  1. The Witches Head Nebula, I'm not entirely sure I like this process. I was imaging late in the season and quite low down in the muck..I found this one of the trickiest images to Process .I thought I'd post it anyway. I may revisit it next season.. Imaged with the 105 f1.4 Sigma lens and ASI2600MC. 120s exposures a total of nearly 4 and a half hours. Processed with Pixinsight and Photoshop. Thanks for looking Peter Shah

  2. Not often photographed, Polaris surrounded by Integrated Flux Nebula....Its surprising how much IFN is there. I took this remotely from Spain with the 105 f1.4 Sigma lens and ASI2600MC. 53x 300s unguided exposures a total of nearly 4 and a half hours. Processed with Pixinsight and Photoshop. Thanks for looing Peter

  4. Having read that some of the newer FF/FR's do a reasonable job with older SCT's I decided to give the old 8" LX200 a try with my SW 80ED 0.85 reducer/flattener - my thinking was that it could not be any worse than the coma I get from my 0.63 Meade 4000 FF/FR. I stuck the ASI2600mc on it not really expecting much but this is what I got.... 8" LX200 GPS on a wedge, SW 0.85 FF/FR, ASI 2600mc, 120 x 120s Bin 2 x2 Now this is a bit of a crop but only really for edges and framing but the fact is that the really ugly U-shaped stars which, on the 0.65s

  6. This has been an ongoing project, and might well continue a while longer. I've been capturing data from the 19th March to the 14th April with the ODK 12 rig. TBH, I'm not that happy wit the result as i think it's not up to the quality that I should be able to get with the rig I have under the sky I have. Never mind, here it is. 39x 600 sec Red, 36 Green, 42 Blue and 79 Luminance. Best 90% Sigma Kappa stacked in DSS with full calibration with the heavy post processing in AstroArt 7. This is quite a heavy crop as I had skewed alignment edges (Th

  7. Not the best result, it was low in the sky and creeping into the London LP. (Be glad to get back to my Astro campsite at Bortle 4). Tried taking Oiii and Sii but there was only a faint whisp of Oiii at Bortle 8, so I didn't use it. There was plenty in Sii so i combined that into the blue channel making this HaRGSiiB: Atik460EX and Skywatcher Esprit100 3 hours Ha (Baader 3.5nm) 30min Sii binned 35m RGB biined (in case the SHO didn't work out), but very little Green as it kept catching the clouds. Total (without the Oiii) just over 4 hours

  8. 102 exposures of M51 taken over 3 nights ending on April 15. Shot with a Hypercam 26c on a Celestron C6 with the Starizona Corrector III. Mount is CEM40 guided with Altair 60mm guidescope and 290 cam.

  9. This really was a pig to process and trying to get the right colour when there is so much Ha present, very little OIII and good amounts of SII. It took 4 full attempts in PI to get it right and I ended up processing it completely differently that I would other NB images. I ended up having to balance the channels with Pixel Maths in PI and finally settled on the HSO pallet, I am quite pleased how the stars came out. In this instance I think perseverance paid off and I don't think with my skies that I could achieve much better. Further info here: -

  10. 60x300s captured with my Canon EOS 1000D (modified), 200P and Celestron AVX. I think my star shape is improving. I made some further adjustments to the primary mirror clips and also dialled down the dither - reducing the aggressiveness and allowing it more time to settle. Last night was also my first attempt at a scheduled meridian flip which was amazing to watch! I really do like N.I.N.A. I did however notice that although my guiding in RA was consistent on both sides of the meridian my guiding in DEC was noticeably worse after the flip. Any ideas?

  11. MY NEMESIS!! Jeez, this 3.5 hours of data has given me so much grief. First galaxy with the 269c pro TEC and I'm impressed, given how far away it actually is!! Have been troubleshooting for around a week! Bad flats, bad darks, light leaks, software problems, old snail's pace laptop causing issues. Nearly gave up. I didn't, so here is Messier 101 aka The Pinwheel Galaxy ๐Ÿ™‚ Stacked in DSS, stretched and LP removal in APP and then Photoshop. 37x180s 26x240s plus darks and flats. I could've pushed the subs to 300s though. Skywatcher 72ED, 0.8 reducer/flattener, 269c pro TEC

  12. Finally managed to get enough data to make a decent image. The full moon and low altitude didn't help much, but I'm quite pleased with the result. Need a few more hours of Lum to bring out more detail. 5 hours each of RGB 3 hours of Lum. Brian

  15. Having cracked my auto-focusing issues I thought to try an object not too impacted by the moon. I'm rather please with the little galaxy to the left (its always the little things ๐Ÿ™‚). This was 3.5 hrs of data so I may get some fainter detail when my processing improves. This was the first night I have used NiNA, with fully automated focusing and meridian flip. The scope also auto-parked and the camera shut down at the end of the session. This software is so good, I was more than happy to make a contribution to encourage its further development.The image is one of the most detailed I h

  17. It was my first time using N.I.N.A and autofocus with the ZWO EAF last night. I managed to get 24x300s on M63 with my 200P and Canon 1000D. I'm looking forward to collecting more data on this galaxy to really bring out the detail.

  18. I struggled a bit with the background on this one. It seems if I do any noise reduction at linear stage with data fro the 2600mc, I end up with nasty red blotchy background. So this is just a gently TGVD after stretching. SW Evostar80ED, NEQ6, ASI2600mc 160 x 120s Suggestions for improvement appreciated.

  19. Imaged on 9 April from my back garden outside Galway. This is 120 x 120s (Bin 2x2) taken on the 8" LX200 GPS on its wedge using the Skywatcher 80ED 0.85 reducer giving a platesolved FL of 1976mm with the ASI2600mc.

  20. I thought I'd stack what I had - current around 3 hours. I want to add another 3. I'm just getting used to the new scope. I also decided to push the gain a bit to allow for less imaging time (BST + Work). Hoping a bit more data will give it some more "pop". I was usimg 5 minute subs and Starlinks killed around 10, which was massively annoying!

  21. After weeks of crap weather or clear skies only when the Moon was up, I finally managed to finish my first image since January. It is an LHaRGB image of the intermediate spiral galaxy M106 in Canes Venatici. I started the project in March in the run up to 1st Qtr Moon, but the ~8 hours of LRGB data that I captured proved unusable, so I shot all that again over the past week, or so. The Ha data captured in March seemed to survive ok despite the bright Moon, so I've used that. Total integration is just over 15.5 hours, comprising L=31x10m, Ha=19x15m, R=24x5m, G+B=22x5m each.

  23. Hi all, comet 2020 R4 Atlas imaged from my back garden observatory on the outskirts Stoke-on-Trent. It is just one single exposure of 80s as it is moving quite fast, taken in the early hours at around 2-15am on 2/5/21 in poor conditions. Scope, OOUK ODK12 Camera, A A 294C Protec.

  24. Hi all, new to the site and new to the world of imaging with Newtonian's. I've done some imaging in the past with a 102mm doublet, but i recently purchased a 10" Quattro and boy was it a steep learning curve coming from a small refractor. So here is my 1st attempt at imaging with a Newt, and it still needs a lot more data to bring our the detail in the arms. Masked stretch in pixinsight messed up the cores of the bright stars, so i still have that to fix, but it's a start and i'm fairly happy with it as a 1st attempt at imaging with a newt.

  25. Ok it's another Whirlpool Galaxy shot. Taken over a period of a couple of weeks at the beginning of April, I managed to get an integration of: Lum 58 x 180s Red 61 x 180s Green 60 x 180s Blue 59 x 180s Total time 11.9 hours Main reason for it taking a couple of weeks is that auto focus was playing silly beggars and Ekos kept quitting when left to run after I went to bed. Ended up ditching well over a hundred subs ๐Ÿ˜ฑ Looking close in I was surprised ant the number of tiny galaxies scattered around.

  27. Good Evening All, After a nice streak of clear nights but not many narrowband targets about, at least not in my field of view from my garden. I've never been fully taken by the Wizard nebula, not in the same way as with the Jellyfish or the Rosette. But after a significant amount of imaging time it has started to reveal it's secrets. Total integration time 24.75h 143x 300s Ha 92x 300s Oiii 62x 300s Sii This shows the fainter details of the Ha around the nebula itself. Feedba

  34. The last few nights have been about learning the ASiair. It's exceeding my expectations, although there are some bits I'm finding a bit of a struggle. I managed 200 minuties on M51 over 2 nights. I had hoped to fight the moon and get some more tonight, but we have a thick sea fog (honestly it's like an episode of Scooby Doo out there). Here it is: Interestingly the Amp glow on the 294 ha really flared up. I did shoot a new set of bias frames (100 based on something I read somewhere) and this seems to have tipped the scales.

  36. Well we have had a run of clear nights with very little moon, so it has allowed me to build up quite a few subjects to process, the latest being M44 Beehive Cluster. To some it may seem boring or not of much interest, to me it is just another wonder of the universe that this collection of stars should gyrate together. Captured with my Esprit 100, Altair 26c, iOptron 40ec, Pegasus UPB, ZWO OAG, Lodestar x2 Guide Camera, this was mounted outside of my Observatory on one of iOptron heavy weight Piers.

  38. I have been quite fortunate with clear skies as I have about 5 or 6 subjects to process, but very little time due to my wife's deteriorating condition, so once she is tucked up for the night I can image away without neglecting her. Makarian's Chain. This has turned out quite well and shows just how many galaxies are in a tiny part of the the universe, I'll upload an annotated image showing just a few of the galaxies, each one containing billions of stars and comparable to our own Galaxy the Milky Way.

  41. Hi everyone, had a good session last night imaging different objects from my obs in Stoke-on-Trent. These two pictures[from my two rigs] are of the Nova in Cassiopeia which i last imaged on the 25/3/21. What a difference it has suddenly undergone in magnitude these last few days,by at least 2 i believe. They say it could be visible from a dark location with unaided eye now, had a look last night but not from my local. 1st pic taken with my wide rig WO STAR71mm,1st gen / ZWO 1600mc 1x180s.. 2nd was taken with my OOUK ODK12 / A A 294C ProTec . 2x180s.

  43. This is the result of the last three nights imaging - had the mount set up and aligned in the garden for the week, and NINA was generally well-behaved. So much easier when you don't have the hour of set-up time to do every night - just power up, cool down and press go. My only issue was with ASTAP plate solving failing consistently in the sequence, when it works perfectly when I run it manually in NINA. Luckily astrometry.net works great every time. Managed quite a few automated meridian flips too! I've got Bortle 8 skies, with a 3/4-to-full moon so plenty of LP and noise in there.

  44. I found myself one night having just completed another target and with no moon puzzled as to what to image as I don't like to waste nights like this. So for fun I thought I would aim at Polaris, that being a star from which all my Astronomy photos start from, I had heard lots about dusty lanes being visible from dark sites and indeed my mate Peter Shah has just published one he took from a true dark site, but for me in Bortle 5/6 skies this was my best attempt. Now for anyone contemplating this, you are going to find that your equipment is not going to function as norma

  47. This was my second effort with the SW FF/FR (0.85) on the LX200 and from the coma correction perspective I'm really pretty happy with the result - this was a very slight crop just for dithering edges and there is essentially none of the awful coma I was getting with the Meade 0.63 (see bottom jpg). The stars are still not perfect but I think another mm on backspace may sort that, then it will just be down to tightening up on guiding. The image itself is could be better - high haze has meant that I have struggled to show much of the outer ring but maybe I'll get a clearer night to g
