M57 with the LN300 video camera and the 150mm Newtonian on a Star Discovery AZ GOTO mount

The LN300 video camera was placed at the Newtonian focus of the Star Discovery 150P, f/5 Newtonian. The camera was connected to a Windows 10 laptop via a Digital Climax VCap303 capture card. 300 x 5s exposures of M57 were captured using SharpCap. 100 x 5s dark-frames were also captured. The best 240 exposures (20 min total exposure) were dark-frame corrected, registered, derotated and stacked in Deep Sky Stacker. The resulting image was post processed in Photoshop:

The live screen view was pleasing and shows that this is very suitable for viewing and sharing the view as an electronic, deep sky eyepiece.
