M15 in Pegasus



Scope: C8 f/10; Location: Del Mar, CA;  23 August 2005; Camera: Artemis285

Exposure: 10 x 90 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 Astroart. Channels were co-registered in Astroart. The 90 sec exposures were used as the main luminance with level adjustments and curves to bring out object detail and preserve core 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 Luminance Channel. Final Image size is approximately 1392x1040

This image was guided; North is up. The image was taken with fairly good conditions at a heavily light polluted site.   M15 is at a distance of about 33,600 light years. M15 is located in the constellation of Pegasus. It is one of the densest globular clusters in the Milky way galaxy. This means it has a small bright core that is difficult to resolve stellar detail within. This image replaces an earlier image that can be seen in the Archives here. Horizontal FOV is 15'

Image Center is approximately - Equatorial 2000: RA: 21h 29m 58s Dec: +1210'03"
