Description

First image worth sharing using my new TPO 8" f8 Ritchey Chrétien. I still have problems with my tracking, which could be flexure problems. That is why I have such short exposures.

Change log:

A: Initial release, processed entirely in StarTools.
B: Took the image in A and used ACDNR in PixInsight.
C: Reprocessed from scratch after noticing that A and B were very noisy.
D: Some curves manipulation on C to prepare it to receive color data.
