  1. This is SH2-86, which is a faint emission nebula in the constellation Vulpecula, close to the Dumbell Nebula. I took these subs while back, but just got round to finally processing it. I have a full set of Oiii and Sii too, but got hardly any signal from either, so in the end I decided to go moody black & white Ha 17x900s Ha, darks, flats and bias, equipment as per sig, Pixinsight processing I don't normally do starless, except for fun, but thought this one was rather striking: SH2-86 contains open star cluster NGC 6823 which is
  2. yay, I just got another Astrobin top pick !
  3. thanks all ! I've got over 2100 likes on Reddit for it ! Perhaps I should sell shares in it
  4. Seems to have turned into a bit of a multi-year project, this one - the original Ha was taken in 2017, though not nearly enough of it, and the Oiii and Sii in 2018, then I managed, pandemic notwithstanding, to add a lot more Ha to it: Has BBCode broken by the way ? SHO: Click for hi-res and a monochrome 2x drizzled Ha detail: Click for hi-res 9x 600s plus another 13x 900s Ha, 10x each 900s OIII and SII, darks flats and bias, equipment as per sig, taken in southern Spain, PI processing. This thread was my previous attemp
  5. For a while I thought I wasn't going to get any at all this year, because my kit is in Spain, but I did manage two weeks in the summer.
  6. decided to give this another go - having got my new monitor, I think the previous version was definitely looking a bit too saturated, so I've tried to bring that down. Also trying to get a bit more of a natural blue shell going round it, and I managed to integrate my RGB star colours better. What do you all think - better now ? Crescent Nebula (NGC6888) by Stuart Goodwin, on Flickr
  7. oo, I got a top pick in Astrobin - is that good ?
  8. Not quite the quality I'd normally want, since my kit is all in Spain and I'm not... But here's the Jupiter-Saturn conjunction on a smart phone from tier-4 London...
  9. Here's my latest homage to this glorious object... Swan Nebula (M17) SHO by Stuart Goodwin, on Flickr. Please click through for hi-res version. I took some Sii in the summer and added it to Ha and Oiii I'd taken in the previous year. 13x 900s Sii added to 17 each x 10min Ha and OIII, darks, flats and bias, equipment as per sig, processed in Pixinsight, taken in a dark sky sight in Spain. I've previously published an HOO version: Swan Nebula (M17) in bicolour HOO by Stuart Goodwin, on Flickr and an Ha monochrome detail: Swan
  10. thanks very much, and appreciate the cc - this one's a strange one, I like it on most of the monitors I see it, but on my main desktop pc monitor (which is admittedly past its best), I don't like it, looks too Disney. Santa's going to get me a new fancy colour-calibrated photo-editing-worthy monitor for Xmas, if he doesn't get locked down again before then. I don't think I actually saturated the nebula at all (well, maybe the blue)
  11. Yay !! My second astro image of the year - I'm on a roll now ! I added OIII data (22x 900 secs) to an earlier set of HaRGB data (22x600s Ha, 10x180s R,G and B 2x2 binned taken in 2017). Darks, flats and bias, equipment as per sig, Pixinsight. Most of the image is HOO,though I added in some RGB star colour, which I couldn't really get to sing very much (couple of red stars top-right I suppose) The Crescent Nebula (NGC 6888) is an emission nebula in the constellation Cygnus, about 5000 light-years away from Earth. It is formed by the fast stell
  12. Well Covid-19 put a massive dent in my imaging this year, since my kit is in Spain and it's been really hard to get out there. This is the first new work I've done this year, about 11 months after my last one. So... how is everyone anyway ? Here it is: Bubble Nebula (NGC7635) by Stuart Goodwin, on Flickr About 20 each of 900s Ha, Oiii and Sii, darks flats and bias, equipment as per sig, Pixinsight. I went for the (Ha, Sii+Oiii, Oiii) palette since I wanted something closer to natural colouring than the Hubble palette gives, especially since the different
  13. It was pinched optics in the coma corrector from being screwed on too tight (not that anyone cares, it seems ) Still not sure why the flats didn't pick it up though. Anyway, did a run of OIII on the Crescent last night, not a hint of banding
  14. jetting off on Friday, hoping to get a bit more imaging - quick nudge to see if anyone has seen anything like this before ? Cheers
  15. Apologies for bumping an old thread - Covid has meant that I've been locked down away from all my kit for most of the year - I hadn't actually imaged anything since October last year until I had a go last week. I've still got this banding issue unfortunately. I shot a new target, and could see the exact same banding pattern on my OIII and SII channels this time too. So that's three targets, all different parts of the sky and different times of the year, and all showing the exact same pattern in the exact same part of the frame as it comes out of the camera. My flats don't show the
  16. I had some success in testing in getting my laptop and a tablet to talk to each other using teamviewer by using my phone as a mobile wifi hotspot and both connecting to it, but to be honest haven't used it in the field - I think just the pain of setting it all up and worrying it would upset everything else on the laptop outweighed the lesser pain of padding outside every other advert break
  17. I've got another one actually - this one's a quintuple system in the middle of the Rosette: I think we imagers tend to capture them by accident though - according to Wikipedia, about 1/3 of the stars in our galaxy are multiple systems, so I've captured hundreds of them
  18. I did Albireo a while back too, but seem to have lost it. Here's one that a lot of us may have inadvertently got - Alnitak and its double:
  19. fair comment re the stars - I usually use a tone-map technique like this for merging my channels which gives the flat white stars as in my original image. It does give me headaches on the brighter stars around my newt spikes though. For the reprocess I actually borrowed some star colour from a previous DSLR image of mine - maybe it should be feathered in a bit more
  20. I agree, I do seem to lean to the dark and stormy side at the moment - must be typhoon season in the Lagoon
  21. Yes indeed, isn't that always the way ! Thanks for the nice comments all
  22. Ok, I know it's not the right season at all for the Lagoon, but I fancied a reprocess of this data. It was my first go at SHO narrowband, and I've got plenty of data, but my experiences processing narrowband since led me to think that I should be able to pull out much more detail than I had before, so here goes: 16 each of 600s Ha, Sii and Oiii taken over 3 nights in summer 2018, darks flats and bias, equipment as per sig, Pixinsight. For comparison, here's the first version and the thread on it: What do people think - improvement
  23. Only 3 photos for me this year (!), two of the below are detail shots, but I'm pleased with what I managed - loving my long focal length plus narrowband detail Rosette (HOO): Ced 214 (SHO) + detail: Swan (HOO) + Ha mono detail: Equipment as per sig
