Scope: C8  f/8 Location: Blair Valley, Anza Borrego Desert, CA   29 December, 2005  Camera: Artemis285

Exposure: 10 x 20 sec  (2x2 bin) Luminance Exposure with IR block filter, 20 x 20 sec (3x3 bin) each 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. Curves and Levels were applied in Photoshop to optimize object appearance. 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 Luminance Channel. Final Image size is approximately 800x597.

This image was guided; North is up. The image was taken with somewhat poor seeing - short exposures with binning were used to minimize the effects of poor seeing.   NGC 1851 is at a distance of about 39,500 light years. NGC 1851 is located in the constellation of Columba.  Horizontal FOV is 19'

Image Center is approximately - Equatorial 2000: RA: 05h 14m 06s Dec: -4002'48"
