  1. LRGB and Ha The Horse Head Nebula In Orion. Imaged with the 12.5 RCOS @ f9 and FLI 16803 36x 600 in Luminance and 12x 900s in each RGB total 15hrs. High haze effected some of the data but the weather in Spain hasn't been at its best. This scope I did a complete strip down and refurbish including a nice shiny recoat of it's stunning Zerodur optics ...that was a very nerve racking day I can tell you. Thanks for looking… Peter Shah

  2. I have to admit that I knew little about Astronomy Now until @ollypenrice asked me if he could use my Squid image to illustrate the possibilities of the new generation OSC CMOS cameras (ASI2600MC in my case) in the January issue. One bonus for me was that the magazine sent me a free issue and I liked it a lot. I also noticed that they had a gallery section, so I though why not give it a try. Apparently they liked my image so it is now in the March issue and they gave me a 15 pound voucher. I have now spent that and a bit more on a yearly subscription (after Swedish customs have ensured me that

  3. The weather has been absolutely shocking here in the NE since christmas. So when I had a clear window of about 2 hours last week I took the opportunity to try and grab an hour on M42, in the end I ended up with 18 x 2.5 minutes subs. So here it is: Stock Canon 80D and SW 72ED on HEQ5 Pro No filters were used and the image was taken from my Bortle 8 garden.

  4. This time last year whilst on a dark sky skiing holiday I remember looking at the Rosette thinking how amazing it was and that I'd need to image it again. Ive had to settle for roughly 2hrs on each channel as the weather gods haven't been kind recently! Thanks for looking, Ken

  5. So after 7 weeks of unremitting cloud I finally got the new camera outside. for all of 90 minutes before Orion started to get too low and clouds started to build again. But at least I got an image. This is 15 each of 180s, 120s and 60s. I did that partly to get a handle on how the camera performs and of course to try to get some detail in the core. SW 80ED, NEQ6, ASI2600mc pro, L-eNhance It is stacked in APP using the Ha-Oiii colour algorithm then a very quick hash through in Pixinsight. Overall I'm pretty happy with it - a bit grainy when you zoom in hard and I'm not sure

  6. Tecnosky 125/975 F7.8 FPL-53 ED Doublet APO Refractor Arrived this morning from Astrograph. First impressions are it’s a very solid and well made scope. Finish is a WO like pebble finish not gloss white. Focuser is a smooth 2.5” R&P and has a 2” twist lock on it. Comes with a typical Vixen dovetail bar but have Losmandy plate ready to fit and also a StellaMira carry handle. Scope is bench tested by Tecnosky and then checked again by Astrograph. Manufacturers blurb. The Tecnosky 125/975 FPL-53 Doublet is a bargain in the 5" refractor class. With FPL-53 Super ED g

  7. This is a two panel mosaic of dark nebulae in the Taurus Molecular Cloud. The relatively long total integration time at f/2 brought out quite a lot of colour and dust. The nebula to the left is Barnard 14 (containing the bright IC2087) and the one to the right is Barnard 10. The long stretch of dark nebulosity at the bottom right is NGC1539. From Wikipedia: The Taurus Molecular Cloud is a molecular cloud in the constellations Taurus and Auriga. This cloud hosts a stellar nursery containing hundreds of newly formed stars. The Taurus Molecular Cloud is only 140 pc (430 ly) away from earth,

  8. Finally got around to processing my attempt at a Mars animation from all the way back in October, Would have gone on longer but was interrupted by cloud. Think that was what put me off, thinking it was incomplete. Turned out well though, for a first attempt, some frames were awful but I have included a couple of the frames that look really good. I know that the south pole is at the top but it just didn't look right the other way around! Taken with a asi120mm through a C9.25 with best 50% of 10000 frames in each RGB channel. Mars Oct 2020.mp4

  9. This is a two panel mosaic where I used one of the panels from my recent mosaic, containing Barnard 14 (with IC2087), and added a new panel (the bottom half of the image) dominated by Barnard 18. These nebulae belong to the Taurus Molecular Cloud. 12 hours of total integration time with the RASA 8 at f/2 brings out quite a lot of light and colour even in dark nebulosity. Imaged 10 - 14 Feb with the RASA 8 and ASI2600MC (gain 100) without filter. 180 x 4 min. Stacked in PI and processed in PS and PI. I also post an annotatded low-resolution version grabbed from Astrobin. Fro

  12. Very happy chap today. Actually dithered quite a bit whether to buy the StellaMira 80mm (crayford focuser) or an alternative however circumstances deemed the StellaMira as the one to be. Ooh it's lovely. Plus a few other bits - Scopetech Zero, ADM clamp and a Baader finder shoe. Thanks to the contributors on the various posts at SGL as to suggestions for appropriate mounts and clamps.

  13. Just captured this image of the heart of Orion my recently purchased samyang135, though I was hoping for a bit more structure at the bottom and really had to work hard on this image, straight out of the camera there was much more contrast in the centre 50% of the image than the outer parts which looked washed out ( almost like reverse vignetting ), im wondering if my Baader 7nm Ha filter is going off band at f2.8, can't decide wether to stop the lens down ( defeats the purpose of buying it ) or upgrade to an Antlia 3nm filter which ive seen examples of working well with RASAs at f2.2. my filt

  14. The weather finally broke long enough this week for me to start the project ive been wanting to do for the last 3 months. Managed to get a few hours on it spread over 2 nights but the moon will be in the way for the next 2 weeks and im loosing Orion behind a tree earlier every night now so will remain a work in progress until next winter. Anyway this is the widest and deepest image ive ever captured of the heart of Orion, though I was hoping for a bit more structure at the bottom, when straight out of the camera there was much more contrast in the centre 50% of the image than the outer pa

  15. This is one of the lesser known galaxy groups. Even Simbad has very limited data on the fainter objects that are visible in the image. The brightest galaxy, and the only one with notable detail, is ngc 2469, a mere 150 Mly distant. Most other galaxies are at a distance of between 370 and 390 Mly from our own Milky Way, a few as far as 600 Mly. To put these distances in some perspective, about 380 milion years ago, when light left these deep sky objects, life on earth decided it was time to leave the seas and start inhabiting dry land. Ngc 2469, right off center, is a Sbc t

  18. For me- this was a hard one....so I am not sure how it will go down. I tried it in January and gave up (even though I obviously kept the data). Again now, very recently, I went back to it until the weather (humidity mostly) has put a stop to any imaging once again. Last night though, I actually combined the Jan & Feb data - even though the imaging scale and the camera rotation had both changed considerably. APP did a fantastic job...bringing everything together ..... and then with quite a crop....I came up with a result. (Total time: 23½ hours). More details & larger image @ https://

  19. Dear all, tonight I finished the weekend with a tiny sketch of the Eratosthenian-age crater Bullialdus (60km diameter) in the west of Mare Nubium. Apart from Bullialdus you can see Lubiniezky F in the North, Bullialdus A, and B south of the main crater and the tiny Bullialdus E and L in the west of it. Today I once again selected the small size of just 8x12cm for the sketch.

  24. Managed to add some 2 hours of H-alpha data acquired yesterday evening with my ASI183MM-Pro, Astronomik 12 nm H-alpha filter, and Canon 200 mm F/2.8 L lens. Might want to re-stack the lot, as there are some artefacts on the edges, and I had issues with the camera being reported as an OSC camera with RGGB Bayer pattern.

  25. A few of Florence who is out for a run around tonight. Just a lunar session most likely, maybe a few doubles later. The cloud seems to have cleared, but the seeing is quite variable. Still, nice to see Schröter’s valley again. I was using my Nag Zooms earlier but then fiddled around with binoviewers for a while until I got them working at high power, much better views, far fewer floaters!

  26. I went for it. After falling in love with my William Optics 40mm 70° eyepiece, I decided that I wanted two more complimentary widefield eyepieces. I went for the 17.5 mm and 9 mm Baader Morpheus eyepieces. And the best diagonal I could find to go with them - the Baader BBHS Sitall mirror diagonal. Now it's all cloudy in my location (of course), but I will share my impressions about this beautiful kit as soon as I get some clear skies!

  29. "Being hit in my retina by the sheer, live, almost 3D brightness of seeing something like the trapezium or the Castor double through an eyepiece." It knocked me sideways when I first saw this in my eyepiece and it still impresses me. I have only ever seen this "effect" through the eyepiece and never in an image. An astrophotographer can share their image but all I have is something in my memory that I am unable to share and can only pitifully try to explain with words. Help!

  32. Finally after months of permacloud I got to see the sun today, thought I'd get an image of the new sun spot but the seeing was rubbish so I didn't bother. However, there was a bright prom on SW limb which looked more interesting and managed to get this short time lapse (30mis actual time) before the clouds rolled in

  33. Discovered in 1788 by William Herschel, NGC 2419 is one of the most massive and brightest globular clusters but appears as a dim 9th Magnitude object due to its large (275,000 light years) distance from Earth. The bright blue star to the left of NGC 2419 in the image below is HD60771, which is much closer, being only 350 light years distant. In 1944, the American astronomer named it the “Intergalactic Tramp”, since it was once (erroneously) thought not to be orbit around our galaxy but rather wandering the space between Earth and the even more distant galaxies.

  35. Part two of my reviews just to show you don't have to spend a lot to enjoy astronomy. This is out of sequence,it should be part 3 but more testing required on what should have been part2. part1 is here: I've managed to make it through most of my astronomy years with hardly a nod to the humble Plossl...until the last 6months or so. As most of my ep's are worthy if unremarkable Japanese old school designs, i thought it was high time i picked up some cheap ep's for field trips,quick peeks etc. My eye was drawn to FLO's Astro Essentials Plossls, as they were a) cheap &a

  36. So I put the scope out to acclimatise at around 1900, hoping that the clouds would clear. I know that I wouldn't get to see much as the moon is waxing to full and it was so bright that any DSO would be nigh on impossible. That wasn't an issue however as tonight was more about getting used to moving the scope and getting to grips with the Telrad. I'd read a little about star hopping with the Telrad and how you could put the reticle on various of the apps to find DSO's so I wanted to spend a little time just 'getting used' to lining it up and getting comfortable with it. So, having previou

  37. Hey all, I am starting to really have an interest in saturated lunar surfaces. As much as I generally enjoy B&W high resolution imaging of surfaces, I also find myself just as pleased looking at highly saturated surfaces too, despite being lower resolution. I really am drawn to deep browns and purples. Anyhow, while this may not be everyone's cup of tea, I'm trying to learn to align the color as close as I can to keep getting consistent results before buying a large color sensor to work with further. So for now, I'm practicing with the only color sensor I have, the 224MC. C8 Edge

  41. Part 1 of my recent 'mid-life crisis' purchases arrived today. It's a second (or 3rd/4th) hand Meade Field Tripod I found for sale here in Ireland. It's a beast, the top plate that comes with it is huge (I don't have small hands!) but thankfully it also comes off. I swapped some email with Meade in the UK and then the US, and they say this tripod is able to take up to 30Kg. So it should be fine for my 130P! For the price I got it for, I couldn't resist, it should be a tripod for life. And quite a bit more stable than the aluminium SkyWatcher tripod I currently have. The fun part is connecting

  42. Picked up a used ST80 on EBay as a wide-field companion to a SW Mak 127, and had only been able to point at terrestrial targets, align the RDF etc until last night presented an opportunity for a quick view of the moon, the only object visible through a blanket of high cloud. I was keen to do this as have read widely varying reports of ST80 performance on bright objects so the moon was a good "how bad can it be?" test. With a Baader Zoom and stock SW star diagonal (90 degree) quickly thrown on to a lightweight photo tripod I was really happy with the view - very crisp, bright, not d

  44. It has been a while since we had a break from this weather. After I finished some late evening online meetings, I cooled down my 8" Dob for a bit of observing. Having the moon out I knew that nothing DSO would be really visible. I had a quick 1 hr out. I started wit the Beehive cluster (M44); a lovely cluster with spread out stars. It fitted nicely in my 25mm EP. I then moved to Sirius, and I think I managed to split it with my 8mm; I could see two stars next to each other blinking (sorry if i used the wrong terminology). I then moved to Mars to see what Perseverance was up to...not much reall

  45. This is 3.75 hrs on M106 with the dual Esprit 150 and ASI178 cameras. It clearly needs more data to reduced the noise and hopefully provide more signal to the outer arms, which appear to me to be disproportionately fainter than the inner core compared to other similar galaxies.

  46. Beautiful John, a "proper scope"!. If I may join the "gratuitousness".. I was painting the floor of my recently refurbished outside brick barn today, where my scopes live, so I had to move lots of stuff out, or up off the floor, while the floor paint dries: so I took a few pics of the FS128 while it had to stand outside, and a couple as dusk fell and the almost full moon rose.. Also, John, did you check out The Trap last night? I had an hour out and despite the brightness of the moon I was easily able to see the E&F stars with direct vision..the transparency here was very good

  47. I made the most of the clear weather tonight to take a look at a few double and multiple stars. I started in Canes Venatici with a nice easy one, alpha CVn - Cor Caroli. This is a very easy split, appearing as a double at 30x magnification, but quite striking with the brighter blue-white primary and yellow secondary. Since I was in the area, I thought I'd also take a look at the famously red star, La Superba, Y CVn. Finding my way was complicated by the lack of guide stars, everything being washed out by the moon. But I knew more or less where it should be and, sure enough, at low pow

My Skymax 127 az gti for some lunar imaging, still waiting for my black box for the laptop dew sheild so trying to get the imaging in before the dew sets in. The tripod is at its lowest position tonight as it is quite windy at times here and gives less vibration this way, I normally have it full extension when no wind.
