Last night I was trying to take some images of the lunar eclipse through my STXL16200, and the shortest exposure I could take (using CCDOps version 5.66 Build 1) was 0.18 seconds. Not that this would have made any difference for the lunar imaging, but the specification sheet on the web site states that a minimum exposure of 0.12 seconds is possible. This discrepancy should be corrected on the specification page. I was finally able to get some images that were not totally washed out after putting a mask over the front of my objective.
