Scope: C8 f/6; Location: Dos Picos Park, Ramona, CA;  8 June 2005; Camera: Artemis285

Exposure: 8 x 120 sec Luminance exposure (bin 1x1)with Baader IR Block Filter; 8 x 60 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 IRIS. Channels were co-registered in IRIS. The 120 sec exposures were used as the main luminance with level adjustments and curves to bring out object detail. Final LRGB combine was done in Photoshop using Luminance Layering (or LLRGB).  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. The image was taken with fairly good conditions at a semi dark site.   M5 is one of the oldest Milky Way Galaxy Globular Clusters with a computed age of 13 billion years. It is at a distance of 24,500 light years from Earth. This globular cluster has an ellipsoid shape that is aligned roughly from upper left to lower right. This image replaces an earlier image that can be seen in the Archives here. Horizontal FOV is 25'

Image Center is approximately - Equatorial 2000: RA: 15h 18m 34s Dec: +0205'00"
