15 august 2019

Last night had better transparency than the prior nights, but only by a little. Still limited to about 12th mag for close pairs. Seeing was variable, but there were some stretches of truly excellent seeing, and the 20" put up great star images. Pointing accuracy was ok, mostly to the edge of the field at high power. I tried to stay within the same declination band to not move the scope around too much, and to sync with every star I confirmed -- which helped pointing. Still, there were so many stars to choose from. There were a lot of matched 10th and 11th pairs, almost a parade of them. I skipped over some fainter pairs.

HU 1279 AB: 20" 667x: very faint, some haze, but at best moments resolved to two points in the elongated haze.
