Description

First light with monochrome+filters imaging/processing. I think it went rather well!

Unity gain/offset -20c.

I also think unity might be too high of settings for my setup/skies for at least my L filter.

Adjustments to focal reducer are needed.

I will have do more testing.

Thanks for viewing!

Description: integrated proper calibration frames, different L data. (60s exposure instead of 120) Thinking the lower exposure would fix the bloating rings on stars like in verA.
