Dean Posted October 11, 2009 Share Posted October 11, 2009 Here is my attempt at the eagle nebula taken over a few nights last month. Image for M16 is a stack of 31x 60 secs at ISO 1600 using an unmodded canon 350 and a Equinox 80.My mount is an EQ5 with a synscan upgrade kit. The subs were taken after polar aligning with polefinder and using the mount to track. I bought the upgrade kit so I could start auto guiding but I am still having problems which hopefully I will sort out soon.Thanks Dean Link to comment Share on other sites More sharing options...
RichieJarvis Posted October 11, 2009 Share Posted October 11, 2009 Wow - looks pretty good to me for a DSLR widefield How on earth did you manage to image M16 this late in the year? Are you not in the UK?Cheers,Richie Link to comment Share on other sites More sharing options...
Deneb Posted October 11, 2009 Share Posted October 11, 2009 Not bad image there, your suffering from some Vignetting. Taking some flats will cure that problem. Or even better make a light box. Link to comment Share on other sites More sharing options...
Dean Posted October 11, 2009 Author Share Posted October 11, 2009 Thanks Richie, I live just outside Bath and south of Bristol. I had a slot of about half an hour between 21.30 and 22.00 and got the subs over a couple of nights when the weather permitted, as well as dodging neighbours bonfires!Cheers Dean Link to comment Share on other sites More sharing options...
Dean Posted October 11, 2009 Author Share Posted October 11, 2009 Hi Deneb,I have been thinking about how I could get over this problem by maybe using a two inch camera adaptor or would I still have to take flats? Thanks Dean Link to comment Share on other sites More sharing options...
RichieJarvis Posted October 11, 2009 Share Posted October 11, 2009 You will probably still have to take flats - the problem is that with a big chip like on a DSLR, you will find that the chip is not evenly illuminated unless you buy a very expensive scope.Guiding-wise - whats the problem you are having??Cheers,Richie Link to comment Share on other sites More sharing options...
Starflyer Posted October 11, 2009 Share Posted October 11, 2009 Nice image Dean and a tough target from the UK at this time of year Here's a thread showing my home made lightbox for my WO ZS80. Flats (and bias frames) will make a huge difference to your images as will auto guiding when you get that working. Link to comment Share on other sites More sharing options...
Cloudwatcher Posted October 11, 2009 Share Posted October 11, 2009 I'm not an imager I'm afraid,don't know nowt about bias frames or flats etc. but I know what I like.I like your image a lot being a fan of widefield views. If you have Photoshop installed you can reduce the 'clutter' quickly using Gamma reduction in the Exposure tool. I like a dark background myself (not everyones cup of tea) shows up the detail of the subject a bit better I feel.For what it's worth here is my view of you very creditable image.

Dean Posted October 11, 2009 Author Share Posted October 11, 2009 Guiding-wise - whats the problem you are having??Cheers,RichieI haven't really nailed the problem yet, I think it may be related to the backlash on my mount, but I am going to have another go at sorting it tonight. Thanks for asking. I will post an update on my findings but would be grateful if you have any ideas on the problem.Thanks Hi Starflyer, great thread - thanks for sharing it with me. I think I will have a go at that.Hi Cloudwatcher, great improvement, I like your view too.Thanks to you all Dean Link to comment Share on other sites More sharing options...
