From ten days ago the California Nebula.

Well at least part of it! Around 28 good frames at 300 seconds each and for the first time initial integration thru the program Siril. I first was following a youtube video on using the program but felt the non linear functions were too harsh so I ran it again with the linear functions and then went to photoshop for the processing I am familiar with. This set used dithering on the light frames and a new flat frame set along with a bias set allowing Siril to do its thing with the whole bunch. Produced an initial integrated stack in just two minutes so that was impressive use of my main desktop running an AMD Ryzen 5 2600X Six-Core Processor 3.60 GHz and 16gig memory. The result seems superior to DSS images from the past, though I am now more convinced my coma corrector is lacking. The star spikes have a double edge to them which I am finding in the forums a weakness of the Baader 2″ MPCC Mark III along with the arrows near the edges.
