NGC 2546 in Puppis



Scope: Megrez II  f/4; Location: Dos Picos Park, Ramona and Del Mar, CA;  8 March and 11 March, 2006; Camera: Artemis285

Exposure: 10 x 60 sec Luminance exposure (bin 1x1) (8/4) with Baader IR Block Filter; 12 x 30 sec RGB (bin 2x2) (11/4)

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 final result. Final Image size is approximately 1392x1040

This image was guided; North is up. NGC 2546  is an open cluster in the constellation of Puppis. Its distance from Earth is about 3,300 light years.  It is a rather Southerly target from my location and just skims my Southern horizon so the imaging conditions are challenging even for a bright open cluster such as this. Horizontal FOV is 96'

Image Center is approximately - Equatorial 2000: RA: 08h 12m 24s Dec: -3737'00"
