NGC2903 - Barred Spiral Galaxy

Sierra Skies Observatory - El Dorado Hills, California

Even with 18 hours exposure, the light polluted skies (suburb of Sacramento) and poor flat-fielding has resulted in a slightly clipped image. There is a very noticeable difference between the resolution I'm getting with the 12" LX200R versus RCOS, Planewave, and other higher-end telescopes. My processing skills also need improvement.
