Image is a median stack of twenty-three 32 second exposures. I used frozen batteries in the air-cooled Olympus C2000Z camera to help reduce noise. 31mm Nagler was used on a 20 inch Starmaster with GOTO Skytracker. Ambient temperature was in the high 50's. Skies were pretty transparent but not very steady.
