Description

My first light with Redcat 51 and with my Zwo ASI183mm. This is a mono image with a view to add colour data with my 183mc later. Slight problem with amp glow, which could be a PHD2 issue and a small artifact in fat stars from processing.

Description: Processed with the latest version of Startools, the bug causing artifacts in stars during noise removal has been fixed. I think overall this is an improved processing effort.
