Scope: C8 f/5.8; Location: Del Mar, CA;  26 February, 2006; Camera: Artemis285

Exposure: 10 x 60 sec Luminance exposure (bin 1x1)with Baader IR Block Filter; 10 x 30 sec RGB (bin 2x2)

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. Central Gradient removal was performed in Astroart. Channels were co-registered in Astroart. The 60 sec exposures were used as the main luminance with level adjustments and curves to bring out dim stars. Final LRGB combine was done in Photoshop.  Luminance Layering (LLRGB) was used  to bring out star colors. Color balancing and final touches were done in Photoshop. SGBNR was used to smooth background noise on the Luminance construction. Final Image size is approximately 1392x1040

This image was guided; North is up. NGC 2420  is an open cluster in the constellation of Gemini.  This image also contains some dim galaxies in the field. The magnitude 17.1 galaxy PGC1653184 can be seen as a fuzzy line at the extreme left edge of the image. Three fuzzy galaxies, PGC21421, PGC1654079, and PGC1653803, can be seen in the upper right corner. Horizontal FOV is 26'

Image Center is approximately - Equatorial 2000: RA: 07h 38m 24s Dec: +2134'27"
