This image is taken with a modded Canon 6D at ISO 1600. I took 4 frames of 4 minutes each at 66 inches focal length. There was still no snow on the ground here so contrast was pretty good (for Alaska). The scope is my home built 12.5 inch Newtonian on an equatorial fork mount. Guiding is done manually using a built in off-axis guider.
Owls were hooting off in the distance making this evening a very pleasant one.
