I was out giving the new camera (cooled and modded 1100D) a run on the Polarie this evening. And while it was doing it's thing, I thought I'd take another look at the test shot's I'd taken with it during Astrofest.
During camp, for some reason I could only get the camera to capture in Backyard EOS in "frame and focus" mode. So the images it was taking were only 15 seconds long, and shot in Medium Jpeg.
Soooo, I thought, what the hell, I'll stack 'em and see how it looks.
And here is how it looks.

5 x 15 second subs @ ISO3200
No flats, no darks.
