I took them about an hour ago, camera attached to the scope with the cover on, in my OBS, pitch black. It can't be light. I had a look at the histograms. In the "good images" pixel values ranged from 350-450, and the bad ones around 600-900. Had it set to "Medium" It's funny though, did a set of 32, the first 5 were good, then all bad. Did another 32, and the first 25 were good, another 32, and they were ALL good. So I kept going for another 15 or so, to make it to 100, and it has seamed to work... Don't think it built up, it was a bit random.
I had a look at the FITS header for both images, and the temperature was round about where it was set to (another annoying issue is the temperature wont stabilise) but anyway...I got my 100 files, so that's a start I guess.
