Before getting into the imaging it's valuable to note that ASI294MC-Pro was not recognized by SharpCap 2.9 forcing me to upgrade to v3.1. To benefit from live dark frame subtraction I had to pay for the pro version only to find the dark frame subtraction did not work properly. I noted this to the developer who has worked with me to fix the issue which I'm currently testing. Recently, clear skies have been the exception. The following images were acquired without the live frame subtraction with dark frames applied during Autostakkert processing.

Except for the exposure times all of the above images were averaged from 25 subframes using the following settings. Messier 22 was acquired using 8s images. The other three images were acquired using 15s images.
