This image was a result of an evaluation test of CCDNavigator and ACP Expert. At the time, I was also in the process of calibrating my new autofocusing software (FocusMax) and attempting to figure out why ACP was giving incorrect Pierside reporting information (now resolved). Due to these issues, I decided to image under non ideal (moon up) conditions. I was quite pleased with the result.

LIGHTS: 14 x 600s, DARKS: 30; BIAS: 100; FLATS: 40 all at -20C.
