Interestingly the version I prefer is your last one without darks (less contrasty mottles), but it's maybe just a matter of black point. Thanks, no there was less noise = less noise removal = less mottle. With the cooled DSLR (well below zero) Ha seems to benefit from darks but ordinary images don't, probably an issue of temperature matching, but the noise really is very low. 2 Link to comment Share on other sites More sharing options...

Nice work Nige, how did you find out? nova.astrometry.net? @Stub Mandrel that last one of the Sadr region is great! Definitely less blotchy than the versions with the dark frames, there's still a slight grain running through it, not sure what the cause would be, but I'd be very happy with a shot like that! I've noticed some others on here swear by not taking darks, and just using flats and bias for their calibration frames, is that what you did?

No worries I saw another Bubble image with the lobster claw nebula in it, here on SGL I'm off sailing for a week tonight, bet its going to be clear and moonless for the whole week Nige.

Peco4321 Posted August 25, 2017 Share Posted August 25, 2017 Great bodes @jjosefsen, here's my attempt, no where near as nice but exactly same composition. Only 20 x 60 plus darks and bias, next time will go for more data, maybe 45 sec to make it sharper. 150p eq3-2 unguided canon 1100d 4 Link to comment Share on other sites More sharing options...
Art Gecko Posted August 26, 2017 Share Posted August 26, 2017 I managed to get nearly another hour on my Eagle Nebula last night, in between the clouds... Still found this one really hard to cut the light pollution from, but I'm getting more pleased with the results... So in total, this is 1 hour 44.5 minutes all in 30 sec subs, with darks and flats and 3 attempts at processing before I was anywhere near happy with it... well it's looking a lot smoother at least 4 Link to comment Share on other sites More sharing options...
Stub Mandrel Posted August 27, 2017 Author Share Posted August 27, 2017 My plan for last night was to get this, I saw it visually in a dob, but I couldn't find it for imaging Link to comment Share on other sites More sharing options...
Peco4321 Posted August 27, 2017 Share Posted August 27, 2017 I managed Stephans Quintet, Pleiades, double Cluster, m2, and some Nebula near Denab, and only came in at 02:45 as it's my wedding anniversary today so my wife would have been a bit mad if it had been an all nighter. Sort of processed a few so far and will update later. Currently about £50 down at Beverley races!! 3 Link to comment Share on other sites More sharing options...

Peco4321 Posted August 28, 2017 Share Posted August 28, 2017 Don't you just love that moment in DSS when you see the 1st image, then the improvement when levels are aligned etc, here's the difference on Saturday nights Double Cluster. 39 x 45 sec plus darks and Bias. May add flats later. 2 Link to comment Share on other sites More sharing options...
Peco4321 Posted August 28, 2017 Share Posted August 28, 2017 Another image from Saturday nights Deep Sky haul, M2, but not very happy with it, I think focus must have slipped a bit, anyway, here it is, only 15 lights plus darks and bias, 45 sec ISO 800. 3 Link to comment Share on other sites More sharing options...
Stub Mandrel Posted August 28, 2017 Author Share Posted August 28, 2017 These are mine from Saturday Night. Had a lot of problems. Imaging is harder in the 'real' dark, so only 11 subs each! Heart Nebula: NGC1023 & IC239: 2 Link to comment Share on other sites More sharing options...
Peco4321 Posted August 28, 2017 Share Posted August 28, 2017 Final image from Saturday, Nebulosity near Cygnus, usual sort of settings and images, quite happy with this. 2 Link to comment Share on other sites More sharing options...

Thanks ☺yes very keen fisherman ( www.fishynige.co.uk ) , we are Sailing the East coast, Ipswich, Aldeburgh, Orford. Nice dark sky's so far, great observing with the bins, laying on deck gazing at night. Hope to get some Milky Way shots from Orford in a couple of days time. Cheers.

Your editing it more subtle than mine, it looks more natural I think. What ISO were you shooting at? 2 Link to comment Share on other sites More sharing options...

Peco4321 Posted September 1, 2017 Share Posted September 1, 2017 Here's my attempt last night at the eastern end of the Veil Nebula, I think that's how you describe it. 50 x 45 sec ISO 800 plus darks and bias. Quite like the colour I've managed to draw out. First time at this object. 3 Link to comment Share on other sites More sharing options...
Art Gecko Posted September 2, 2017 Share Posted September 2, 2017 Had a little go at M17 the other night... only managed to get 38 mins though as it sits in a tight window from my garden, very low and close to the neighbours rooftops... Had man-flu all week so haven't bothered adding to it yet as seems like too much effort to carry the scope outside. 2 Link to comment Share on other sites More sharing options...
Stub Mandrel Posted September 3, 2017 Author Share Posted September 3, 2017 I was amazed when I saw M17 through a 250mm dob last week. The 'swan' part was very obvious, especially the 'eye'. 1 Link to comment Share on other sites More sharing options...
Nigel G Posted September 3, 2017 Share Posted September 3, 2017 Nice M17 @Art Gecko hope you get over your flu soon. I was looking for a target as far from the Moon as possible, IC1805 the Heart nebula fitted the bill and perfectly in frame for my 80ED. A misty evening turned to a clear night, dumped 12 because of moisture in the air, I tried wrapping a warm tea towel around the scope and changing it every 10 minutes for another warm tea towel ( 2 tea towels warmed down the front of my trousers to body temp ) No dew build up on the main scope. 20x240s + darks, flats and bias. ISO800 - EQ3, 1200D, 80ED. Cheers Nige. 5 Link to comment Share on other sites More sharing options...
Peco4321 Posted September 3, 2017 Share Posted September 3, 2017 That is beautiful @Nigel G, stunning. Love the technique for the tea towel warming. 1 Link to comment Share on other sites More sharing options...
Nigel G Posted September 3, 2017 Share Posted September 3, 2017 Just buzzing around the interweb at some pics, The Hubble Pillars of creation in M16. considering a light polluted back garden at about sea level with a tiny 80ED EQ3 and cheap DSLR they are visible, a massive crop of M16 and the famous Hubble image. Mines the one on the right Nige. 1 Link to comment Share on other sites More sharing options...
