Six hours of NGC-772

I spent last night making adjustments to my guidance system, with the imaging session running late into the night. I ran out of good targets to image for the time available, and decided to go back to a galaxy I have imaged twice in the past. This makes at least 3 years worth of two hour images to stack of this particular galaxy. At this level of detail, you can plainly begin to see the halo of small galaxies surrounding the lopsided NGC-772. Also visible is the distorted spiral arm which has been torn apart by tidal forces.

I hope to get some color to add later.
