Description

First attempt of M33 via the EdgeHD 8 f/10 setup and processing it in PI while a new PC monitor. The picture lacks more data due to f/10 but nevertheless almost no cropping besides the usual corners was done on it.

This time I also, for the first time, switched to a bin 2x2 camera setting to check if it might improve the overall quality of the pictures.

This also to see if the image would improve as hinted by astronomy.tools, CCD suitability and a post once read from Sara Wager about the influence of binning (https://www.swagastro.com/to-bin-or-not-to-bin.html)

*) A - Quick & Dirty first processing attempt
*) C - Second attempt, less hasty, with RGB channels "split, process and recombine" approach
