Scope: Megrez II f/3.9, Location: Blair Valley, Anza Borrego Desert, CA, 3 June 2005 Camera: Artemis285
Exposure: 8 x 120 sec Luminance exposures (1x1) with IR block, 4 x 240 sec H-Alpha Exposure (1x1) 6 x 60 sec RGB exposures (2x2).
Processing: Images were captured Artemis Capture (as FITs). Aligned/stacked in Registax 3 and saved as FITS. Luminance, HA, and Color channels were scaled and rough color balanced in Astroart. Channels were co-registered in Astroart . The HA exposure was combined with the luminance to control star size on the larger stars and to enhance detail and contrast on the Nebula. Final LRGB combine was done in Photoshop using Luminance Layering (or LLRGB). Color balancing and final touches were done in Photoshop. SGBNR was used to smooth background noise on the final result. Final Image size is approximately 1040x1392.
