two nights this week

I'm combining the observations from two nights earlier this week, only to save some time.  Both nights the seeing was forecasted to be good, and it was pretty decent but only enough to mask to 7-inches.  The first night I focussed on Struves in Lynx (of which there are quite a lot).  The second night, finding I had already observed most the of higher declination Struves, went after a few low in Canis Major, adding some Burnhams which were all in the same area (and visible to me through a slot in the neighbor's bushes).  Pretty good overall.

STF 946 AB: 178; 150x: Light yelow A and 2 Dm, more deeply yellow B, fairly closely separated around 4".  WDS uncertain, however there is no parallax range overlap, -85%, so they are not binary.
06h 44m 51.62s +59° 26' 57.4" P.A. 129.00 sep 4.0 mag 7.30,9.11 Sp F5 dist. 101.11 pc (329.82 l.y.)

STF 881 AB; 178; 600x: 4 Lyn. Very difficult, barest of separations with seeing only, 2 Dm.  WDS binary with 503-year period, it will not make any appreciable change in the coming years.  No Gaia data.
06h 22m 03.57s +59° 22' 19.5" P.A. 150.90 sep 0.6 mag 6.13,7.71 Sp A3V dist. 152.21 pc (496.51 l.y.)

STF 887 AB: 178; 150x: Extremely faint pair, wide, 2 Dm.  WDS not physical, and there is no parallax range overlap, -97%.

STF 916 AB: 178; 150x: White stars, B is considerably fainter, wide.  WDS uncertain, and there is -14% parallax range overlap, so it is not binary.
06h 34m 12.46s +56° 38' 46.1" P.A. 254.00 sep 9.4 mag 9.43,10.55 Sp A3

STF 923 AB: 178; 150x: Light yellow-orange A, wide 2 Dm B.  WDS says parallax indicates physical, however I don't know what they're smoking, there is -94% parallax range overlap, it is not binary.
06h 38m 06.95s +59° 26' 57.9" P.A. 144.00 sep 33.0 mag 7.57,11.47 Sp G8III dist. 226.24 pc (737.99 l.y.)

STF 936 AB: 178; 300x: Light orange A and blue B, delicate split at 200x, better at 300x, 2 Dm, 1" separation, very pretty.  WDS uncertain, and there is no Gaia data for the B component.
06h 39m 43.55s +58° 05' 42.1" P.A. 284.00 sep 1.1 mag 7.26,9.04 Sp G5 dist. 254.45 pc (830.02 l.y.)

STF 963 AB-C: 178; 150x: Light yellow-orange A and very faint B, well separated, not physical.  A is not round at 300-600x but it will not resolve with 7-inch aperture, and seeing would not support 20-inch aperture. 
06h 53m 05.06s +59° 26' 55.2" P.A. 359.30 sep 0.3 mag 6.00,6.53 Sp G4III+A2V dist. 149.25 pc (486.85 l.y.)

STF 968 AB: 178; 150x: Straight-forward Struve, white stars, wide, 1 Dm.  WDS uncertain, but there is 50% parallax range overlap, a pretty wide 5,245 AU weighted separation, 2.3+1.8 Msol, so there is a chance it is binary.

06h 52m 52.01s +52° 40' 49.5" P.A. 289.00 sep 20.7 mag 8.28,9.19 Sp A3

STF1020 AB: 178; 150x: White A and 2 Dm B, wide, seen with direct vision but brightens considerably with averted vision.  WDS says parallax indicates physical, but they are wrong again, -52% parallax range overlap, they are not binary.
07h 11m 56.72s +57° 30' 27.5" P.A. 285.00 sep 13.3 mag 8.76,10.44 Sp F5

STF1032 AB: 178; 300x: Challenging, white A, 3 Dm and very closely separated B, seen only with foveal coaxing.  WDS uncertain, but there is -2 parallax range overlap, so not likely binary.
07h 13m 52.61s +48° 29' 55.8" P.A. 114.00 sep 2.7 mag 7.32,10.34 Sp A2V dist. 148.81 pc (485.42 l.y.)

STF1033 AB: 178; 200x: Very finely split at 150x, better seen at 200x, white A and very light blue B, 1 Dm, very pretty.  WDS uncertain, but there is 33% parallax range overlap, only 280 AU weighted separation, 2.2+1.9 Msol, so there's a good chance it's binary.
07h 14m 48.05s +52° 32' 44.1" P.A. 278.00 sep 1.5 mag 7.81,8.44 Sp F0 dist. 271 pc (884 l.y.)

STF1040 AB: 178; 150x: Blue-white A and red B, wide, 2 Dm.  WDS says physical, and there is 7% parallax range, 1,321 AU weighted separation, 1.7+1.2 Msol, so there is some chance it is binary.
07h 16m 20.14s +48° 12' 54.0" P.A. 261.00 sep 7.3 mag 8.79,10.34 Sp A3

STF1044 AB: 178; 150x: White A and slightly fainter wide B.  WDS says not physical, however they prove themselves incorrect again: 69% parallax range overlap, 1,106 AU weighted separation, 0.9+0.9 Msol -- so there is some chance this could be binary.
07h 17m 08.96s +47° 39' 18.1" P.A. 169.00 sep 13.1 mag 10.08,10.60 Sp K0

STF1065 AB: 178; 150x: Equal white stars, very wide.  WDS says proper motion indicates physical, but there is -7% parallax range overlap, so they cannot be binary. 
07h 22m 15.11s +50° 08' 55.7" P.A. 256.00 sep 15.1 mag 7.51,7.67 Sp A6II dist. 283.29 pc (924.09 l.y.)

STF1092 AB: 178; 150x: Very nice close split around 3", almost 2 Dm.  WDS uncertain, but there is -4% parallax range overlap, so it is not binary.

STF1093 AB: 178; 300x: Excellent pair, near equal, elongated at 150x, delicate split at 200x, best seen at 300x.  WDS gives and orbital solution with a 715-year period, and there is 28% parallax range overlap, only 115 AU weighted separation, 1.5+1.4 Msol.  

07h 30m 16.51s +49° 58' 42.0" P.A. 207.40 sep 0.9 mag 8.79,8.98 Sp F5 dist. 90.42 pc (294.95 l.y.)

STF1117 AB: 178; 150x: Wide one delta, faint stars.  WDS says parallax indicates physical, but in reality there is no parallax range overlap, -60%, so it is not binary.

07h 36m 43.19s +35° 23' 30.0" P.A. 228.00 sep 11.6 mag 9.10,10.59 Sp F0

STF1145 AB: 178; 300x: Fine pair, a challenge with 3 Dm, very closely split at 200x, best seen with 300x.  WDS uncertain, but there is -54% parallax range overlap, it is not binary.

STF1204 AB: 178; 150x: Easy, wide, 1 Dm.  WDS says physical, but there is -46% parallax range overlap, it is not binary.
08h 15m 54.24s +38° 28' 53.3" P.A. 104.00 sep 11.5 mag 9.24,10.33 Sp F8

STF1211 AB: 508; 800x: AC is a wide 1 Dm pair.  The A star is suspected of being out of round with 7-inch 300x, one detla, with PA to the south.  It resolves to a near equal pair, hairline split, with 20-inch at 800x.  AB has an orbital solution in WDS, 407-year period, it will widen to 0.6" by the 2040s.
08h 18m 19.65s +38° 59' 10.0" P.A. 156.60 sep 0.4 mag 9.65,9.97 Sp K0 dist. 62.97 pc (205.41 l.y.)

STF1222 AB: 178; 150x: Easy, 1 Dm, wide.  WDS says parallax indicates physical, and there is 82% overlap of the parallax ranges, 2,179 AU weighted separation, 1.9+1.4 Msol, so it is very possibly binary.

08h 26m 20.39s +37° 32' 43.3" P.A. 49.00 sep 10.0 mag 8.71,10.20 Sp A3 dist. 502.51 pc (1639.19 l.y.)

STF1239 AB: 178; 150x: Rather uninteresting, wide separation, >1 Dm.  WDS says parallax indicates physical, however there is -22% (no) overalp of the parallax ranges, so it cannot be binary.
08h 32m 29.47s +37° 29' 19.8" P.A. 290.00 sep 12.8 mag 9.64,11.03 Sp A5

STF1282 AB:178; 150x: Lovely white stars, near equal, around 3" separation, pleasingly close at this low mangnification.  WDS orbital solution with 804-year period.  There is 29% overlap of the parallax ranges, only 195 AU weighted separation, 1.3+1.3 Msol, and the radial velocity delta 0.7 is less than the escape velocity 4.8, so it is binary.  Too bad the human lifespan is so short as it will tighten to an impossibly close separation 300 years from now.
08h 50m 44.28s +35° 04' 15.4" P.A. 278.70 sep 3.4 mag 7.59,7.76 Sp F8 dist. 51.6 pc (168.32 l.y.)

STF1296 AB: 178; 150x: Beautiful hair, hairline split with low magnification, 0.5 Dm.  WDS says parallax indicates physical, and there is 54% overlap of their parallax ranges, only 184 AU weighted separation, 1.2+1.0 Msol, and the radial velocity delta 0.3 is less than the escape velocity 4.7, so it is very likely binary.

08h 59m 16.74s +34° 56' 46.9" P.A. 76.00 sep 1.9 mag 9.05,9.95 Sp G5

STF1274 AB: 178; 150x: White A and light orange B, wide, 2 Dm.  WDS uncertain, but there is 90% overlap of their parallax ranges, 2,014 AU weighted separation, 2.6+1.7 Msol, so it is quite likely binary. 
08h 49m 00.34s +38° 20' 42.9" P.A. 42.00 sep 9.1 mag 7.42,9.34 Sp A2 dist. 241.55 pc (787.94 l.y.)

STF1279 AB: 178; 200x: Lovely white stars, finely split, slightly unequal.  WDS uncertain, but there is -67% parallax range overlap, so it is not binary.
08h 49m 59.98s +39° 35' 23.3" P.A. 88.00 sep 1.1 mag 9.16,9.25 Sp G0 dist. 133.16 pc (434.37 l.y.)

STF1259 AB: 178; 150x: Very faint but easy pair, 1 Dm, widely split around 5".  WDS says proper motion indicates physical, and there is 74% parallax range overlap, 1,009 AU weighted separation, 1.6+1.4 Msol, and the radial velocity delta 0.6 is less than the escape velocity 2.3, so it is binary.
08h 46m 35.58s +38° 29' 08.6" P.A. 341.00 sep 5.2 mag 9.45,9.95 Sp G0 dist. 144.3 pc (470.71 l.y.)

STF1251 AB: 178; 150x: Faint stars, 1 Dm, fairly wide.  WDS says parallax indicates physical, but there is -64% parallax range overlap, so they are not binary.

STF1244 AB: 178; 150x: 2 Dm, fairly wide around 4".  WDS says physical, but there is exactly 0% parallax range overlap, 597 AU weighted separation, 1.6+1.1 Msol -- it could be binary, but certainly more time is needed to trace their paths.
08h 37m 39.24s +41° 48' 02.3" P.A. 1.00 sep 3.7 mag 9.02,10.32 Sp G8III dist. 157.23 pc (512.88 l.y.)

STF1160 AB: 178; 150x: White stars, 2 Dm, well split.  WDS says not physical, and there is -7% parallax range overlap, so likely not binary.

STF1165 AB: 508; 667x: AB-C is a super-wide, faint pairing, almost 4 Dm.  Close pair AB (which is the same as STF 1166) observed an elongation with the weaker end to the west.  It was discovered at 0.7" so it has closed considerably.  WDS uncertain, and unfortunately no Gaia data for the B star.
08h 02m 07.40s +54° 36' 54.8" P.A. 318.00 sep 0.2 mag 8.60,10.03 Sp A0 dist. 232.02 pc (756.85 l.y.)

STF1200 AB: 178; 150x: Easy white stars, near equal, wide.  WDS uncertain, there is 19% parallax range overlap, 1,816 AU weighted separation, and 1.8+1.8 Msol, so there's a fair chance it is binary.
08h 15m 58.26s +49° 46' 19.5" P.A. 181.00 sep 8.3 mag 9.16,9.33 Sp G0 dist. 165.84 pc (540.97 l.y.)

STF1205 AB: 178; 200x: Very delicate split at 150x, better at 200x, near equal faint stars. WDS uncertain, but there is -62% parallax range overlap, it is not binary.

BU 209 AB: 178; 150x: Excellent pair, nice close split around 1", nearly 1 Dm.  WDS uncertain, but there is 35% parallax range overlap, only 162 AU weighted separation, 1.5+1.4 Msol, so it is most likely binary.  Burnham discovered with 6-inch at 2.0", it has closed considerably since.
08h 43m 13.12s +38° 48' 31.9" P.A. 9.00 sep 1.2 mag 8.72,9.01 Sp F5 dist. 145.99 pc (476.22 l.y.)

BU 576 AB: 178; 300x: Very momentary resolution of a exceptionally fiant B in A' diffraction, more than 1" separation.  WDS says physical, but there is (surprisingly) no parallax range overlap, -75%, so it is not binary.  Burnham discovered with the 18.5-inch refractor.

STF1011 AB: 178; 150x: Pretty faint, 1 Dm, light orange stars, about 4" separation.  WDS uncertain, but there is 31% parallax range overlap, 968 AU weighted separation, 2.0+1.8 Msol, so it is possible to be binary.
07h 00m 50.91s -15° 18' 56.8" P.A. 300.00 sep 4.2 mag 8.52,9.00 Sp A2/3V

STF1031 AB: 178; 150x: Faint pair, near equal, white, around 4" separation.  WDS says parallax indicates physical, but there is -14% parallax range overlap, so they are not binary.

BU 332 AB: 178; 300x: Light yellow stars, appears as a snowman / overlapping discs, PA to the south.  WDS uncertain, and there is no Gaia data for the secondary.   0.8" at discovery, component of STF1097 AC which is a nearly 3 Dm pair very widely separated PA to the northwest.

BU 574 AB: 178; 300x: Very excessively faint B star barely detected, PA northwest.  WDS says not physical, however there is 72% parallax range overlap, 2,548 AU weighted separation, 5.5+2.5 Msol, so it very much may be binary.  Burnham discovered with the 18.5-inch Dearborn refractor.
07h 06m 56.44s -11° 19' 38.5" P.A. 308.00 sep 2.4 mag 7.66,11.05 Sp B0.5V dist. 694.44 pc (2265.26 l.y.)

BU 575 AB: 178; 300x: Orange A appears as overlapping near equal discs with high power.  WDS orbital solution with a 402-year period, no Gaia data for the B star.  STF 1057 AB-C is a blue star, very wide, 2 Dm.

BU 198 AB: 178; 150x: Light orange stars, 3 Dm, well split, seen with averted vision at first then can hold direct.  WDS says not physical, and there is no overlap of parallax ranges, -42%.  Burnham discovered with 6-inch and said "The larger star is red."

BU 199 AB: 178; 300x: >1 Dm, closely split about 3".  WDS says not physical, but there is 93% parallax range overlap, 4,360 AU weighted separation, 9.4+7.6 Msol, so it is very possible to be binary!  DAM1372 AD is a wide near equal PA to the east, of which WDS is uncertain, but this is a comoving pair, not binary: 59% parallax range overlap but a tremendous 253,363 AU weighted separation, 9.4+7.4 Msol, but too far apart to hold a barycenter. 
07h 25m 07.97s -21° 10' 25.9" P.A. 24.00 sep 1.8 mag 7.21,8.05 Sp B1Iab dist. 14285.71 pc (46599.99 l.y.)

BU 331 AB: 178; 200x: 1 Dm, with beast moments of seeing only, close split around 2".  WDS uncertain, however there is 36% parallax range overlap, 834 AU weighted separation, 2.9+2.4 Msol, so it is likely binary.  Burnham discovered with 6-inch at 2.0, unchanged since. 
07h 20m 02.73s -24° 24' 57.7" P.A. 117.00 sep 2.0 mag 8.30,9.11 Sp ApSi dist. 293.26 pc (956.61 l.y.)

BU 572 AB: 178; 200x: Very excessively faint B around 3" separation.  WDS says not physical, and there is -48% parallax range overlap.  Burnham discovered with the 18.5-inch and says "Many small stars in the field"  J2000 coordinates put this in open star cluster Tombaugh 1 -- Burnham first to notice it as a cluster, but maybe didn't use low enough magnification to detatch the cluster from its surroundings.  
07h 00m 35.09s -20° 38' 25.1" P.A. 142.00 sep 5.2 mag 6.76,10.02 Sp A4m+A5/A9 dist. 240.96 pc (786.01 l.y.)

BU 578 AB: 178; 200x: NR CMa.  Very difficult, the barest fleck of a star just separated, fleeting, at best moments only.  WDS says not physical, however there is 4% parallax range overlap, only 127 AU weighted separation, 2.5+1.1 Msol, so it might be binary (though the proper motion vector is negative, meaning they're moving in opposite directions, though this might just be due to the direction of the orbit?)

07h 27m 07.99s -17° 51' 53.4" P.A. 39.00 sep 1.3 mag 5.66,9.23 Sp A5n dist. 92.34 pc (301.21 l.y.)

11 march 2022 physical pairs

Seeing was forecast to be pretty good, excellent after midnight.  So I observed with the 20-inch starting around 9:30pm.  It was good enough to push the limits somewhat, and in doing so I took more time for each observation so there is a shorter list to report.  Seeing seemed to break down a bit at midnight (I could feel the air become much colder suddenly), so I decided not to go further.  Ended with some terrific views of the waxing moon which was still high enough in the sky.

Continued my march through Struve pairs, this time mainly Cancer and Hydra.  I finished with a string of BUs in Hydra.  Overall the BUs are consistently more challenging, and therefore more exciting, than the STFs, so I'll always make room for them.  Seeing with the 7-inch was very good, 8/10, but it didn't quite support 20-inches.  There was a marine haze and dew throughout, a little cold.  Observed from 9-11pm.

A very productive night flying through Struves in Auriga, which has taken me several days to put togehter in a post as there were so many observations.  Seeing was good enough for 7-inches but did not hold up well with 20-inches, so it was a fine night for these pairs.  Many similar wide and moderate delta magnitude pairs, plus a few pleasant surprises along the way.  Observed from around 8:30-10:30pm

STF 684 AB: 178; 205x: Resolved with seeing, nearly 2 Dm, white A and blue B, very closely split around 2".  WDS uncertain, but there is no overlap of the parallax ranges, -11%, so they are not binary, which is too bad because this is a pretty pairing.
