Horsehead Moon in H-Alpha Horsehead

Date: November 30, 2003
Exposure: 1 x 1/10 sec
Processing: PhotoShop Unsharp Mask
Conditions: Average
Scope: AP-155EDF @ f/7, CS 3nm H-Alpha filter.
Camera: ST-8XE/CFW-8A, -25°C
Comments: Took this while waiting for the darkness. The night was clear with no wind, but the temperature was stuck on 48°F and the previous night it had gone down to 25°F. I had to use water cooling to get the camera down to -25°C. This was the best of about 25 shots that I took.
