Description

Comparison ZWO ASI183MC vs. ASI385MC.

Today equal conditions for both sessions.

This shows also the difference between theory and practice. Everyone says that a color camera should have f/x = 5x pixelsize. So for the 183MC it should be f/12 (2.4um) and for the 385MC it should be f/18 (3.7um).

Both pictures were made with f/25 and both should be undersampled. But this is not right. If I use a Televue 2.5 (gives f/12.5 and should be the optimum for 183MC) both results are much worse.
