Date: Jun 2,9,11 2008
Location: New Ringgold PA
Optics: Meade LX200R 12 inch at f/5.9
Mount: Paramount ME
Camera: SBIG ST-8XME / CFW-8
Guiding: ST-8XME integral guiding chip controlled by Maxim CCD
Exposure: LRGB (color 2x2 bin): Luminance: 12x10 min, R:8x5 min, G:8x3.3 min, B:8x6 min
Processing: Image acquisition using CCD Autopilot. Chris Abissi did a great job of processing this for me. His resuults were so superior to my own that I am only posting his image.
Comments: A large but faint galaxy. Chris' careful stretching of the spiral arms accentuated the red-magenta nebulas and the young blue star clusters while capturing the warm yellow glow from the old stars making up the core.
