A good, if short night. Seeing was variable, sometimes pretty good, other times choppy. I used the 20-inch for some observations, but was mostly masked to 7-inches. Continued the CDSA lightly physical list. I was a bit tired, and seeing wasn't getting any better, so wrapped up after an hour.

HO 399 AB: 178; 150x: Could not see B at first, so used full 20-inch aperture to find it and notice the position angle, through the star images were distorted.
