M92 in Hercules



Scope: C8 f/10; Location: Del Mar, CA; 23 May. 2006; Camera: Artemis285

Exposure: 12 x 120 sec Luminance exposures with UV/IR Block Filter, 7 x 60 sec RGB 

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 was removed 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). G2V color correction 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. The image was taken with somewhat good seeing.  M92 is a second well known Globular Cluster in the constellation of Hercules - M13 being its better known big brother. M92 is at a distance of about 26,000 light years from Earth.
