This is a project I've been working on for a little while now. Image data collected across 9 nights. I actually collected quite a bit more data than this, which in the end provided greater flexibility in selecting subs with more optimal FWHM across each night. The image shown here comprises 4min subs only, however I also collected a series of 6min subs as well. After several trial runs I decided to stick with the 4min subs only as this resulted in much tighter stars. I have now acquired another camera and am keen to move onto other targets, so i have decided to draw this project to a close for now.
In part this was an experiment to see how much of the outer outer regions I could bring out with a humble DSLR. I'm pleased to see that some of this outer extended nebulosity is starting to show, however I think the signal gains from here (with a OSC DSLR) are incremental at best.
So, the final tally:
Camera: modded Canon 1000D
Scope: Vixen VC200L with f6.4 reducer
Exposure details: 203 x 4min subs @ ISO1600
