Description

Just checking out to see if an APS-C camera (ZWO2600MC) could work with my C8 RASA. The answer appears to be yes.

Really lousy night, but I had to try it out. Stars look good, corner to corner, edge to edge. Minimal vignetting, easily cured with flats + bias. Only 35 minutes total imaging time., this was just a test.

Have plans for the 3.3 X 2.2 degree field.
