NGC 3198 (11-26-2010)


This galaxy in southern Ursa Major is about 35,000,000 light years away. Normally, I present galaxies in white against a black background. In this case, the waning moon was still 66% full and only about 20 degrees away from this galaxy. That's not the best condition for shooting a galaxy. But the camera was running. I could turn it off and go to sleep, or let it run and go to sleep. I decided to let it run on this object. The resulting image is noisy and does not show well at all in white on black. It's much better this way, black on white, and more of the galaxy is visible.

This is 38x4' with the Atik 16 through the AT8RC and the IDAS-LPS-P2 from the backyard in The Woodlands, TX.
