OK i have a conundrum i am, hoping you all can help me with. I use a flat box i created with three of these in it (4x4 square):
I was using software to control the scope and camera at the time, MaximDL, and everything else ran fine except the flats. Normally it works fine for doing ISO 800 or lower shots but last night i tried to take a series of flats at ISO 1600 and the pixel values were all over the place. Whats odd is it started at the max pixel values i wanted for the flats on the first shot but then shot up from there and then started pogo-ing all over the place. I am trying to take images at 65% of full well capacity. On my DSLR full well is 65,500 and 65% works out to around 42,000 or so. I try to get it in the 38,000 to 42,000 range most days. I have a Canon 60D (FS modded) and was using a LPR filer from Orion. I even reduced the time to minimum and STILL it showed the same issues. I managed to get good shots of M16 and M15 with it but the flats proved to be an issue and without them the images look awful. my scope is still setup and i plan to do more imaging tonight but hope to find a solution to the flats issue before then. What could be the problem here? i brought the battery downstairs to charge afterwards figuring it was low and it was. Could the battery life have caused this?
