Another test last night with my new ZWO EFWmini filter wheel.

Shot from a light polluted location so background was severely compromise. However the EFWmini and SGP worked great. I'm ready for a trip to a dark site now and using this automation might get a few naps during the night!

Used my Baader TurboFilm cover over lens to keep out pollen - still tweaking the mounting for the film so it doesn't create optical artifacts (stars are a little wonky). I think I have it stretched slighly.
