Had a relatively short session, since it's summer, from around 9:45pm to 11:15pm, but still plenty of pairs observed with the 6-inch. I'm pretty efficient now with the Nexus to bring up targets in order of RA and using the laptop with ST just to type in the observation. Very good transparency, good seeing (airy disks at 200x).
STF1662 AB: 152; 125x: Pretty light orange A, 2 Dm deeper orange B, wide. WDS says not physical, and there is no -38% overlap of the parallax ranges, it is not binary.
12h 35m 48.64s +56° 34' 42.4" P.A. 243.00 sep 19.3 mag 7.83,9.75 Sp K0III dist. 167.22 pc (545.47 l.y.)
STF1691 AB: 152;125x: White and nearly 2 Dm B, very wide. WDS says proper motion indicates physical, and there is 99% overlap of the parallax ranges, 2,660 AU weighted separation, 1.6+1.2 Msol, and the radial velocity delta 1.1 is less than the escape velocity 1.4, so it is likely binary.
12h 54m 59.60s +58° 09' 37.6" P.A. 276.00 sep 18.7 mag 8.58,9.80 Sp F0IV dist. 68.17 pc (222.37 l.y.)
STF1695 AB: 152; 150x: White A and light-yellow B, nearly 2 Dm, closely separated. Split at 125x but higher power showed nice airy disks and a clearer image. WDS says it's physical, and there is 77% overlap of the parallax ranges, only 324 AU weighted separation, 2.2+1.5 Msol, so it is likely binary.
12h 56m 17.64s +54° 05' 58.1" P.A. 280.00 sep 3.7 mag 6.04,7.75 Sp A5m dist. 86.66 pc (282.68 l.y.)
STF1732 AB: 152; 125x: Faint pair, very wide, about 1 Dm. WDS says physical, but notes "parallax indicates physical, Proper motion indicates non-physical." There is 2% parallax range overlap, 1,936 AU weighted separation, 1.2+0.5 Msol, but the radial velocity delta 3.3 exceeds the escape velocity 1.2, and this explains why it is not binary.
13h 12m 37.57s +58° 26' 56.6" P.A. 127.00 sep 25.9 mag 8.68,10.42 Sp F7V dist. 82.51 pc (269.15 l.y.)
STF1752 AB: 152; 250x: Difficult, with seeing and high power, 1 Dm but seems fainter due to its closeness to A, around 1" separation. WDS grade 5 orbit, 500-year period. Unfortunately, Gaia shows there is no overlap of the parallax ranges, -26%, and in spite of the 73 AU weighted separation and 8.0+1.3 Msol, it is not likely binary.
13h 28m 49.82s +59° 55' 41.7" P.A. 103.60 sep 0.9 mag 8.19,9.90 Sp F8 dist. 73.42 pc (239.5 l.y.)
STF1754 AB: 152; 125x: Faint, very wide B on the edge of detectably, it appears as a fine point, brightens with averted vision. WDS says not physical, and there is no -92% overlap of the parallax ranges, it is not binary.
13h 29m 58.81s +60° 21' 12.5" P.A. 14.00 sep 24.3 mag 8.18,10.61 Sp G5 dist. 387.6 pc (1264.35 l.y.)
STF1770 AB: 152; 175x: Beautiful close pair, light orange stars, 2 Dm. Split with lower magnifications but best seen 175x. WDS says it is physical, but there is no -60% parallax range overlap, it is not binary.
13h 37m 42.92s +50° 42' 53.5" P.A. 123.00 sep 1.7 mag 6.93,8.18 Sp K3III: dist. 434.78 pc (1418.25 l.y.)
STF1774 AB: 152, 125x: Light yellow-white A and 2 Dm wide B. WDS uncertain, but there is no -30% overlap of the parallax ranges, it is not binary.
13h 40m 23.35s +50° 31' 09.4" P.A. 135.00 sep 17.3 mag 6.34,10.51 Sp F7.7V dist. 25.33 pc (82.63 l.y.)
STF1784 AB: 152: 125x: White A and much fainter B, >2Dm, well split. WDS says it's physical, but there is no overlap (-86%) of the parallax ranges, it is not binary.
13h 44m 25.25s +69° 13' 11.8" P.A. 204.00 sep 9.1 mag 8.12,10.82 Sp F5 dist. 124.53 pc (406.22 l.y.)
STF1795 AB: 152; 125x: White A and 3 Dm well separated B. WDS uncertain, but there is 21% parallax range overlap, 1,288 AU weighted separation, 2.5+1.2 Msol, so it is likely binary.
13h 58m 55.41s +53° 06' 23.2" P.A. 2.00 sep 8.0 mag 6.91,9.83 Sp A3IV-V dist. 156.49 pc (510.47 l.y.)
STF1820 AB: 152; 125x: Excellent close pair, <1 Dm, very light orange stars. WDS showing two orbital solutions, but both are impossibly close and cannot refer to AB. There is no overlap of the parallax ranges, -92%, so it is not binary.
14h 13m 00.76s +55° 19' 31.1" P.A. 123.00 sep 2.8 mag 9.06,9.42 Sp K2 dist. 38.26 pc (124.8 l.y.)
STF1827 AB: 152; 125x: Faint pair, near equal, wide, white. WDS says parallax indicates physical, and there is 68% overlap of the parallax ranges, 2,294 AU weighted separation, 1.6+1.5 Msol, and the radial velocity delta 0.3 is less than the escape velocity 1.5, so it is very likely binary.
14h 14m 11.87s +59° 14' 34.2" P.A. 209.00 sep 11.3 mag 9.62,9.91 Sp G5
STF1845 AB: 152: 125x: Wide and very much fainter B, seen with averted vision and can then hold it direct. WDS says it is not physical, and there is -99% parallax range overlap, it is not binary.
14h 23m 43.36s +61° 56' 13.5" P.A. 311.00 sep 44.1 mag 8.34,12.04 Sp F8 dist. 77.88 pc (254.04 l.y.)
STF1892 AB: 152; 125x: Faint pair, very closely split, near equal. WDS uncertain, and there is 2% parallax range overlap, only 399 AU weighted separation, 1.2+1.1 Msol, and the radial velocity delta 0.6 is less than the escape velocity 3.2, so it is likely binary.
14h 52m 37.33s +59° 03' 03.8" P.A. 236.00 sep 3.1 mag 9.68,10.48 Sp G5
STF1898 AB 152; 175x: Very beautiful close pair, nearly 2Dm, best seen with moderate power. WDS uncertain, but there is 34% overlap of the parallax ranges, only 306 AU weighted separation, 1.5+1.0 Msol, so it is possibly binary.
14h 56m 29.60s +59° 22' 47.6" P.A. 217.00 sep 2.9 mag 8.26,10.32 Sp F8 dist. 102.04 pc (332.85 l.y.)
STF1918 AB: 152; 125x: PX Dra, the primary has a range of 6.82-6.95 V. Bright white A and faint wide B, about 3 Dm. WDS says not physical, and there is -37% parallax range overlap, it is not binary.
15h 07m 50.16s +63° 07' 01.6" P.A. 20.00 sep 17.8 mag 6.89,10.29 Sp F5IV-V dist. 95.42 pc (311.26 l.y.)
STF1927 AB: 152; 125x: White stars, near equal, wide. BV Dra, 7.88 - 8.48 V over 8.4 hours! WDS says parallax indicates physical, and there is 19% overlap of the parallax ranges, 988 AU weighted separation, 1.2+1.0 Msol, so it is likely binary.
15h 11m 50.36s +61° 51' 25.3" P.A. 354.00 sep 16.0 mag 8.12,8.81 Sp F9V+B0 dist. 70.52 pc (230.04 l.y.)
STF1948 AB: 152; 125x: Ice-blue A and orangish B, 1 Dm, well separated. WDS says proper motion indicates physical, but there is -55% overlap of the parallax ranges, it is not binary.
15h 26m 34.86s +54° 53' 56.5" P.A. 48.00 sep 12.9 mag 8.71,9.65 Sp A5 dist. 127.71 pc (416.59 l.y.)
STF1975 AB: 152; 125x: Very faint B seen with averted vision only, white A, wide. WDS says it is not physical, and there is -87% parallax range overlap, it is not binary.
15h 42m 41.93s +67° 03' 59.8" P.A. 43.00 sep 18.9 mag 8.09,11.80 Sp K5 dist. 1030.93 pc (3362.89 l.y.)
STF1976 AB: 152; 125x: Faint pair, near equal, wide. WDS says proper motion indicates physical. There is just 1% of parallax range overlap, 6,163 AU weighted separation, 1.9+1.8 msol, and the radial velocity delta 0.2 is less than the escape velocity 1.0. This might be binary, but the near lack of parallax overlap is not in its favor.
15h 44m 54.96s +59° 25' 42.9" P.A. 72.00 sep 19.3 mag 9.66,9.92 Sp A8V
STF1996 AB: 152; 125x: Faint pair, wide, <1 Dm. WDS says parallax indicates physical, and there is 96% overlap of the parallax ranges, 4,362 AU weighted separation, 1.4+1.3 Msol, and the radial velocity delta 0.4 is less than the escape velocity 1.0, so this is likely binary, though the weighted separation is a bit far.
15h 56m 31.13s +57° 16' 57.7" P.A. 108.00 sep 19.4 mag 10.22,10.65 Sp F8+K
STF2006 AC 152; 125x: Wide pair one delta. Did not see AB 8.48/9.96 1.5". AC has no parallax range overlap, -95%, so it is not binary. Nor does AB, -79%.
16h 00m 18.28s +58° 56' 03.0" P.A. 211.00 sep 48.0 mag 8.48,9.74 Sp A3 dist. 206.19 pc (672.59 l.y.)
STF2009 AB: 152; 125x: 1 Dm, wide stars. WDS says parallax indicates physical, but the parallax ranges do not overlap, -1%. 2,971 AU weighted separation, 1.5+1.1 Msol, and the radial velocity delta equals the escape velocity, 1.2. Some question whether this is binary, as opposed to co-moving.
16h 01m 59.06s +60° 28' 57.3" P.A. 301.00 sep 17.0 mag 9.42,10.71 Sp F8
STF2045 AB: 152; 125x: Exceptionally fine close pair, >1 Dm, cream-white A and blue B. WDS says this is not physical, but there is 31% parallax range overlap, only 302 AU weighted separation, 1.5+1.1 Msol, so it is possible it is binary.
16h 20m 18.35s +61° 29' 46.0" P.A. 186.00 sep 2.2 mag 8.80,10.18 Sp F8
STF2046 AB: 152; 125x: Faint pair, 1 Dm, well split. WDS says this is physical, but there is no overlap of the parallax ranges, -34%, it is not binary.
16h 20m 53.83s +64° 21' 45.7" P.A. 221.00 sep 8.0 mag 9.73,10.30 Sp F8
STF2060 AB: 152; 125x: Faint near equal pair, closely split. WDS says this is not physical, but there is 85% parallax range overlap, 1,131 AU weighted separation, 1.7+1.6 Msol, so it very likely is binary.
16h 28m 32.06s +56° 44' 07.9" P.A. 247.00 sep 3.8 mag 10.19,10.26 Sp G5 dist. 307.69 pc (1003.68 l.y.)
STF2092 AB: 152; 125x: Pretty white and 2 Dm, well split B. WDS says proper motion indicates physical, and there is 6% parallax range overlap, 1,271 AU weighted separation, 1.7+1.3 Msol, so it is possible to be binary.
16h 39m 03.98s +60° 41' 58.8" P.A. 5.00 sep 8.2 mag 8.69,9.64 Sp G1IV dist. 118.34 pc (386.03 l.y.)
STF2099 AB: 152; 125x: Quite faint B seen with averted vision at first then can just hold direct, well separated from white A. WDS says this is physical, but there is no -53% parallax overlap, it is not binary.
16h 38m 21.31s +70° 20' 18.4" P.A. 216.00 sep 9.8 mag 9.45,10.90 Sp K0
STF2108 AB: 152; 125x: 2 Dm wide pair. WDS says proper motion indicates it is physical. There is 87% parallax range overlap, 1,757 AU weighted separation, 1.0+0.7 Msol, but the radial velocity delta 1.7 is more than the escape velocity 1.3 -- is it probable this is a co-moving pair.
16h 48m 36.08s +55° 07' 45.7" P.A. 350.00 sep 26.6 mag 8.97,11.24 Sp G5 dist. 64.31 pc (209.78 l.y.)
STF2116 AB: 152; 125x: Wide, white, near equal. WDS uncertain, but there is 11% parallax range overlap, 4,080 AU weighted separation, a little far, 1.7+1.4 Msol, so it is somewhat possible this is binary.
16h 55m 13.49s +63° 31' 41.6" P.A. 4.00 sep 19.1 mag 9.40,10.12 Sp G5 dist. 81.43 pc (265.62 l.y.)
STF3084 AB: 152; 125x: White A and wide faint B, needed foveal coaxing to hold B. WDS says it's physical, but there is no, -78%, parallax range overlap, it is not binary.
