M68 in Hydra



Scope: C8 f/8; Location: Del Mar, CA; 13 June 2006; Camera: Artemis285

Exposure: 12 x 180 sec (1x1 bin) Luminance exposures with IR Block Filter, 7 x 90 sec (2x2 bin) 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 1386x1040.

This image was a guided image. M68 is located in the constellation of Hydra- well outside the Milky Way, so the background stars are sparse.  M68 is located at a distance of about 33,000 light years from Earth.  This image replaces an earlier image that can be seen in the Archives here. Horizontal FOV is about 20'

Image center is approximately - Equatorial 2000: RA: 12h 39m 28s Dec: -2644'32"
