Description

Reprocessed an image of 2017. 232 60 secs unguided exposures done with an RC8 at full focal length, a QHY174 mono, on top of a GPD2. Image was very noisy. It was one of my first time using the QHY174 and didn't manage correctly the cooling. Also no darks was used (which are mandatory for this kind of camera). Acquisition and processing with Astroart. Cosmetic with Photoshop.

Thanks for looking.
