Perkil8r Posted June 25, 2012 Share Posted June 25, 2012 Had a go at M31. Got set up to do a run of 30 subs, but clouds rolled in after just 3. So here goes, 3 subs 1min unguided ISO800 on st80. Darks the same plus 3 x flats. I think the light patch at the top is stray light from a street light nearby, will try again with a shield in place next time. At least I think I'm in the right place, and I think the alignment must be pretty good. Here it is in all it's uglyness: Link to comment Share on other sites More sharing options...
Rusty Strings Posted June 25, 2012 Share Posted June 25, 2012 Hardly ugly. I'm impressed that you're having a go at that time of night Link to comment Share on other sites More sharing options...
Tweedledee Posted June 25, 2012 Share Posted June 25, 2012 You bagged three galaxies for the price of one there. M31, 32 and 110. A bit more processing would probably bring out more fuzzyness in the other two and make M31 even bigger. Looks good. Link to comment Share on other sites More sharing options...
Perkil8r Posted June 25, 2012 Author Share Posted June 25, 2012 Now I'm awake again and looked at it with a fresh set of hayfever eyes, I am a bit happier. The nasty patch at the top is almost definately stray light from the street light. I have figured a way to stop that, so fingers crossed for clear skies tonight. 3 for the price of 2? I only see 2?

Tweedledee Posted June 25, 2012 Share Posted June 25, 2012 They are definitely in there Mike. 32 is a bit starlike and 110 is elongated and fuzzy. Link to comment Share on other sites More sharing options...
Guest Tweedledum Posted June 25, 2012 Share Posted June 25, 2012 MIke, Change the image to greyscale, bring levels together a tad, then do an unsharp mask at around 1.5 px. Filesize not enough to have a real go but this removes the unearthly streetlamp glow. Cheers Link to comment Share on other sites More sharing options...
Perkil8r Posted June 25, 2012 Author Share Posted June 25, 2012 Thanks Damian, I might have a play later. The main thing is (trying to take positives from the experience) I got the right bit of sky, it was in focus and the alignment seems good for 1 min subs, so I know I can play properly the next patch of clear sky that comes along.

Guest Tweedledum Posted June 25, 2012 Share Posted June 25, 2012 I dread to think how it would look if i had a go!, if you can shade that streetlight, then the other two galaxies will pop out, if you unsharp and make a new layer you can see them more clearly but the main image dies... More power to you for thinking of doing those after a long trip too! Cheers Link to comment Share on other sites More sharing options...
Perkil8r Posted June 25, 2012 Author Share Posted June 25, 2012 The trip was nothing to me, I am used to driving long distances but hayfever did make the night rather less enjoyable. I noticed after the cloud had rolled in that the light was bouncing off the primary so I rigged up a shield which worked a treat. Unfortunately the clouds never rolled past in time to try again. I couldn't see it on the camera screen since the image was very light all over, it's only once I adjusted levels that it came to light (pardon the punn) Link to comment Share on other sites More sharing options...
+Graham Posted June 25, 2012 Share Posted June 25, 2012 Mike For 3 subs that is a cracking pic. Cannot wait until you can get a full run at it. Link to comment Share on other sites More sharing options...
Brantuk Posted June 25, 2012 Share Posted June 25, 2012 M31's a harder target than most folks think. It's too easy to burn out the core and fail to catch the dust lanes cos it's so bright. That's a great effort Mike and I'm sure you'll have it cracked in no time Link to comment Share on other sites More sharing options...
Daz Type-R Posted June 25, 2012 Share Posted June 25, 2012 Looking good, even with the glow of the street lights. Still can only see one Messier object in there Link to comment Share on other sites More sharing options...
andyboy1970 Posted June 25, 2012 Share Posted June 25, 2012 Getting there, as Kim says keep on it as it is a tough target but its perfect for the ST80. Link to comment Share on other sites More sharing options...
Perkil8r Posted June 25, 2012 Author Share Posted June 25, 2012 Now I've figured the lamp was getting in the way I will sort that incase it clears tonight. Link to comment Share on other sites More sharing options...
BAZ Posted June 25, 2012 Share Posted June 25, 2012 Good effort there Mike, if it was easy, I would be doing it. Link to comment Share on other sites More sharing options...
andyboy1970 Posted June 25, 2012 Share Posted June 25, 2012 How does the dmk21 work out as a guide camera ? It works fine, much better than the old webcam. When I get my Obsy and pier finished I'll get some more time to play with it guiding. Link to comment Share on other sites More sharing options...
