M82 in Ursa Major


Scope: C8 f/5 Location: Dos Picos Park, Ramona, CA 1/23/2004 Camera: ToUcam SC3

Exposure: 15 x 18 sec, 12 x 50 sec Luminance Exposure with IR Block. 10 x 40 sec RGB Exposures.

Processing: Images were captured in K3CCDTools. Aligned/stacked in Registax and saved as FITS. Luminance and Color master frames were co-registered in Astroart. Luminance and Color FITS were combined in Photoshop with Luminance Layering. Star bloating was reduced with the 18 sec Luminance exposure. The 50 sec Luminance exposure had a good depth and galaxy details but suffered from a little star bloat. Color balancing and final touches in Photoshop.

This was a guided exposure. I think this image shows some reasonably good star depth as well as some of the dust lanes in the galaxy. Horizontal FOV is 16'
