Carastro Posted April 2, 2021 Share Posted April 2, 2021 (edited) Imaged from SE London during the full Moon as was fed up with not having done any imaging for ages due to rubbish skies. Also wanted to try to get something before all the nebulae finally give way to galaxy season. It always seems to be clear when there is a full Moon, plus my location being Bortle 8 it is inevitably noisy. Imaged over 2 nights, Monday and Tuesday 29th and 30th March, I did take some Oiii and Sii as well but I could not usefully use them to enhance the image (maybe better skies would have done so), plus I had to throw away quite a few of the RGB because of heavy gradients, both due to the Moon and when the target was getting into the London sky glow. I imaged this target once before - 3 years ago with my SW130PDS but did not get the fly in that image. I see I had the same problem then with Sii and Oiii. Orientated this way I can finally see why they call this the Spider and the Fly. Skywatcher Esprit100 and Atik 460EX with Baader filters (Ha is 3.5nm) HaRGB Ha 23 x 600 (3h 50m) Red 6 x 200 & 4 x 150 binned (30m) Green 5 x 200 & 3 x 150 binned (24m) Blue 6 x 200 & 4 x 150 (30m) Total usable imaging time = 5hours 14mins Edited April 2, 2021 by Carastro 9 Quote Link to comment Share on other sites More sharing options...

At least Cygnus is now rising in the East just after midnight., providing you have a nice view East. Brian 1 Quote Link to comment Share on other sites More sharing options...
Carastro Posted April 2, 2021 Author Share Posted April 2, 2021 The beginning of the evening was not so bad especially on the 2nd night as the Moon didn't rise until 10pm, and then was behind the houses for a bit, but by about 11.30 onwards the target had definitely drifted into the London LP. 4 hours ago, AstronomyUkraine said: At least Cygnus is now rising in the East just after midnight., providing you have a nice view East. Unfortunately I can't see it until it has risen over the house tops a good 45 degrees or more up, so have to wait some time yet.

LP in the West, restriction to the East. Brian 1 Quote Link to comment Share on other sites More sharing options...
Bob-c Posted April 2, 2021 Share Posted April 2, 2021 That is a good pic Carole considering your location. Bob. 1 Quote Link to comment Share on other sites More sharing options...

Brian Also a bank of trees to the South, and next door's tree that obstructs Orion etc for about 3 hours per night, as you say, not good at all. Thanks Bob.

P Holdsworth Posted April 3, 2021 Share Posted April 3, 2021 Lovely image Carole especially given the LP and obstructions. I too can can see the spider and fly !! I wonder who it is that actually gives the nebulas their nicknames ? Paul 1 Quote Link to comment Share on other sites More sharing options...

MarkAR Posted April 5, 2021 Share Posted April 5, 2021 Amazing that you can get such great results with B8 skies and Blobby to contend with. Lovely image. 1 Quote Link to comment Share on other sites More sharing options...
Carastro Posted April 5, 2021 Author Share Posted April 5, 2021 Thanks Mark, well it makes the processing probably more difficult than if I had good skies. Carole Quote Link to comment Share on other sites More sharing options...
paulgrover68 Posted April 6, 2021 Share Posted April 6, 2021 Great image - I like how there's so much going on in that target - it's all very subtle and captured well, 1 Quote Link to comment Share on other sites More sharing options...
