    At last got a clear night after a few weeks. Took advantage to do a 5 hour long observing session. Viewed some galaxies in Leo towards the end. Thought I would share. Details in the images. All images taken live at the scope with no post processing.

    I got my EQ5 Pro and 130pds in July and i have taken images of M31 and M13 and a few other clusters but never any nebula. Thursday night was clear and the moon was out of the way so i thought i would take a chance and finally image M42. This is the result and i must say i'm very pleased with what i got. I kept the ISO to 640 as i didn't want to burn out the core. Its not perfect of course, i think its a bit off centre, the "coma" is quite obvious and it may be bit too blue (unmodded camera). Also i forgot to lock down the focus tube and i think it moved slightly as i was pressing buttons on the camera. It was freezing cold out there, i didn't get in until 2am and had to get up at 6am for work the next day, so i was like a zombie on Friday but it was totally worth it. regards Jason 40 x 50secs lights @ 640 ISO, Nikon D5300 unmodded 10 x Darks 18 x Flats 8 x Bias

    After a partly cloudy cold day I noticed some stars out tonight, not bad, not good, so out with the 90mm I go. Some nice sights were seen in Orion, the Flame neb, M78 and some nebs in Gemini. Changing locations to the dock to try M81/M82, the sky had cleared considerably- the 90mm showed those 2 bright galaxies well. As I kept obs things got better and better so......of to the races! to get the 15" The 15 showed so many objects, in UMA (bowl) many galaxies were re visited and some new ones surfaced. I saw around 20 galaxies or so- great warm up for the coming season! I just love M97's eyes, the 10mm BCO worked splendidly...did I say 10BCO?! First try that little EP gave me Sirius "B", easily, pretty pumped about that one. M1 was bright and typical,the Gemini nebs looked great, but it was just so good to get a bunch of galaxies again! I got 3 hrs observing in with temps at -30c, well worth it, and now I have galaxy fever!!

    I posted a thread back in November about dark sky sites in Shropshire and wanted to try one of the suggested sites, the Bog Car Park: https://goo.gl/maps/ZaY2iRUJW7R2 On Thursday night clear skies were forecast into the early hours of Friday morning so I decided to go for it. After I got home early from work the anticipation really started to build as I loaded the 250px into the Car. My main new target of choice would be the Rosette Nebula, which SGL membeers confirmed would be possible in the 10 inch scope under dark sites. An hour and 15 minutes later I arrived at the car park at around 7pm. Initial impressions of the site were very good with largely uninterrupted views except for a few smaller trees. The sky was completely clear and the milky way was immediately visible with an impressive amount of structure.Even at this time there was only a very small amount of sky glow visible on the horizon. Being a new site a waited for a while to see if there were any signs of 'activity' before setting up. After a while with no sign of anything I setup the Dob. I was just grabbing the 25mm xcel from the car boot when I heard meowing from in front of the car. Before I knew it a black and white cat was sat right beside me. Next thing I know he's jumped into the boot and managed to get over onto the back seats! 10 minutes later I finally persuaded him to come out of the car and he seemed happy to sit near the scope. I got the 25mm xcel into the eyepiece holder and aimed the Telrad target at Betelgeuse. From there is was easy enough to locate the central cluster of the Rosette in the finder scope. A quick look in the eyepiece revealed some very faint signs of nebulosity. So on with the OIII filter and what a transformation! The nebulosity was clearly visible, with smoky light and darker areas around the cluster. Really pleased with the view, it was beyond what I'd expected. Then it was on to M42, a spectacular site under the darker sky with its large wispy wings and twisting cloud like formations. It was a bit unexpected, but I actually preferred the view through the 25mm EP without the UHC filter. It was getting a bit colder so I went to the car to get my thicker beanie, with no sign of the cat this time. I got back to the scope and turned the base to look for M33, but it felt heavier. Then I realised the cat was sat on the base underneath the tube! Another 5 minutes later and I persuaded him to come out :-) Next up M33, which I've only seen as a faint smudge in my back garden, barely distinguishable from the background sky. I knew it would be well positioned, but will admit I had some trouble finding it. I think the sheer number of stars visible, compared with at home, took a bit of getting used to. When I did find M33 the core was distinguishable and hints of the spiral structure too. I had to have a look at the Andromeda galaxy, which was an easy spot in the Telrad. As always it was a very impressive sight, but this time I was able to make out the sharp edge created by the dust lanes. Again really pleased with that. I haven't seem M81 and M82 for some time so went looking for them. M81 had a nice bright core, but I didn't see any hint of spiral structure. Perhaps it may be possible when the galaxy is higher in the sky. M82 seemed to show slight mottling with the 25mm EP. Also whilst looking at M81 I spotted the galaxies ngc 3077 and 2976 for the first time. I couldn't make out any detail in them, but both were easily visible against the background sky. Finally I think I also viewed part of the North American Nebula, I could definitely see what looked like a patch of nebulosity to the left of Deneb, but it was fairly low in the sky at this point. I'd really have liked to stay longer, but with work in the morning and the drive home I had to pack up. I gave the cat a fuss, stroking him under the ear which seemed to go down very well as he was purring away again. All in all a fantastic evening under the darker sky. I'll definitely be doing more trips to this site and will be looking to venture further into Wales too. Andy.

    Concentric cratersCan you forget Endyminon for a moment and focus on a small detail?Look at the picture carefully and see if you notice something different.Realized that little concentric crater just below Endymion?It is part of a very special group of craters that still generate a large debate.This concentric crater still unassigned and about 6.5 km of the arrow in the picture, caught my attention because it is a classic concentric and still have a small craterelet almost exactly in the center thus giving the whole a target print. This can be seen in the picture attached in 3D obtained from the Quick Map.The Concentric Craters, or DC, are smaller Moon features that have been ignored at least for some 30 years. But now some scientists examined these features again. David Trang University of Hawaii and colleagues Jeff Gillis-Davis, Ray Hawke and Ben Bussey, published and recently presented a paper at the Lunar & Planetary Science Conference, where they report that found 14 more CCs than a previous list made 30 years ago, using it for data from the Clementine, Kaguya and LRO probes to distinguish and confirm the identified features. Almost all the researchers now agree that the main crater is a small impact crater, normal and the question is whether the inner ring or torus is formed in association with the impact or is the result of some endogenic modification (endogenic is a word that It means that something has been created internally rather than created by external forces). The group of David found evidence against the hypothesis that the torus is formed by a simultaneous double layered impact in the target by volcanic activity or viscous relaxation. They noted that the distribution of CC along the edges of the seas is very similar to the fractured inside craters. As it is believed that the interior Fractured craters are impact craters modified by igneous intrusions, they proposed without details that these intrusions can also modify the interior of CCs. This is consistent with evidence that the CCs have a spectral signature virtually identical to the material located beyond the crater rim, implying that there was at least this point, volcanic extrusions. David showed this with the DC Firmicus C crater 14 kilometers in diameter, as an evocative example of volcanic material that can be associated with CC but mostly is not visible. The small dark spot on the torus seems to be pyroclastic excavated by small impact crater. It will be interesting to follow the work of these researchers and see if they will be able to find the same type of feature in other CCs and if they can develop an explanation of how an intrusion would create the morphology of the CC.Source: Space TodayAdaptation and text: Avani Soareshttp://www.astrobin.com/full/235942/0/

    Hello, i bought myself a Skywatcher Esprit 100 for christmas as i wanted to have a wider field of view and also an easier handling compared to my GSO 8" F5 newton. Luckily, over christmas the weathergod was nice and i had a few good nights. This is 10hrs integration time with a stock Nikon D800 and the Skywatcher Esprit 100 on a NEQ6. Do the colors and brightness look more or less ok on your screen? I exported this image with color profile but on some screens it looks greenish and just too bright.best regardsMatthias

    I managed to get the scope out the other night again thats two nights now in the past couple of months, things are looking up. Anyhow here's my attempt at M31, still struggling to get it to all come together, especially the processing bit, but I think i'm making progress.

    I managed 141 sessions including solar in 2015, so don't consider it to be a bad year, although the weather and seeing could have been much better! Some have just be ten or fifteen miunte sessions imaging the moon or Sun in white light with my DSLR and 80ED scope on an MDF mount. It makes a very quick set up if I see an opportunity, and I've captured a number of interesting transits across the Sun and Moon with this method.

    After watching Adam Block's latest video PS tutorial ("Cosmic Canvas"), I've had another go at reprocessing my third attempt at M31. This time I tried out two new techniques: Shadows and Highlights for increasing colour and HDR Toning on the synthetic luminance for boosting contrast. I was impressed by both methods, so I'll incorporate these into my evolving PS workflow. LIGHTS: 42 x 300s + 23 x 600s; DARKS: 30; BIAS: 100; FLATS: 40. Alan

    Ok, so i finally managed to get out to a dark sky location (green zone on an LP map) to acquire some (hopefully decent!) M31 data. And wow, the difference in the quality of data when taken from a dark sky location compared to a red zone location is night and day! Unfortunately though, i was fighting the tech gremlins for most of the 3 hrs i was there, so i only managed to gather a total of 27 mins of exposure (1 x 6 mins and 3 x 7 mins, all dithered) at ISO 800. I took about 15 flats, and created a master Bias from about 300 or so. I had to take darks indoors, the following night (again, about 15ish) so seeing as the temps were hugely different, i unticked 'Dark Optimization' in DSS and just used them for Hot Pixel Detection instead. Not sure if this method even makes sense?! After experimenting with DSS, it would seem that (for me at least) it is much easier to bring out the colours in PS if i choose the 'Per Channel Background Calibration' option in DSS instead of 'RGB Channels Background Calibration'. Not sure if others have had the same experience? As you can imagine, keeping the noise under control was the hardest part of the processing. I've included a link below for a .zip file with the 4 lights, and master Bias, Flat, and Dark files, in case anyone out there fancies a challenge and wants to show off their processing skills, as i'm not sure how i'm progressing tbh. My rough workflow goes something like: 1. Stack in DSS (in addition to the two points above, i used Average for the Lights, as i had so few to work with) 2. Crop out the stacking artefacts in PixInsight L.E. No need for DBE, as far as i could tell. 3. DDP (without sharpening) in Maxim DL to get a near optimum stretch (i backed off a bit on the background setting to darken it a bit) 4. Then into PS for some Carboni's Tools and the usual guff. I boosted the colour by creating 2 new layers, making the top Soft Light, merging it to the one below which in turn i changed to Color. Repeat as necessary. Tips most welcome!

    Another step closer to something good, last night was a belter in terms of sky quality so I raked in another 90min per pane and its starting to have an effect on the noise levels. Still not perfect, but im now able to present it at a larger scale (75%) and throw in some contrast enhancement. Probably another 5 hour stint will be enough to get it where I want it, and Tuesday night is looking like its going to be the night for it (fingers crossed!). Ive stll not bothered with an M42 core just yet, Im saving that for the final version.... I'll just be glad when this bit is done becuase the DSLR data should be easier to get as it will cover most of this area in just two panes. 4.5hrs per pane (x3) 900s subs (Ha) Star71, Atik 383L+, NEQ6 Thanks for looking! https://flic.kr/p/CQiSet

    Hello all, At what seemed like an age, finally there was a clear night so I decided to have at a go at M45. I only had limited time before it dissapeared behind my house. My set up is: Skywatcher 150PDS EQ5 Pro Mount Canon 550D with a Skywatcher coma corrector and light pollution filter PHD2 using a QHY5 cam and 9x50 Skywatcher finder (Dithering enabled) Image data: 12 x 200 second lights ISO 800 12 x 200 second darks 15 x Flats 15 x Bias I'm still finding my way around and most of what I do is trial and error so I would be very grateful for any advice etc. I did post some M31 shots earlier so I thought M45 would be a good next target. Just to add, the images where taken from Birmingham UK under very light polluted skies. I was hoping to get more nebulosity with 200 second subs but I think I may have to go longer next time as what I got out from the image was hard work!! Next on my list is a Modded Canon EOS before I have a go at M42.

    Thursday night was the first clear sky for a long time here, so I had a go at the Pacman (NGC281). This image really needs some Ha and Olll, but I only had time for LRGB (16x5 minutes for each). I was hoping to add some Ha last night, but no chance. Tak and Atik as below. Whilst observing a refocusing run later in the evening, I noticed the stars didn’t look quite correct and suspected either the collimation was out or the off-axis guider had slipped into the field of view. However, I continued imaging - skies like that are too rare to start serious investigations. In any case, the in-focus images looked fine even at 400% enlargement, and the guiding was working very well. So when I came to put everything away, I found a small bag of silica gel resting up against the objective (I always keep one there in this climate) but had forgotten to take it out when setting up…… I had not noticed it when I had checked the objective for dew because it was on the lower side where I could not see easily. And I believe that this is the reason for the spikes on the brighter stars which appeared during processing. Ah well, it’s not the first mistake like that I have made, and fortunately it doesn’t seem to have detracted too much from the image. Almost certainly I will use the subs again when I get some Ha. Any criticisms would be very welcome. Chris

    Good evening Finally a clear night on the 7th of January so I made the most of it. First a look at Comet C2013 X1 in Pegasus..It is in outburst and I could see the square of Pegasus between the roof and tree so I thought I would give it a go. It was a lovely bright ball between two field stars so an excellent start to the session. Here is my observation note and pic. So on to galaxies. Basically I was touring Gemini, Canis Minor and Lynx. A long list of observations followed including the five that surround Caster that I read about in Walter Scott Houstons deeps sky wonders book... But my favourite discovery of the night came from looking for UGC 3696 which is near NGC 2329 I had seen before in Lynx. As I checked the observation on Carte Du Ciel I noticed a spray of fuzzies all around. Here is the Kopernik.org image of the area. NGC 2329 is at the centre of this mage and UGC 3696 is above and left. Both galaxies are mag 13 and both were visible with averted vision fairly easily in my 16 inch scope. So a bit more research and it turns out NGC 2329 is the anchor galaxy of Cluster Abell 569 250 million light years away. It is a large cluster and is connected with the Pisces Perseus wall of galaxies. Sinbad lists 85 children on NGC 2329 which itself is a massive elliptical giant spewing out jets of gas and xrays and the like... Here is the cluster plot which gives you some sense of what I stumbled across. Anyway I had also viewed MCG 8-13-61 in my galaxies that night which turns out to be another cluster member. Looking back through my observations from November 2015 I find I have seen NGC 2320 / NGC 2340 and NGC 2322 which are also members. So a great evening of viewing enhanced by post viewing research. I must be careful otherwise the above might read like one of those chapters in the Webb society magazines or their galaxy of the month written by Owen Brazell! Finally it is 22.50 I am finding IC 2193 near Caster a bit hard...Am I dewing up? No its cloud after a totally clear evening....Oh my ...in I go on to the HTC rainfall radar...Oh no a red blob coming towards....wait that's rain on the skylight...Josh help me get the scope in..its raining...So in with the scope and out with the hair dryer to dry off the raindrops...so its acid rain drops v Orion Hilux coatings..I will let you know who wins!

    Hello, My last night observation of Messier 35.Beautiful open Cluster. Messier 35 or NGC 2168 is an open Cluster in the constellation of Gemini apparent mag. 5.3. It was discovered by Philippe Loys de Chesheaux in 1745 and independently discovered by John Bevis before 1750. The cluster is scattered over an area of the sky almost the size of the full moon and is located 850parsecs (2,800 lights years) from the Earth. (Wikipedia) The compact open Cluster NGC 2158 lies directly southwest of M35. Dob Synta Sky-Watcher F.L.1200/f4.7 T/S plossl 30mm F.O.V :70 Mammari Thanks for looking Marios

    Had a pleasant couple of hours in the back garden. Did a bit of visual, but really wanted to make sure I could get the DSLR focused on the William Optics 110 using the field flattener. Had a quick go at M45 The Pleiades, but the clouds came in thick and fast at around 8pm so I decided to pack up. Not going to be heading down to Winscar, but I hope it stops clear for you all down there. Was nice to just have a look through a few EPs tonight

    Finished my flight case (for now), and fitted my other EPs, 2x barlow and colour/moon filters from my other Celestron kit into the same case. As I treat myself to new EPs I can move out any that I won't be using as much. At least I only have to grab the one case when I go out viewing now. Job's a good 'un!

    First clear night for over a month. Was goner give the M35 region a good bashing but after 16 subs had to packup as I did'nt feel to well. Anyway, wanted to bring out more of the faint stuff. Not enough subs and I went for a focal length of 70mm but that was a mistake as it had terrible gradients, three iterations of ABE sort of saved something. So 16x300secs Canon 60Da EF 70-200mm L @ f/4 ISO 800, all subs dithered with the Lacerta.

    I am thinking of altering the mirrors in my telescope to turn it into a Periscope, because, if it does not stop raining here I think I am going to need one. Got up the other morning looked out of the door and saw Jupiter, went for my bins and when I got back to the door it was raining. I was only gone a minute. I am a patient person in general but I have not has my scope out for three months now and it is starting to get to me. I dont have a permanent set up so an odd hour here and there is no good to me. Well, I have got that off my chest now, can only hope it will clear up soon but I am not holding my breath ( unless I end up under water that is ) but at least then I can use my new periscope........

    One of the best loved Victorian amateur astronomers was the Rev Thomas William Webb who wrote 'Celestral Objects for Common Telescopes'. Webb was a rural clergyman in Herefordshire and a few years ago Janet and Mark Robinson produced a lovely book called 'The Stargazer of Hardwicke'. The Webb Society is named in his honour and a few years ago I was asked to visit Hardwicke (to celebrate the 150th anniversary of the book) and show objects in the nights sky. It is so dark in Hardwicke with no light pollution. If you are in Herefordshire its worth visiting the Church where he was Vicar. Book details ISBN 0 85244 666 7

    Hi Everyone This is my 2nd attempt on M31. Shot through the economical achromat Orion ST 80A on NEQ6 Pro. I know, technically the photograph may not be perfect, but for a newbie like me, the photograph was really rewarding. This is an integrated exposure time of 52 minutes with 4 dark frames and 4 bias framed stacked in DSS. I was so excited when the stacked image popped on the screen. It almost filled the entire FOV. Later I did some post processing in Lightroom, being careful not to tamper the original data much. One more thing I realized while attempting in this photo. That is, how correct it is when we say, that dark skies matter a ton. I took this photograph from a hill station in the Indian Himalayas called Mukteshwar in the state of Uttarakhand. The sky was absolutely clear and the M31 was visible to naked eye. I would really welcome suggestions on how to improve and take better image using the same scope i.e. ST 80A. Please please advice......looking forward... Regards Pankaj

    Well as a newbie to Astrophotography I love looking at everyone else's pictures. But there is still something special about your own pictures no matter how they compare to others. Here's my first attempt at Jupiter with a ZWO120MM-S on a Sky Watcher ED-80.

    Having had no luck getting a decent image of Andromeda so far, so I am pleased with this. 14 X 5 min, iso 800, DSS, Photoshop. My third image from yesterdays all nighter. It is not framed perfectly, but I can't get it all in anyway on my 150 pds. A Star 71 would be nice if anyone wants to donate one to the Stargeezers coffers! One more to process, but as I was up til 5.00am, I think its time for bed.

    Olly, for DSOs I agree with you. For planets and doubles being able to fine tune the magnification to the seeing conditions makes it worthwhile having plenty of options at the high end. Plus, half empty eyepiece cases don't look anywhere near as nice [emoji6]

    weather has been total pants here for months. Managed to get a few quick shots with a Canon 200mm lens and a Atik 428ex OSC. First time using PHD2 guiding as well. Worked fine although errors were a bit much. Seeing was not too great though. Literally just about 5 or 6, 6 min subs each image, so noise is not great. It was just good to 'keep my hand in' as it where

    Its a very very unlucky time to get into the hobby right now. I was so lucky when I bought my scope, the jet stream was behaving itself and I got lots and lots of viewing in. I achieved first light within 1/2 hour of getting home on a lovely afternoon moon ! The first year I got so many views, this year has been rough to say the least. There is currently no sign of an end to this continual bombardment of weather fronts as the longer term forecast pretty much has the jet stream oscillating front after front onto us. On a more positive note, between fronts when the jet stream drops south, the free floating particulates in the air are at a low, the transparency should be good so these small in-between sessions should be taken advantage of. It takes finer planning as sudden downpours are never that far away. My interest remains high even in times of frustration, however I do feel a little sorry for people who got scopes over the festive period and have not had a good opportunity to really cut their teeth on this great past time. The good times will come, I am personally looking forward to a window of opportunity that lasts more than 3 hours Times like this often allow me to grab the Burnham's Celestial Handbooks from the shelf, and gain some inspiration from the late Robert.

    Been getting up every morning for a view. This morning there was a gap in the Permacloud. Catalina was naked eye by averted vision. Just left of M3 between Arcturus and Cor Caroli. Seginus helped fixing it in x8 and a real glow in x15 bins. Got the Light Bucket out and a wonderful view using a 31mm Aspheric. Then up 21mm to 10mm. The glow had a brighter side, but even by averted I couldn't make out any tail. Still a wonderfully bright large comet, worth getting up for. Jupiter being high and bright in the south, I caught the grs transit after 6. Although seeing wasn't good, the views were best at x150. This showed a very dark grs with a dark barge in the northern belt. The belts looked darker and more tortuous than last opposition. Three moons were buzzing on one side , like bees ! Clear skies ! Nick.

    Okay so it turns out i don't know when to quit after all The weather's been so abysmal here in the UK recently i'm literally left with not other option but to have another go at processing this high quality (but low quantity) data. Differences this time were: Using Lab Colour. It's tricky, but it's by far the best way to balance the colours before moving on to saturation. I went back to using the darks (perhaps foolishly) because they cleaned up so many bad R,G,and B pixels. The side effect was some holes in the data from the mismatched darks subtraction, however, i was able to combat this by adding a Median Noise filter of 2 pixels in a new layer, then using a layer mask and painting in only the areas where i wanted to make the corrections (mainly just parts of the spiral arms, it's not so noticeable in the deep space). Magic Wand tool is out. My new friend is Select->Color Range. I had to use this a lot, but it really helped! Carboni's Tools ->Enhance DSO and Reduce Stars. At first i wasn't sure if i liked this. It seems to blur all the stars slightly, but it certainly does do a good job of bringing the galaxy to the forefront and making the stars seem more like a part of the background, which i suppose is a good thing. And finally, i stupidly didn't know to frame the shot diagonally, instead going for a horizontal one. Doh! So, just for kicks, i rotated it in PS and clone stamped in the top-left and bottom-right triangular sections with some deep space (i know, tut-tut!). But hey, at least i now have a desktop background i can use until i get another crack at this target (hopefully next week!). Clear skies folks!

    Good question. I think Cassiopeia for me as it contains tons of objects (mostly open clusters) and is useful for hopping to M31 and the double cluster, which are both beautiful.

    I can't hope to compete with the wonderful CCD images on here but here's a few with my Canon 1200d. You know what they are. Peter

    Here is my contribution. Its my first real year after a false start last year so am very pleased overall. Even produced a calendar for the family at Christmas All shot with my modified 100D and processed with DSS, Photoshop and occasionally a touch of DBE (from Pixinsight Lite). Happy 2016, and clear skies all! Cone Nebula (Christmas tree) Just reprocessed. M42 (Orion Nebula) NGC 7000 (North American Nebula) Flame and Horsehead Nebulas Rosette Nebula. That's my 20 MB worth!

    Hmm. Just 5 images? I don't know what are the best so I'll just choose some randomly... First 3 are using the NP127is and Atik490EX camera, last 2 are using the NP127is and G4-16000 camera. ChrisH

    Here's a selection from 2015 - I did add up all of the imaging time on this and it is 277 hours. A combination of cameras (Sony chip and kodak chip) and a couple of scopes (FSQ85, RC8 and ODK10) You can see a larger res version on my website

    Friends, I just passed my first 9 months as an astrophotography pretender, and checking my log book I had only 15 nights under the sky so far (due to clouds, moon, other commitments and 4-5 summer months of light nights up here). No wonder I almost panic when the sky is clear and I can open the roof of my obsy. Here are my contributions, all taken with a Canon 60Da and either a 127mm or 80 mm Explore Scientific budget triplet apo. I have to say that I am quite pleased with the scopes and camera and the weaknesses are mainly due to too few subs as I am still too excited about moving onto the next target. I have bought a mono CCD camera and filters and aim to start on this new steep learning curve as soon as it looks like I will get a few nights in a row... They are all well known targets that need no presentation.
