Seeing was very good but not spectacular. Due to neighbor's lights I pointed to the north after the first few observations so my back would be to the lights. There are plenty of pairs in Lacerta, Andromeda, and Cassiopeia, it's a very rich area. Seeing was good enough to go after some interesting short period pairs. Observed doubles from 9pm to 1am. Some dew, a little chilly. When I needed to slew more than a couple degrees after midnight I disengaged the drives and pushed the scope manually, so that I would only have a short, and quieter, slew to the target. I used the Disable Tracking command in SkyTools to get a more accurate estimate of the PA on the short period pairs, it helps a lot.

VYS 2 AB V547 Cas. Faint, very fine pair, seen at 205x and had a better look at 333x. Wide, ~4" slightly reddish faint stars. SkyTools brought this up as a short period pair, however it won't make a significant change in my time. It turns out A is also a pair, MCY 1 Aa-Ab, 10.8/12.5 0.5" with a period of only 15.59 years -- discovered by one D.W. McCarthy (no relation!) in 1989 during the first results of the Steward Observatory Infrared Speckle Camera using their 2.3 meter telescope. The Ab star has a mass of only 0.18 of the sun. I think it is gettable visually with the Challenger on a good transparent night, or with the Lick Great Refractor if I ever have the good fortune to observe with it.
