these, since this was one of the nicest I’ve seen them. Then getting further on down to the east to an object that’s been a disappointment for me before, the flaming star nebula. I’ve never really got a satisfying view of this - until tonight. Also the neighbouring IC410 was very clear this time. I don’t think it’s still revealing it’s delights completely to me so one to come back to in the months to come... By now it was getting late and darkness would start disappearing soon at 4am, so a quick visit to the California nebula. I had a lot of fun with this DSO earlier in the year and it came good again - I think it likes NV. Really clear, defined and bright. So pack up time and I reflected that it was worth getting up after all. Finally I noticed, that Orion (or at least the top half) was now visible in the east. I took the monoculars off the scope and viewed at 1x. At last, my first ever glimpse of Barnards loop. I could only make out the upper half of the loop (which I understand is the brighter bit) but there it was wrapping itself around the 3 belt stars!! ? Also visible was the angelfish nebula which unfortunately didn’t look like an angelfish more just a smudgy circle. But I guess the low height of Orion didn’t help things. Still nice to pick up a couple of new objects. And then off to bed for another few hours sleep...the new scope did well.

    Sinus Iridum is an impact crater filled with lava that lies northwest of Mare Imbrium. It is far from any landing site of the Apollo missions, the nearest (Apollo 15) is over 1000 km away. Scientists would like to take a look at basaltic chemistry to see how much they differ from the basalt samples collected at the Apollo 15 mission. Wrinkled ridges cross the bed, and in some places there are families of rocks stacked on the ridges of these crests. Where are these rocks coming from? From the mountain range? Many small irregularly shaped craters punctuate Sinus Iridum, how were they formed? Over the past four decades, the Moon has suffered an almost total abandonment, fortunately, in recent years, the Chinese are committed to taking this delay. Many unanswered questions, which perhaps the Yutu rover (Jade Rabit), who landed on Sinus Iridum may come to answer. This impact basin, approximately 100 km in diameter, was filled by at least 4 basaltic spills. On its "banks" there is a semicircular ring of dramatic mountains called the Jura Mountains, with the Heraclides Promontory at its far west and the Laplace Promontory at its eastern end, these promontories, which can be seen with perfection in this picture. From a closer look at the exact point on which the plains meet, look closely at the promontory of Laplace and its intriguing geology. Imagine yourself at the top at an altitude of 2600 meters observing the plain around you! Did you feel a chill? https://www.astrobin.com/full/392089/0/?nc=astroavani

    A surprise clear sky tonight pursuaded me to get the 12 inch dob set up. Wispy cloud now and then but the impromptu session delivered some good galaxy viewing in the Coma / Virgo area and also Ursa Major, Ursa Minor and Draco. Nice run down (or is it up ?) the Markarian's Chain with 11 galaxies showing then headed up for the Black Eye Galaxy and others in Coma B. Back to the fringes of our own galaxy for the Messier 3 globular cluster (Messier's first actual discovery apparently). On to Ursa Major practically overhead so M51 was showing two strong cores and more than a hint of spiral structure. M101 also showing well as a large somewhat unevenly illuminated patch with hints of a knotty structure. Ursa Minor and Draco revealed more galaxies (didn't note which I'm ashamed to say) but the Cat's Eye Nebula looked very bright and sharply defined with it's central star gleaming. Hercules had cleared the conifers so M13 and M92 globulars could not be ignored. Both looking wonderful at 199x and 265x - close to their photographic images with the 12 inches of aperture. Backing off the magnification a little to catch galaxy NGC 6207 in the same field of view as M13. Finished the session with the good old Ring Nebula as Lyra moved out of the Bristol skyglow and finally a Summer favourite - Albireo in Cygnus, with strongly contrasting coloured stars despite it's relatively low altitude. Post-session Googling found this very recent Sky & Telescope piece on the Markarian's Chain which might be helpful for those who wish to explore this rich area of the sky - and now is the time to do that ! https://www.skyandtelescope.com/observing/yanking-markarians-chain/

    I guess I would be totally out of imaging at the moment if I didn´t have my 3 nm Astrodon Ha-filter. First clear nights in over 2 months and of course that darn evil orb is up there, bright as ever! ? Managed to get a total of 76*5 minutes and I guess this is about as good as I can get it considering the full moon. Really can´t wait to get my hands on some O3 and S2 data for this one now! Oh, if only I could afford Astrodons for those as well... The field of view of my Sigma 500mm lens really fits this target! Thanks for watching, hope you like it ?

    Great night last night Managed to get just enough for this one. I let it pass the meridian with less than an inch to spare before fouling the mount. I was going to do a meridian flip and carry on but the haze came in so I parked the scope and called it a night. I think the noise levels are acceptable and will probably shelve this data and move onto something else. I used very loose G2V exposure weights for the RGB, Exposure times were 5x600in Red 5x420 in Green 5x560 in Blue and 2x1800 in Ha Thanks for looking

    This August I was lucky enough to go back to La Palma with the family for a couple of weeks. Perhaps more importantly I was able to take my cameras, and this time I hired a telescope over there rather than look at the skies wishing I had my scope with me. Same as last time we were unlucky with the weather, by La Palma standards, and several nights were lost to very thick Calima - dust laden winds blowing from the Sahara . These clog up the sky and raise the temperature quite drastically. It also severely hampered my ‘schedule’ of timelapses I wanted to get but living in the UK I can expect perhaps one night in two weeks to be clear. I can’t complain at the loss of 4-5 nights out of two weeks! Although it was frustrating to miss the Perseids again - they were on the one night it actually rained!! La Palma, perhaps surprisingly for one of the best locations for astronomy in the world, is a very cloudy island. When conditions are ‘normal’ it is usual for the inhabited parts of the island at less than 3000 ft to be frequently cloudy at night time. The cloud comes and goes but is often there and can be seen in several of my timelapses. There is an inversion later at approximately 3000ft though above which it is as clear as it’s cloudy below. So, if you can get high enough you can get above the clouds and almost guarantee starry skies. But, the same situations that give those clouds give us cloud waterfalls over the Cumbre Vieja (the ridge of hills linking the north and south of the island) and some amazing fog. I could go back to La Palma just to do timelapses of the fog/cloud! If you can get high enough it’s truly worth it. Up at altitude the skies are very steady and clear. I could see detail and texture in the Milky Way right through from beneath Scorpius/Sagittarius, right overhead and down into Cassiopeia and Perseus. The Milky Way was visible right down to the horizon and the stars were pinpoint spots of light - no twinkling, not even low on the horizon! There are various spots at the side of the road you can set up on - although be prepared for a number of cars to drive past with their lights full on! I was quite surprised at the number of cars - several of my timelapses show the observatories lit up by cars with their lights on full. Of course, arguably I was part of the problem… but then I was happy to drive around on sidelights (once I’d sorted out turning off the cars internal illumination!) I met and spoke with a surprising number of people, mostly Spanish and German. But it was frustrating whilst taking a timelapse to have people drive up and take pictures of themselves pointing a torch at the Milky Way, right in my field of view. Some of my timelapses show this despite my best efforts. I was able to take Tom up with me a couple of times (even Kate came up too one night!). I quite like being on my own at night but at altitude and with the humidity at less than 5% and the walking around often being on rocky broken volcanic surfaces it was good to have company. Of course, Tom being 10 he can see way better than me, something he was happy to point out regularly! I've put together a timelapse which I’ve called the Road to the Roque. Whether you approach the Roque from the east from Santa Cruz de la Palma or from the north west (Hoya Grande) it’s at the top of a long very switchbacked road. Driving up and down 7-8 times over the two weeks burned out the hire cars brakes - thank goodness for power steering! You can’t get to the top without going up the road - the views along the way were stunning so any timelapse I put together I wanted to include that part of the journey! The car brakes really were burned out. On the last day driving back to the airport they were noisy enough I felt it best to leave the car in second gear for the last 13km (downhill).. I hired a telescope for about a week out there from an outfit that turned out to be just 10 minutes up the road ( http://athos.org ) A German setup (the guy I spoke to, Jan, spoke perfect English!) which has to be the kind of place I’d happily just move to (just as soon as that lottery win comes in). They have a place with several small houses for accommodation, observing platforms, observatories, plenty of kit and are in a truly dark spot. Absolute Paradise! They kindly gave me a guided tour (they took care I didn’t wake up some of the astronomers that had been up all night) but the place was great. I have started siphoning off money from my joint account… (luckily Kate doesn’t go on SGL!). I hired an Evolution 6 with Starsense. My rationale was to have something I could carry around easily and for it to be smaller than my main scope at home and something I haven’t used before. It worked out perfectly, the little 6 inch was giving me much better views than my 10” Newt does a home and many an hour was spent looking at Mars, Saturn, Jupiter and Venus and looking at objects in the lower reaches of the Milky Way that we can’t normally see from the UK! The starsense was cool - level, aim north, hit a button… and it just worked! I could blether on for hours but won’t - here’s a link to the time-lapse I’ve done. Its missing some stuff I wanted to get but some stuff worked better than I’d expected so I can’t complain. A couple of the timelapses were done in strong dusty winds, in one of them I spent an hour hunched over the camera on it’s tripod holding a large black cloth as a shield for me and the camera from virtually gale force winds. Amazingly that one worked well although my shoulders weren’t so happy! Getting lost on the path on the way back down to the car was a bit hairy (the caldera was 20 ft to my right) but a bit of judicious Maps usage on my phone (most of the island provides at least 3G) enabled me to figure out that the all but invisible path I needed was just a few feet back from where I was… Finally, all else aside, I can’t overstate what having dark skies does. I live in a dark part of Devon and am grateful for that but the skies there were obscenely dark. The little villa we were staying in near Puntagorda on the north west of the island - you could walk literally straight out of the lit kitchen onto a patio and bang, there was the Milky Way, better than we even see it here, visible clearly in completely un dark adapted eyes… five minutes later and it’s enough to make you think… I could work from here you know, no need to go back to the UK…. I’ve started blethering again. Here’s the timelapse, I hope you enjoy it!

    The beautiful Needle Galaxy, 50 million light years away! I'm still getting to grips with RGB imaging, and not entirely convinced it's for me yet. Here is my image of NGC 4565 purely from last night. I devoted pretty much the entire night to single object, getting up at 12:30am to do a meridian flip and assess focus of RGB filters. LUM = 18000s RED = 7200s GREEN = 5400s BLUE = 6300s Stars look bigger than I would have liked, and the dust isnt as well resolved as I had imagined. Thanks, any comments would be very welcome. Adam.

    Second light for the Twin TEC140 rig. Starting early we managed 11 hours (5.5 per scope) on the Draco Trio, the spiral being NGC5981. (The rig is O'Donoghue-Milne-Penrice.) I'm beginning to think that the Luminance scope is out-shooting the colour slightly. I've been using 15 minute L subs on one side and 10 minute RGB on the other (to preserve stellar core colour.) I think some tests with 15 minute colour or a short booster colour run on the 'Lum' side of the rig might give better results but this is a conversation to have with the other kit owners as well.

    This image took me 18hrs to capture, quite a few subs had to be chucked out due to high clouds and really bad signal but in the end i managed to salvage a few to be able to process it. First image using Skywatcher Esprit 100 which consists of 50 x 300s (Ha, SII, OIII) subs. Fully processed in PI. Hope you like it. Comments and critiques are very welcomed

    The ultimate photo-op! Comet Iwamoto 2018/Y1 Guest Anne van Houwelingen from the Netherlands astutely spotted this possibility. He used our Tak 106/Atik 11 meg/Mesu 200 to image the comet in 2 minute subs, LRGB, just as it lay in the field of an image I already had from the same instrument a couple of years ago. He then processed versions with and without stars. We used the one with stars to obtain a very precise location and orientation for the comet so we can be certain that for two minutes, at least, it was in this exact position. We then combined the comet with the widefield by sharing ideas in Photoshop. A most enjoyable project. Olly and Anne van Houwelingen.

    Between the clouds, moon, neighbour's roof, nearby floodlights, and all the usual general life stuff, i've simply not been able to get any meaningful data on the HH (or Orion for that matter either) for the last 2 years! To say it's been my nemesis would be an understatement. At this rate i'll be glad to have that box ticked proper before i hit 50 ? So when we had a few hrs of clear sky (and no moon) a couple of weeks back i knew i had to give it a go. I luckily managed 9 x 7mins before it disappeared behind the neighbour's roof. I also have 5 subs of Ha (90 mins in total) from last March, although it wasn't of great quality (there was a nearly full moon right beside it, plus the neighbour's fire smoke was billowing up through the Fov ? ). I've been waiting patiently for more clear skies to add to this, but that 's not working out too well, lol. I really shouldn't be processing this, but all work and no imaging makes Ciaran a dull boy, so here goes nothin... 9 x 7mins with an IDAS-D1 4 x 1200s and 1 x 900s of Ha ~2.7 hrs in Total Stacked in APP and processed in PS. Lots of heavy lifting needed in PS, and i've reduced it to 50% in size as well. For now, at least, this will have to do. There's a lot of good HH's about so hopefully this one's not too hideous! ? I'll post what the 2 raw stacks looked like below as well, just for kicks. Here's the 9 x 7 mins raw stack (with DDP stretch): And here's the ~90min Ha raw stack:

    We were lucky enough to spend two weeks over Xmas and New Year on La Palma with the family. It was my first visit to the island and loved the place. First week we stayed at the Northwest (Puntagorda), that coincided with full moon, so did not do much imaging wise. However, a very memorable moment was when stepping outside between the main curse and dessert of Xmas eve dinner and within 5 seconds of looking up, I saw a large fireball meteor sweeping accross the sky and breaking up into several pieces. Second week we stayed about 10mins drive from Santa Cruz, so was worried about light pollution from the capital, but the first night it become obvious that the sky was still one of the best I've ever seen. The small light pollution is in the form of sodium lights, so can be dealt with by filters (apart from some flashing LED xmas lights around). The equipment I took was a Fuji X-T1, modded Canon 6D, Samyang 135mm and 35mm lenses, and Fornax lightrack II. Unfortunately, at the end I couldn't use the Canon as I found out there that its remote release connector is different, I use a Canon compatible intervallometer for the Fuji, and just assumed it was the same for the 6D. At home I've been using the 6D with the laptop, which I did not take with me to minimise the amount of kit. Learnt the hard way that everything needs to be tested before the trip and assume nothing. Anyway, I was enjoying using the X-T1 / 135mm combo on the Fornax, it was very quick to set up and worked very well. Fast lens meant that max exposure I needed was 2mins, which the fornax coped with easily. We visited the GTC and was hoping to see one of the other telescopes, but I've messed up the booking and bought tickets for the GTC twice, so that will have to be another time. Also drove up to the observatories in the evening and was hoping to do some imaging, I unpacked the equipment, but was so cold with strong winds (at some point I had 3 jackets on) that I basically bailed and just did some very wide field shots. The fun bit was when we got too cold and was ready to go down, the car wouldn't start. ? It was around 10pm, nobody around, no moon, so pitch dark. I'm still not sure why the car battery went flat, I run the Fornax off the cigarette lighter socket, but its power consumption could not be the reason. To have voltage in the cigarette lighter, the key had to be turned to ignition on, so I guess in that state something was taking current in the car, we did not have any interior / exterior lights on. We thought we might have to sleep in the car, when after about 20mins I saw a car driving down, jumped in front to ask for help, and the chinese couple inside very kindly helped to push the car to jump start it. This was a major struggle as the parking platform was lower than the road, so the car had to be pushed up the ramp. When the car eventually started I was ready to hug those friendly people but they were in a hurry... The sunset and the views of the milky way were amazing up there, still I've decided after this adventure that I rather put up with the little light pullution I have on the balkony of the nice warm house and my bed nearby. So, overall a few mishaps, but it just means that I definitely have to go back again in the summer, timed so that it coincides with new moon. Anyway below are some of the quickly processed images I took, also have some 46P data but haven't managed to process that to give anything decent yet. All processed in Astroart / Gimp, however my processing skills are not very advanced, still need to learn about layers, masking, etc.

    Well, I figured I'd stick with a target for the two flawless nights of clear skies I got Thursday and Friday, and picked on M51. Setup: Skywatcher 200PDS on EQ6-R, Baader LRGB in EFW Mini, ASI183MM-PRO at -10c, HitecAstro DC focus, guided with ASI120MC through a Primaluce Lab 60mm guidescope. Capture: Post ditching the crap frames, 51xL, 25xR, 27xG, 27xB, all 120s exposures. Processing: Stacked and processed entirely in PixInsight. General workflow was cal, hot pixel correction, registration, linear fit stacking, order a 32G RAM upgrade for next time, deconvolution on L, DBE on all, channel combination and photometric colour correction for RGB, multiscale linear transform noise reduction, histograms, LRGBCombination, final masked MLT and global TGVDenoise, a gentle ABE mixed in with PixelMath, local histogram equalization, a bit of gentle masked saturation tweaking, unsharpmask and curves. Quite happy with the result overall, though there's still some calibration issues - I have no way to make flats and my darks are out of date and not at 120s so PI's optimisation didn't quite null out all the amp glow from the 183. Deconv is still slightly unsatisfying, even with careful masking.

    Monday night it finally cleared and 2 am - 5 am on Tuesday morning I had my two Esprits directed at these two Messier galaxies. I collected the RGB with the ASI071MC (OSC) sitting on the Esprit 150 (38 x 5 min at gain 200 offset 30) and the Lum with the ASI1600MM (89 x 2 min at gain 139 offset 50) sitting on the Esprit 100. Ideally I should have collected the Lum with the larger scope but both galaxies would not have fit on the smaller chip of the ASI1600. Still, the lum collected by the smaller scope helped a lot. Stacking, aligning and a few other minor things in PI, the rest processed in PS. Totally 6.1 hour and very happy to finally get some data of my own!

    As the title says: Oi, this is not a foot warmer! A cheeky bird seems to think otherwise. Thankfully it didn't relax completely, if you know what I mean, and leave a small deposit slap bang in the middle of my Oculus dome!! I don't think that it is a widefield view of Corvus!

    A few weeks a go I was on a camping trip on the Norfolk coast. Those of you familiar with Kelling will know how good the skies can be on the Norfolk coast. On the first night, my family and two other families we were camping with walked down to the beach after dark. I'd brought my binoculars as there was no room for the dob in the car. As we sat on the beach, I pointed out the Milky Way, planets and some of the more obvious constellations. While we looked up a meteor streaked across the sky leaving a trail in it's wake. There was a collective gasp from our group. The children were full of questions and enjoyed looking through the binoculars. As we walked back to the tents, my daughter's friend commented "I didn't know space was so cool!!". The next morning, his mother asked if I could take him out again for some more stargazing. That night, one of the other dads and I took some of the older children into the dunes. I handed over the binoculars and talked each of them through finding Andromeda. I told them of the future collision between the Milky Way and Andromeda which filled them with questions. The double cluster was very clearly naked eye so that was the next target for them. At times we just sat back and talked about the cosmos and what may or may not be out there. I took a look at the dark nebulae which make up Barnard's E through the binoculars as we spoke. A brilliant orange/red moon rose up from the sea. After awhile, I spotted the Pleiades, which everyone enjoyed through the binoculars. Stargazing gave us all some memorable moments. Last night, my daughter's friend and his father came over for a look through my dob. On this occasion, I think the dad got the most out of it. My daughter and her friend have just started high school and were more keen on comparing notes on their respective new schools. Having said that, there were many gasps as we crept up the magnification on the Moon. Saturn sat just below Moon and so that was the next target. The "wooooow. I can see the rings" is always good to hear. Not much detail could be seen on Mars but I was able to point out one of the polar ice caps. With the sky getting darker, we moved onto some deep sky objects. The Owl cluster, NGC 457, is always a winner with children. Andromeda also impressed and I was able to point out M32 too. We go onto a bit of a roll and observed M57, Albireo, M13, the double cluster and finished on M81/M82. Each object produced it's own little set of questions from our guests. I felt quite accomplished showing them around the sky finding everything manually without needing to refer to an atlas. It's amazing how quickly you can build up knowledge of the sky. After our guests left and my household duties were taken care of, I headed outside for a little session of my own. Mars revealed a bit of surface detail with one darker region, though I saw better detail the night before. I moved onto another planet for my next observation, Neptune. I have an ambition to see Triton and spent a significant amount of time, trying to find the right magnification to reveal the tiny moon. On this occasion, it was not to be but this was my most serious attempt so far to see it. I'll give the dob a thorough collimation before my next attempt. I still very much enjoyed the pale disc of Neptune that was on display though. I added an OIII filter and went off in search of a new planetary nebulae, NGC6781 in Aquila. I believe this is also known as the Ghost of the Moon. It's quite a large planetary with lots of nebulosity on display. It didn't strike me as obviously looking like the moon. Perhaps darker skies would have revealed more detail and a greater likeness to explain the name. As the OIII filter was in, I moved up to M27. This was really stunning. The nebula presenting as a circle with a brighter "apple core" section. I recently treated myself to an ES82 30mm which now went into the focuser for a trip to Cygnus. The Crescent nebulae showed one brighter section and extended out further with averted version. The Veil was the target at the forefront of my mind when I purchased the ES82 and as I the Eastern Veil came into view, I was not disappointed. The 2 degree TFOV framed that section of the nebula perfectly and the Astronomik OIII really made it pop out. Without doubt, one of my best viewings of the Veil. Pickering's triangle was observable but not obvious unlike the Western Veil which also showed well though not quite as impressive as the Eastern section. The North American Nebulae was another treat with the ES82. It really is a big target. M33 was next to be viewed. I was absolutely thrilled when I realised that I could see NGC604 in direct vision. I managed to see it in my old 130mm scope but it was a real struggle compared to the view I now had. The nebula became even more obvious when using averted vision by focusing on the mag 11 star above it. I think this was the highlight of the session for me. There's something about seeing a nebula in another galaxy that's just awe inspiring. I added my H-Beta filter now and with the ES82 30mm back in the focuser, I went in search of my first viewing of the California nebulae. With the star Menkib in the eyepiece, I was initially disappointed... I couldn't see anything. Then slowly as I moved the scope slowly around, my eye started to pick up the nebulae. There was definitely one brighter section that was close to Menkib. That seemed to be the most obvious section to me. I picked up some more fainter nebulosity but not larger amounts. It was a good first observation. Darker skies and repeated visits will reveal more. My bed was calling but I could resist moving the scope around front to catch Comet 21/P. I made of point of looking for this every session over the summer. I have 16 recorded observations of it with the first being on the 20th July. My only disappointment has been missing it's pass through Auriga. I was shocked when SkySafari listed it as being in Orion. Autumn really is fast approaching! I found the comet without too much trouble. A hint of a tail but I've sent it much better when it was higher in the sky. I jumped over to the Pleiades, again using the ES82 30mm. The large exit pupil helped to bring out the Merope reflection nebula. It wasn't easy but I traced on edge using a couple of fainter stars as markers. I then verified what I believed I was seeing against SkySafari to confirm the observation. My observation was a match to SkySafari so success! With my final victory, I called it a night and headed in. I had to agree with my daughter's friend.... space is cool!

    Mornin', finished another picture. It shows a section of Pickering's triangle. This celestial object was discovered in 1904 by Williamina Fleming. It was commissioned by Edward Charles Pickering, director of the Harvard College Observatory, to examine photographic plates and catalog the stars and other celestial bodies. As was usual at the time, newly discovered objects were named after the employer and not after the assistant of the observatory who made the discovery. Williamina Fleming made many discoveries during her work for Edward Pickering. One of the most famous objects she discovered is the Horsehead Nebula. The picture was worked out as HaOIIIRGB. Besides the narrowband data, which clearly show the structures, there are also many hours of RGB in the image, which give the whole thing the beautiful colours. More data and larger view here: http://www.spaceimages.de/en/astrophotos/nebula/ngc-6979 or https://www.astrobin.com/364407/ Many greetings Jens

    Astrodarkness is rapidly coming back to Sweden and on Saturday night it cleared and I had my third chance to try my new ASI 071 cool pro. I aimed at getting the full 7 hours of darkness but various self-inflicted mishaps put it down to 5 hours. So here is 60 x 5 min at gain 200 and offset 30, chilled to -15°C, on the Esprit 150. I am amazed how free of noise this camera is. I did take 30 darks and used them but they may not have made much of a difference. No flats since I decided that dust bunnies have not had time to infect the system yet? and with the rather large image circle of the Esprit there is no signs of vignetting on this APS-C chip. Processing this faint area was quite a challenge and I appreciate comments and suggestions. While processing in PS I think I by mistake invented a new star suppression method: Inverted Hi Pass filtering. I may write a thread about that on the processing forum. For comparison I put in the image I managed to accomplish on the same object during 3 hours with my 5" ES 127ED reflector and Canon 60Da in January. Not sure if the telescope or the camera made up most of the difference, but there is quite a difference and I do not think it is not down to the small differnce in exposure time.

    My first attempt at imaging and processing a dark nebula, and probably my first really good run at the Atik 383L+ in some proper darkness. I imaged last night from 10pm so I had to content with the moon after midnight. I haven't used darks because I hadn't built a library of darks past 600s. Currently doing them now, takes a while at only 4 per hour! 18 x 900s L with Atik 383L+ 38 x 300s RBG with Canon 40d ED80 FF0.85x EQ6 It was nice to see some detail come through. Please feel free to offer advice. Processing with DSS and PS. I hadn't really a clue on how to process this, and it does look a bit harsh. The DSLR image was quite horrible too ?

    Hi SGL folks - I haven't posted for a long while & tbh we haven't managed very much imaging this year for a number of reason so far...equipment hassles but mainly clouds...clouds & more clouds! We had to resort to the venerable ASI224MC last week where the seeing was pretty decent - here's an image from that morning (26th March) as well as a 24-frame reversing animation using WinJupos to interpolate additional frames to complement the number of captures we actually took by making additional frames from adjacent captures... We also lashed out & bought a Stellarvue 10x60 finder scope & mounted it on a SkyWatcher adjustable alt/az guidescape mount which is secured via a dovetail bar & clamp to an extra "rail" I constructed from 3mm thick folded aluminium -this device to come in useful for hunting down Neptune more easily later in the year. Lastly I converted an old aluminium pier with detachable legs to accept the EQ8 head with a plate I made from a piece of scrap plate aluminium - the ability to break this all down into 4 very light & small pieces (3 legs & the pier column) means it is much simpler & far lighter/easy to take with us & assemble...the 3 self-levelling adjustable height feet I purchased for the legs makes levelling the entire setup much simpler, it's a veritable breeze now & weighs so much less than the very heavy stock steel EQ8 tripod! Hopefully the animated gif won't need clicking on to start its motion!

    It's been clear for a few days down in Devon. I say clear - it's been murky and hazy... but, a clear sky is a clear sky... In between getting subs for an image of the Leo Triplet I'm working on, I got some RGB of M13 as it rose up in the east over a couple of nights this last week after the Leo Triplet crossed the meridian and entered the murky light polluted skies in the direction of Exeter. M13 is one of those fairly rare objects that I think look every bit as good visually through a scope as on an image I can't quite get over the number of little galaxies that are visible if I stretch the image a lot more than I have here. As it is there are quite a few, one off to the upper right, one near the edge of the field of view, but also at least two visible on the right hand side near the end... I used an ASI1600mm-Pro through an Esprit 120 with Astronomik RGB filters. 20x 20 seconds each of L, R, G, B so less than 30 minutes data - actually, by dithering I probably doubled the time taken... Now I have to hope for more clear skies to finish off my Leo Triplet!

    Dear all, yesterday evening, I set up my 5" MAK on the terrace and had a look at the lunar terminator. A cone shedding some light to a dark and large crater attracted me. After doing the sketch, enjoyed looking up the craters in my lunar atlas books and in the "Geologic History of the Moon" (Don E. Wilhelms) to learn a bit about what I have sketched. Grimaldi: With a quick check in the maps it turned out to be basin Grimaldi. Named after an Italian physicist and with a diameter of around 170-170 km, this pre-Nectarian basin filled with dark lava (Eratosthenian age) is dominating the western part of the full moon. Yesterday the sun has raised just on the eastern rim of that nice area. Lohrmann: North of Grimaldi, a small lentil-shaped, bright crater rim with still black crater floor was popping up from the darkness: This was the crater Lohrmann with a diameter of just 30km which is supposed to be Nectarian age. Hevelius: The next crater at the terminator has been the Nectarian crater Hevelius. The surface of that crater named after the famous Polish astronomer Johan Hewelcke (Hevel) is supposed to have formed in later Lower-Imbrian age. Inside the 115km large crater, its central peak and the eastern rim of secondary crater Hevelius A appeared in light above the dark floor. Cavalerius: The last crater of the sketched chain further north, Cavalerius, has formed later in Eratosthenian age. Like Grimaldi named after an Italian, this time the mathematician Buonaventura Cavalieri. The diameter of the bright rim is about 60km. The crater floor was still in Lunar darkness. But now have a look at them: Telescope: Celestron 5" MAK Eyepiece: ExploreScientific 14mm/82° Date & Time: February 17th, 2019 / 2100 - 2210 CET Location: home terrace, Dusseldorf region, Germany Technique: Koh-i-Noor chalk and charcoal pens on black 'seawhite of Brighton' sketching paper Size: 21 cm x 28 cm Clear skies!

    Hey guys So with no new data at hand (or on the horizon it would seem) i decided to go back and re-process my short stack of M81 & M82, being the glutton for punishment that i am! The last time i re-processed this was about a year ago, so i was curious to see if i could get any more out of it. It's hideously low on data (nothing new there!), this is just 9 x 600s of colour (with an IDAS-D1) together with 7 x 1200s of Ha (which i only used to Lighten the Reds in the Ha jets of M82 and the small spiral regions of M81). AstroPixelProcessor used for stacking and gradient reduction, and PS for everything else. I mistakenly shot the colour at ISO 800, instead of the usual 200 i always use. A mistake i imagine every DSLR user has made before! And i have to say i really noticed it during processing. There was noticeably less colour in the stars. That being said, i was still able to bring out more colour in the core of M81 this time. And i think M82 looks a bit better as well, it was definitely over-sharpened before. I really love these targets, but they just make me wish i had more reach! CS! Here is the original thread: And here's the new one, including a cropped version:

    I think I'm going to have to get out the 8" reflector for galaxies but I thought I'd have a go at M63 under last nights clear skies with my Esprit 100 which was already setup. This is about 40min each for RGB and 3.3 hours for L with ZWO1600pro.

    Eagle and Swan: I was never really happy with the processing of this data and couldn't put my finger on what was wrong so I had another go. It also got me thinkiing about the summer skies which was no bad thing in the dead of winter! I hope the stars are now better and the emission nebulosity deeper. HaOIIILRGB.

    Hi everyone I saw a cheap 'Russian' -it says USSR on the lens ring- 300mm lens on eBay for €50. Just for curiosity I took this snap, never expecting anything like. I was surprised at the colour and corner correction it gave. It would be a great way to make a start in ap with a dslr; my Canon kit lens comes nowhere close. Interesting... 700d: 90 minutes @ ISO800

    The sky here has been on and off, meaning that it is sometiems clear when I take the last walk with my dog Balder, when it is supposed to be cloudy, and other nights I am set up and ready and everything is ruined by clouds. So, I have entertained myself with public data including this 0.4 hour image (4 x 4 subs of about 80 seconds of R, G, B and Ha) from the Liverpool Telecscope - a 2 metre RC scope on a mountain top on La Palma in the Canary Islands. I wish there had been more data but with a scope this size and a very very nice CCD camera it is still quite presentable.

    A very pretty image I cannot recall seeing on this forum before - but please correct me if I'm wrong ?. A mysterious target that Steve and I have just managed to capture sufficient data before the moon made its presence felt and it sunk too low on the horizon at e-Eye Spain. Much data was gathered at low altitude so I am very pleased at the result. There is quite a difference in the end result with the added Ha making comparisons with my LumHaRGB to many of the LRGB web reference images not accurate. I did wonder for a period whether I had added a red 'blob' to the reflection nebula! But it is there in the Ha data thank goodness. From APOD: "In this beautiful celestial still life composed with a cosmic brush, dusty nebula NGC 2170 shines at the upper left. Reflecting the light of nearby hot stars, NGC 2170 is joined by other bluish reflection nebulae, a compact red emission region, and streamers of obscuring dust against a backdrop of stars. Like the common household items still life painters often choose for their subjects, the clouds of gas, dust, and hot stars pictured here are also commonly found in this setting - a massive, star-forming molecular cloud in the constellation of the Unicorn (Monoceros). The giant molecular cloud, Mon R2, is impressively close, estimated to be only 2,400 light-years or so away. At that distance, this canvas would be about 15 light-years across." More data would have been better but we can always say that, can't we?

    Hello all This is a pretty hard one to do as it's so low in the sky. At its highest it's 27 degrees and I have a handy tree in that direction Plus my dithering on phd2 stopped working? Timed out but anyway here is what I managed with 16 x 360 sec over three sessions. Hope you like it. Comments and suggestions welcomed as always Gerry

    M101 has been challenging to say the least, particularly because of the high LP around here causing my luminance frames to have all sorts of funky gradients and banding and also issues with colour balance. I think I'm relatively happy with this result for now, although I'll definitely aim for more data (at least 10 hours of luminance) to get better SNR, and maybe add some Ha.
