Here is NGC 5907 in Draco. I got these images a little over a month ago but events have delayed my posting until now. It apparently has two common names. Full size image and exposure / processing details are here:

This object has a tidal halo surrounding it that R Jay GaBany captured in one of last year's APODs. My meager 2 hrs does not come close to catching any of those photons, but the galaxy comes through nicely.

Scope - C8 at f/6.4
Camera - Artemis285 IR/UV Block and RGB filters
Mount - G11/Gemini
Guiding - Megrez II at 1350 mm FL, DSI Pro, PHD Guiding

Jim,

This really came out great!
Nice details in the dust lanes and I like the overall color balance.

Nice shot Jim, good detail and color with an 8" SCT. So many targets and not enough time or clear (moon-less) nights.!

You got a really nice version. (That APOD must have involved some serious time and image stretching - too bad they don't report imaging and processing details.)

Thanks for the comments folks.

Charlie, R Jay did an image in 2006 where there is just a hint of the halo feature and he provided some exposure details on that image...
