Last night I was running a dark and bias series and Something Happened. Normal 2x2 bias until the next one came through with horizontal streaks. All following 2x2 bias show this same streaking. Attached is a cropped example; streaking extends all the way across the image. 1x1 bias is saturated all the way across. Crop is attached. .4 sec darks show the same - 1x1 is saturated, 2x2 is streaked. Light frames are normal; nothing unusual. All of this behavior continues this morning - seems stable. All of this behavior is the same regardless of software used to run camera - Maxim DL, CCDOPS, or Sequence Generator Pro. Computer is Win7 Pro. Camera drivers and firmware are current. What broke?
