First Image: Jan 20, 2006. Need to work on a few alignment and internal reflection issues. Exposure is 2 x 90 seconds with no darks or flats used.

Second image: Jan 22, 2006. Star shapes improved. Need to flock baffles to eliminate reflections. Seeing  very poor (~4.5 arc-seconds), gusty wind (10-15mph gusts), but decent wind immunity. Exposure is 1 x 20min (2x2 binned) with no darks or flats used.

Third image: Jan 23, 2006. Star shapes good, and flocking of baffles removed reflections from image. Seeing very poor at 6.5 arc-seconds in focus runs. Exposure is 4 x 20 minutes (binned 2x2) and calibrated with flat and dark frame.
