Telescope: Obsession Mirror: 25" f/5 Galaxy Optics Drive: AZ/ALT, StellarCAT ServoCAT with DSC Argo Navis Camera Equipment: ST-10XME Class 2 CCD, AO-7, Pyxis Field De-Rotator, TCF-S Exposure: Single 10 minute. Processing: CCDOPs, Photoshop 5.0 (Levels, Curves, Unsharp Mask) Location: My backyard in Ridgecrest, CA (Mojave Desert), 2600 ft. elevation, population 30,000 Date: 5/11/05 Comments: Looking north into skyglow. This was just a simple 10 minute exposure to see how the ST-10XME and Pyxis field de-rotator would handle a slightly dimmer galaxy with a fairly high field rotation. Showed the result to Gary Myers of StellarCAT and he pointed out that there is a 17th magnitude and probably an 18th or more magnitude star in the image. Considering the high light pollution level this is good news.
