A night out with my 6-inch, after a month of cloudy weather. I had some difficulty getting the setting circles to align, and conditions were not very good -- poor transparency and average seeing, even with the small aperture -- and I had a late start as it was. Good to be out all the same.
A 2142 AB: 152; 250x: Faint unequal pair, hairline split. -14% PRO, and a poor PMV, it is not binary.
10h 05m 43.55s +41° 02' 42.7" P.A. 293.00 sep 1.0 mag 7.97,8.83 Sp F0 dist. 137.55 pc (448.69 l.y.)
BU 219 AB: 152; 250x: Excellent close pair, 2 Dm, nicely split, best seen with high power. -23% PRO and a poor PMV, it is not binary.
10h 21m 35.86s -22° 31' 42.7" P.A. 186.00 sep 1.8 mag 6.70,8.52 Sp A1V dist. 165.29 pc (539.18 l.y.)
BU 411 AB: 152; 200x: Faint, very close split. 15% PRO, a poor PMV, only 59 AU WS, 1.4+1.1 Msol, it is probably binary. SOC grade 2 orbit, 159.3-year period, it is at apastron and won't have much change the next coupld of decades.
10h 36m 04.49s -26° 40' 31.6" P.A. 303.00 sep 1.3 mag 6.68,7.77 Sp F6V dist. 41.25 pc (134.56 l.y.)
HJ 4311 AB: 152; 125x: Very bright primary and well split faint secondary, looks like a star with a planet. 36% PRO, 249 AU WS, poor PMV, 1.6+0.7 Msol, it is possibly binary and needs an orbit
10h 23m 17.55s -13° 22' 37.7" P.A. 119.00 sep 4.7 mag 6.70,10.26 Sp F5V dist. 53.45 pc (174.35 l.y.)
HU 1128 AB: 152; 125x: Wide B noticed with averted vision then can hold. 75% PRO, 68 AU WS, negative PMV, and RVD 4.8 < EV 5.6. SOC grade 5 orbit 241-year period.

LDS2863 AB: 152; 125x: 4 Dm, super wide, white A, light orange B. These appear to share a similar proper motion, but there is only 1% PRO, 1,588 AU WS, 1.2+0.5 Msol, but RVD 2.8 > EV 1.4, it is not binary.
10h 30m 37.58s +55° 58' 49.9" P.A. 303.00 sep 122.8 mag 4.88,8.86 Sp F8V+K7V dist. 12.78 pc (41.69 l.y.)
STF1405 AB: 152; 125x: White stars, well separated, B detected with averted vision then can hold. 18% PRO, 2,800 AU WS, 2.0+0.8 Msol, but RVD 3.6 > EV 1.3, it is not binary.
10h 05m 55.92s +39° 34' 55.7" P.A. 252.00 sep 22.2 mag 7.30,11.76 Sp A9V dist. 105.82 pc (345.18 l.y.)
STF1424 AB: 152; 125x: Algieba. Lovely same color light-yellow stars, 3 Dm, well split. Seen with the 60mm too, with 40x and best at 90x, with nice diffraction rings. No Gaia data. SOC grade 4 orbit, 554-year period.
10h 19m 58.35s +19° 50' 29.4" P.A. 127.00 sep 4.7 mag 2.37,3.64 Sp K1III+gG7 dist. 39.89 pc (130.12 l.y.)
STF1426 AB: 152; 250x: Unequal hairline with seeing only. No Gaia data for A. SOC grade 4 orbit, 774-year period.
10h 20m 32.32s +06° 25' 47.6" P.A. 315.00 sep 0.9 mag 7.99,8.30 Sp F5 dist. 149.7 pc (488.32 l.y.)
STF1431 AB: 152; 125x: 2 Dm, nicely split. -1% PRO, poor PMV, it is not likely binary.
10h 25m 35.12s +08° 46' 35.4" P.A. 76.00 sep 3.6 mag 7.76,9.07 Sp A8III dist. 151.98 pc (495.76 l.y.)
STF1432 AB: 152; 125x: Super wide, 2 Dm. -93% PRO, it is not binary.
10h 26m 59.53s +29° 40' 31.0" P.A. 121.00 sep 28.6 mag 7.84,10.28 Sp F2 dist. 100.3 pc (327.18 l.y.)
STF1440 AB: 152; 125x: 1 Dm, wide. Only 6% PRO, a poor PMV, it is not likely binary.
10h 29m 49.23s -03° 54' 55.2" P.A. 345.00 sep 14.8 mag 7.81,9.17 Sp G0 dist. 145.35 pc (474.13 l.y.)
STF1441 AB: 152; 200x: Excellent pair, light orange stars with a closely split 2 Dm B. No Gaia data for B. Low chance of it being binary, given the distance from us and the relatively wide split. An orbit can be tried all the same.
10h 30m 58.78s -07° 38' 15.2" P.A. 167.00 sep 2.8 mag 6.51,8.81 Sp K5III+F6V dist. 348.43 pc (1136.58 l.y.)
STF1450 AB: 152; 200x: Very fine close split, dull white stars, 2 Dm. No Gaia data for B. Given the distance from us, I don't think chances are good for it to be binary.
10h 35m 02.16s +08° 39' 01.6" P.A. 157.00 sep 2.0 mag 5.80,7.90 Sp A2V dist. 131.41 pc (428.66 l.y.)
STF1457 AB: 152; 200x: Very closely split unequal pair. -62% PRO, it is not binary.

STFB 6 AB: 60; 40x: Unequal super wide. No Gaia data.
10h 08m 22.31s +11° 58' 01.9" P.A. 304.00 sep 179.2 mag 1.40,8.24 Sp B7V dist. 24.31 pc (79.3 l.y.)
STT 215 AB: 152; 250x: Very fine white unequal pair, close clean split with high power, suspected lower powers. 31% PRO, 152 AU WS, 1.9+1.8, it is probably binary. SOC grade 4 orbit, 468-year period.
10h 16m 16.05s +17° 44' 24.6" P.A. 176.00 sep 1.5 mag 7.25,7.46 Sp A9IV dist. 114.55 pc (373.66 l.y.)
STT 216 AB: 152; 250x: Difficult, with seeing, two hazy hairline split stars. Elongates with averted vision. -32% PRO, 1.0+0.6 Msol, RVD 2.0 < EV 6.8. There is a SOC grade 3 orbit, 315-year period, it may well be binary in spite of the parallax discrepancy.
10h 22m 43.81s +15° 20' 39.7" P.A. 228.00 sep 2.5 mag 7.38,10.28 Sp G5 dist. 28.77 pc (93.85 l.y.)
STT 219 AB: 152; 125x: B seen with averted vision only. -73% PRO, it is not binary.
10h 30m 11.49s +50° 59' 36.2" P.A. 297.00 sep 13.2 mag 7.60,11.70 Sp A7IV dist. 158.48 pc (516.96 l.y.)
STT 523 AB: 152; 200x: Very faint B seen with averted vision only, well split. 71% PRO, 173 AU WS, 1.2+0.4 Msol, RVD 4.2 > EV 4.0, but not by much. It is possibly binary and an orbit is needed.
10h 17m 14.53s +23° 06' 22.3" P.A. 300.00 sep 7.9 mag 5.80,11.30 Sp F6V+M1.5 dist. 22.81 pc (74.41 l.y.)
