Description

I used my ASI294MC Pro for color and the 294MM Pro for luminance could use more data and some Ha added (also didn't get flat frames to match some of the subs), but OK under the circumstances.  Here's the integration info:

Luminance: 140x2 minutes gain 120
RGB: 112x2 minutes gain 120

All images shot with the Optolong L-Pro light pollution filter
