We have 2 ST-8 cameras and a new computer. We installed CCDOps and tried to take an image. The shutter appears to move and we get a blank (0 counts) image. The second time, we get a Shutter Error message. This alternates (shutter moves with blank image followed by shutter error) with each attempt. We have the same issue with both ST-8 cameras, which leads me to think it's not actually a mechanical issue with the shutter. Has anybody else had this issue?
