M62 in Ophiuchus



Scope: C8 f/8; Location: Laguna Mountains, CA; 17 June 2006; Camera: Artemis285

Exposure: 8 x 90 sec (1x1 bin) Luminance exposures with IR Block Filter, 8 x 30 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. 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, Atmospheric Extinction 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 a guided image. M62 is located in the constellation of Ophiuchus - within  the Milky Way, so the background stars are rich. It is one of seven Messier Globulars in Ophiuchus. It is one of the most irregularly shaped globular cluster - it is somewhat elongated up as seen in this image. M62 is located at a distance of about 22,500 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: 17h 01m 13s Dec: -3006'42"
