I didn't really want to voice anything about my issues, but I'm dismayed to say I've had a much longer period of various issues with my STXL11K. Peter and SBIG have been responsive, but I'm still not really happy, doing many tests to try and eliminate issues. In the last few months the camera has developed the same vertical lines I can see in these dark frames
[perhaps difficult to see in my attachment]. I was advised by SBIG to use a CCDOPs vertical filter to pre-treat my subs. But it gets extremely complicated to work on the data as what do you do for Flats, Darks and Bias frames? Pre-treat these too? That's hell of a lot of extra work. What to do?
