Description

First image guided with the QHY5L-II and Orion Thin Off-Axis Guider. Still working out the bugs in the setup. Also, I had to crop the image since I had some vertical bands in the images; I don't know where they come from.

Image Changelog:

A: Initial Release.
B: Used BackgroundNeutralization tool in PixInsight to remove the color cast in the background.
C: Increased saturation level.
D: More saturation using Velvia in darktable, added logo. Less blue in the cluster core.
