Scope: C8  f/3.1, Location: Blair Valley, Anza Borrego Desert,   3 June 2005  Camera: Artemis285

Exposure: 6 x 180 sec Luminance exposures with IR block, 6 x 48 sec RGB exposures.

Processing: Images were captured Artemis Capture (as FITs). Aligned/stacked in Registax 3 and saved as FITS. Luminance and Color channels were scaled and rough color balanced in Astroart.  Channels were co-registered in Astroart . Final LRGB combine was done in Photoshop using Luminance Layering (or LLRGB). Photoshop was also used to subtract background noise from the luminance channel. Color balancing and final touches were done in Photoshop. Minor star repair was made on edge stars which otherwise experienced some coma .  SGBNR was used to smooth remaining background noise on the final result. Final Image size is approximately 1392x1040.
