Hopefully our luck is changing weather-wise, as there have been several nights of at least clear skies. Opened up the 20-inch in case seeing would cooperate, but it was poor at full aperture, so I masked down to 7-inches for the session. I've run out of targets in the 13-15h range on the CDSA list, except for the closest splits which would require better seeing. I'll spend some time learning how to use my Questar and trying to use the NV device on my 20-inch (more in-focus needed, so might need to rebuild the focuser board).

HLD 18 AB: 178; 280x: 3 Dm, difficult, can just detect B with direct vision, close to A, need magnification to separate. 16% PRO, 570 AU WS, 2.2+1.1 Msol, it is possibly binary and needs an orbit.

STT 281 AB: 178; 280x: Very fine light orange stars, very closely split, 2 Dm, B is a fine point of light. No Gaia parallax data for B, but an orbit should be tried.
