Observed with the 20-inch but masked down to 7-inches for most of the night due to seeing. I was able to go after a couple of challenge movement pairs at the end of the night. Average transparency.
STF1559 AB; 178; 140x: Pretty white stars, 1 Dm, close but comfortably split. There is no parallax range overlap, -49%, it is not binary.
11h 38m 49.11s +64° 20' 49.4" P.A. 326.00 sep 2.0 mag 6.81,8.01 Sp A5IV dist. 210.97 pc (688.18 l.y.)
STF1567 AB; 178; 140x: >2 Dm, pretty close around 2" separation. There is 31% parallax range overlap, only 824 AU weighted separation, 1.7+1.3 Msol, so it is possibly binary and needs an orbit.
11h 42m 58.94s +64° 21' 19.4" P.A. 84.00 sep 3.6 mag 9.35,10.50 Sp F5
STF1407 AB: 178; 140x: Faint near equal pair, well split. There is 40% overlap of the parallax ranges, 857 AU weighted separation, 1.3+1.1 Msol, and the radial velocity delta -0.4 is less than the escape velocity 2.2, an orbit should be tried.
10h 09m 01.98s +64° 26' 40.6" P.A. 51.00 sep 4.9 mag 10.17,10.63 Sp K7 dist. 176.06 pc (574.31 l.y.)
STF1398 AB: 178; 140x: White and significantly fainter 3 Dm B, pretty closely split. There is no parallax range overlap, -96%, it is not binary.
10h 01m 32.06s +68° 43' 05.1" P.A. 102.00 sep 4.1 mag 8.09,11.39 Sp F0 dist. 159.24 pc (519.44 l.y.)
STF1400 AB: 178; 140x: In same filed as STF1398, faint pair, pretty closely split. There is 76% overlap of the parallax ranges, only 243 AU weighted separation, 1.3+0.8 Msol, and the radial velocity delta 1.9 is less than the escape velocity 3.9. It is likely binary and needs an orbit.
10h 02m 56.49s +68° 47' 09.3" P.A. 225.00 sep 3.6 mag 8.02,9.77 Sp F5 dist. 61.73 pc (201.36 l.y.)
STF1415 AB: 178; 140x: AB is a pretty 1Dm pair of bright stars, very light yellow A and light blue B. C is one of the widely separated faint stars in the field. AB has 75% parallax range overlap, 2,024 AU weighted separation, 2.3+2.0 Msol, and the radial velocity delta 0.8 is less than the escape velocity 1.9, it is likely binary and needs an orbit.
10h 17m 50.61s +71° 03' 38.9" P.A. 168.00 sep 16.5 mag 6.65,7.27 Sp A7m+Am dist. 401.61 pc (1310.05 l.y.)
STF1508 BC: 178; 140x: Faint trio of near equal stars, though one is fainter needed 200x to see plainly. BC is actually has the closest separation, AB and AC were measured originally but I don't know why because they are very wide. There is 3% parallax range overlap, though with 3% error, 3,372 AU weighted separation, 1.4+1.3 Msol, and the radial velocity delta 0.4 is less than the escape velocity 1.2. Marginal to be binary, but an orbit should be tried in any case.
11h 08m 33.82s +68° 24' 40.4" P.A. 243.00 sep 8.6 mag 10.41,10.86
STF1418 = HJ 3324 AB: Faint pair, <1Dm, well split. There is 18% parallax range overlap, 6,057 AU weighted separation, 1.8+1.4 Msol, but the radial velocity delta 1.8 exceeds the escape velocity 1.0, so it is not likely binary.
10h 20m 23.83s +68° 08' 20.3" P.A. 199.00 sep 18.6 mag 9.95,11.04 Sp K2 dist. 183.82 pc (599.62 l.y.)
STF1498 AC: 178; 140x: BU 1430 AB is >1 Dm, wide, B brightens with averted vision. AC is a wide pair, surprising Struve missed AB. Surprisingly, there is no parallax overlap for AB -80%. AC has 8% parallax range overlap, but a wide 7,751 AU weighted separation, 2.7+1.2 Msol, but the radial velocity delta 2.9 far exceeds the escape velocity 0.9, so it likely is not binary either.
11h 01m 35.83s +66° 26' 59.1" P.A. 13.00 sep 8.6 mag 7.95,11.41 Sp K0 dist. 320.51 pc (1045.5 l.y.)
STF1514 AB: 178; 280x: Nice close pair, faint need higher power to get a nice split, 1 Dm. 10% parallax range overlap, 367 AU weighted separation, 1.9+1.4 Msol, so there is some chance it is binary and an orbit should be tried.
11h 11m 38.55s +66° 06' 48.0" P.A. 342.00 sep 1.3 mag 9.49,10.64 Sp F2
STF1469 AB: 178; 140x: >1 Dm, wide. 74% parallax range overlap, 892 AU weighted separation, 1.5+0.8 Msol, but the radial velocity delta 2.4 is slightly more than the escape velocity 2.2. There is a slight chance it is binary and an orbit should be tried.
10h 47m 43.86s +65° 27' 36.4" P.A. 324.00 sep 10.9 mag 7.74,10.42 Sp F8V dist. 86.88 pc (283.4 l.y.)
STF1550 AB: 178; 140x: 1 Dm, wide. There is no parallax range overlap, -97%, it is not binary.
11h 34m 39.80s +63° 38' 35.9" P.A. 41.00 sep 18.1 mag 8.93,11.13 Sp G0 dist. 68.12 pc (222.21 l.y.)
STF1444 AB: 178; 140x: GT UMa. >1Dm, wide. 77% parallax range overlap, 3,488 AU weighted separation, 2.2+1.1 Msol, but the radial velocity delta 10.2 far exceeds the escape velocity 1.3, it is not likely binary.
10h 35m 55.66s +63° 35' 32.4" P.A. 266.00 sep 17.9 mag 8.17,10.72 Sp F2 dist. 145.77 pc (475.5 l.y.)
STF1513 = H 4 106 AB: 178; 280x: Faint B needed high magnification to see, well split. There is -22% parallax range overlap, it is not binary.

STF1512 AB: 178; 140x: Equal white stars, well split. Thiere is no parallax range overlap, -86%, it is not binary.

STF1491 AB: 178; 140x: Faint B seen with averted vision, then can hold direct, well split. There is 57% overlap of the parallax ranges, 4,287 AU weighted separation, 2.7+1.2 Msol, but the radial velocity delta 3.8 exceeds the escape velocity 1.3, it is not likely binary.
10h 58m 50.42s +61° 42' 56.4" P.A. 33.00 sep 14.1 mag 8.39,11.33 Sp K0 dist. 1052.63 pc (3433.68 l.y.)
STF1519 AB: 178; 200x: Lovely pair, half delta mag, split at 140x but better at 200x, close, a bit more than 1" separation. There is 53% parallax range overlap, 306 AU weighted separation, 1.8+1.4 Msol, so it is likely binary and an orbit should be tried.
11h 15m 36.65s +59° 46' 43.4" P.A. 289.00 sep 1.5 mag 9.03,9.95 Sp F5 dist. 250.63 pc (817.56 l.y.)
