Scope: C8 f/5; Location: Del Mar, CA; 12 May. 2004; Camera: ToUcam SC3

Exposure: 15 x 10 sec Luminance exposures with IR Block Filter; 12 x 50 sec with Orion SkyGlo filter, 12 x 24 sec RGB 

Processing: Images were captured in K3CCDTools. Aligned/stacked in Registax and saved as FITS. Luminance and Color channels were scaled and rough color balanced in Astroart. Channels were co-registered in Astroart. The 50 sec SkyGlo filter exposure was used as the base Luminance channel. Luminance and Color FITS were combined in Photoshop with Luminance Layering. Color balancing and final touches in Photoshop. SGBNR was used to smooth background noise on the luminance channel and the final result. Resized to approximately 800x600.

This image was a guided image. I have not imaged this cluster prior to this image. Horizontal FOV is about 16'
