Notes: Processing: Image acquisition with Canon EOS Utility. Calibration (7 darks, no flats), convert, align, and combine in ImagesPlus 3.0. Levels, curves, sharpen, resize, crop, and color balance in Photoshop. Star elongation is noticeable in several areas in the image. This was due to miscollimation of my FSQ, which has now been fixed by Texas Nautical Repair.

Ambient temperature was about 40°F. This is the first light photo for my 40D after filter modification by Hap Griffin.
