That's one target ticked as "done", aluminium print 40x30cm ordered.


Shot on my CG5GT/OnStep rebuilt, Skywatcher 130PDS, 450D modded & cooled, over 4 nights. 
162 Lights selected by hand amongst 300+ (mix of 90s, 120s and 180s), 25darks, 100flats, 100darkflats, 25bias. (stack: 5h 9mins) 
NINA for capture, then  stacked in Astap (using calibration matching), then stretched/flattened in GraXpert, then colour processed with Gimp. 

The printable version is SEVERELY cropped compared to the stacked FoV (about 1/5)

Of course it is not the best ever considering what some of you guys do, but I am still very happy with it. It will look great in my office/remote observatory above the computers.
