StuartJPP Posted August 28, 2017 Share Posted August 28, 2017 ...so pretty typical for UK imaging then Friday's weather prediction for Saturday night in and around Horncastle was clear skies, but as time got closer to crunch time, the clouds started forming, not only on the weather site but also in the skies. Since I haven't been out for ages I thought I'd set up anyway. I didn't expect it to be a great night for imaging, possibility of mist if it was clear, and it was quite warm so I thought that I'd abandon plans for a faint object and try to nail M31 instead. I still haven't imaged it properly since starting to use my Canon 6D almost 3 years ago. So setup was quite quick and easy, especially since I trimmed all my cables and routed them for no snagging about 6 months ago. Polar alignment was with PoleMaster and was a breeze, everything was just right, except that as soon as I was polar aligned, the cloud came in at around ~22:00pm. After about an hour of waiting, I managed to get about 7 semi-decent subs before the cloud once again came rolling in at ~23:45. Then another wait of about an hour and a half. So at about 01:30 it cleared up and I managed to get another ~25 subs of varying quality, they weren't too bad but certainly not great. Because the street lights have been replaced with LED ones I didn't use the IDAS LPS D1 filter at all, which is a first for me from this site. The subs were quite a bit orange but they corrected decently enough. Anyway, enough waffle. Here's my initial processing attempt. Baader modified Canon 6D Canon 500mm f/4 L IS @ f/4 32 x 300 second subs at ISO800 100 Bias 25 flats No Darks Avalon Instruments M-Zero PHD2 and QHY5L-II-M and miniGuideScope for guidingAPT for image acquisition, GOTO++, plate solving and dithering Thanks for looking and as always comments and criticisms appreciated.

MARS1960 Posted August 28, 2017 Share Posted August 28, 2017 Great M31 and a great setup too. I hope the one i'm working on (should hit 10hrs tonight) comes out as good. 1 Link to comment Share on other sites More sharing options...
Alien 13 Posted August 28, 2017 Share Posted August 28, 2017 Beautiful and a cracking image too. Alan 1 Link to comment Share on other sites More sharing options...
Barry-Wilson Posted August 28, 2017 Share Posted August 28, 2017 I empathise with your frustration. However you made a cracking Andromeda with the 2 hours of subs used. I particularly like the colour balance and detail and contrast in the dust lines. Super image Stuart. 1 Link to comment Share on other sites More sharing options...
Allinthehead Posted August 28, 2017 Share Posted August 28, 2017 That's a great M31 1 Link to comment Share on other sites More sharing options...

Uranium235 Posted August 28, 2017 Share Posted August 28, 2017 For 2 hours, that is pretty spesh. Gawd knows how good it would have been if all 6 hours was useable. You had pretty much the same night as me, a bit on/off... however tonight is looking much better.... get out there and fill yer boots! 1 Link to comment Share on other sites More sharing options...

Thanks, but I can't as we are back home now and it is work tomorrow I would have loved to have collected 6 hours of decent subs on this target...then I think it would have been done and dusted. It will be another few billion years before we collide so plenty of time left and I don't intend on changing my kit any time soon so should be able to add to it when the opportunity arises once more.

gnomus Posted August 28, 2017 Share Posted August 28, 2017 (edited) '6 hours ... [resulting in only] ... 2 hours of barely usable ....' Pull the other one Stu, that is a cracker. The colours are especially good. Edited August 28, 2017 by gnomus 1 Link to comment Share on other sites More sharing options...

Pull the other one Stu, that is a cracker. The colours are especially good. Probably should have said "barely 2 hours of subs semi decent subs" instead....I am quite pleased (and surprised) with the result to be honest....but would have been awesome getting 6 hours on it.
