Scope: C8 f/6.2, Location: Laguna Mountains, CA 27 August 2005 Camera: Artemis285
Exposure: 11 x 180 sec Luminance exposures with IR block, 8 x 90 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). Selective sharpening with layer mask was applied to galaxy dust lanes. Brighter star sizes were managed with a light minimum filter applied with mask. Photoshop was also used to subtract background noise from the luminance channel. Color balancing and final touches were done in Photoshop. SGBNR was used to smooth remaining background noise on the final result. Final Image size is approximately 1392x1040.
