Description

Data shot during back focus checks and Astro FocusCube setup. An attempt via PixInsight and the latest APP version, to not waste the data, despite being less than 1 hour total.

Again heavily cropped due to the huge amount of vignetting that apparently is a given fact using the ZWO ASI071MC (APS-C camera) and the Celestron 0.7 reducer despite the sales pitch on the Celestron webpages...

Description: According to my wife, the stars were a bit green ;-) so I made an attempt to correct this with, among others, SCNR in PixInsight. My new desktop screen showed me indeed a completely alternative version when I had a look at the old one. Definitely not as intended.
