latency testing

I finally got around to running a few trials of the latency test with the STL1001E CCD camera as described in MaximDL CCD software.

The result shows the delay from the time the computer tells the camera to open to when the CCD actually starts to register an image.

Surprisingly the delays ranged from 0.02 seconds to 0.09 seconds in 25 trials. The most common delay was 0.03 seconds. An average of 0.04 seconds is the delay that I ended up adding to the time in the fits register. So every image I take will now include this very minor adjustment to the U.T. start time.

The folks at SBIG did a really great job with their shutter system.
