Description

550 60 secs unguided subs taken during the nights of 4th, 5th and 6th of August with a Newton 250 F 3.9 Orion, a QHY183 cooled on top of a Ioptron CEM60EC. Baader o3 filter was used.

Aquistions were disturbed by several passing clouds and 2 unwanted and annoying automatic windows restart due to windows 10 automatic update. Anybody here nows how to stop DEFINTELY windows update ? I have a fanless small pc that I use only for aquisition. I don't need any update. I can only postpone for 1 month or 2 but at the end it does the reboot automatically.

Stacking and processing (very little processing, just crop and a soft gradient removal) with Astroart. Very faint object. In the 60 secs single sub it was possible to see just a soft shadow.

Abell 61 is a very faint planetary nebula in the Cygnus constellation.

Thanks for looking.
