Image was taken as discussed below and heavily processed to reduce noise.
Image is a median stack of thirty-three 32 second exposures. I used frozen batteries in the air-cooled Olympus C2000Z camera to help reduce noise as the temperature in Florida was a comfortable 60 degrees. 31mm Nagler was used on a 20 inch Starmaster with GOTO Skytracker. Skies were somewhat hazy. Hope to do better under more transparent skies here in PA during the winter.
Image below is a sum stack of thirty-nine 32 second exposures. The vertical line must have been caused by a very slow moving satellite passing between the Horsehead and NGC 2023. The two short satellite trails seen here resulted after summing two 32 second exposures, each having one trail. Also the length of time between exposures....gap in the trail....was about 30 seconds to help cool off the camera to reduce noise.

Saturn:
Olympus C2020Z was used along with a Televue 2X barlow and Meade 8.8mm Superwide eyepiece.
