hercules doubles

Last night's seeing was quite good, with moments of perfection. I'm convinced now the sealed back with fan blowing out, rather than a boundary layer fan blowing across, is the best solution. Really nice night. Since it was a Friday night I stayed out a little longer than usual, until I was too tired to go on. Nice to observe again especially after a very trying week at work after returning from the eclipse. With Big Blue from the back yard, 553x throughout. Skytools scrambled the order...

STF 2061. Nice yellowish with 3 delta mag. B, ~2"
16H 33M 12.49S +30° 54' 27.0" P.A. 30 SEP 2.3 MAG 7.92,10.44 SP F2 DIST. 121.21 PC (395.39 L.Y.)

STF 2084: Can't see B. Should have been visible; I went to 277x mag to clean up bright star magnification but did not help, seeing seems to be deteriorating.
16H 41M 17.16S +31° 36' 09.8" P.A. 124.1 SEP 1.28 MAG 2.95,5.40 SP G1IV DIST. 10.72 PC (34.97 L.Y.)

STF 2097: Pair split in finder but one is a near equal close pair ~2-3" [AB seen, there are 4 stars in system]
16H 44M 47.22S +35° 44' 16.7" P.A. 80 SEP 1.8 MAG 9.37,9.55 SP G5 DIST. 125 PC (407.75 L.Y.)

STF 2101: Blue-white and slightly red B, 2 delta mag, wide. [AB seen there are 4 pairs in the system]
16H 45M 48.14S +35° 37' 50.5" P.A. 47 SEP 4.1 MAG 7.51,9.39 SP F6V DIST. 58.82 PC (191.87 L.Y.)

STT 324: Orange with 2 fainter 2 delta mag bluish stars making an equilateral triangle. [Missed this one, it had a close fainter B, should have been visible]
17H 08M 00.70S +31° 12' 22.5" P.A. 219 SEP 3.6 MAG 6.00,10.70 SP K3III DIST. 458.72 PC (1496.34 L.Y.)

STF 2104: 2 delta mag, wide.
16H 48M 41.48S +35° 55' 19.3" P.A. 17 SEP 5.7 MAG 7.49,8.78 SP F2 DIST. 172.71 PC (563.38 L.Y.)

KUI 72: Distinct faint point appears with perfect seeing ~2-3". Much smaller and fainter than A. Dances around a little in the diffraction which makes me worried it's a reflection, but maybe?
16H 19M 55.24S +39° 42' 30.9" P.A. 127 SEP 2.1 MAG 5.50,10.00 SP F3IV-V DIST. 26.38 PC (86.05 L.Y.)

STF 2059: Overlapping disks, notched. Need perfect seeing. [This was 1.2" at Struve's discovery, so easier for him to see -- I doubt he would have found it now, near its closest separation.]
16H 30M 55.71S +38° 03' 52.6" P.A. 178.5 SEP 0.29 MAG 8.75,8.79 SP F5 DIST. 203.25 PC (663 L.Y.)

STF 2024: Pretty orange and blue wide pair, 3 delta mag. B almost blinks like a PN. Faint star 2x further out a 3rd in the system? [No.]
16H 11M 47.60S +42° 22' 28.2" P.A. 44 SEP 22.8 MAG 5.86,10.73 SP K4III DIST. 193.8 PC (632.18 L.Y.)

STF 2030: Nice yellowish pair, 3 delta mag, wide B

STF 2091: Appears round but I "see" rod shape once I know it is 0.4" separation. So can't claim this for the bias. [This one 1.3" at Struve's discovery, so easy for him!]
16H 42M 09.74S +41° 11' 42.9" P.A. 331.2 SEP 0.34 MAG 8.44,9.29 SP F0 DIST. 155.04 PC (505.74 L.Y.)

STF 2025: Wide near equal white pair split in finder, but one has a very faint ~2 delta mag 2-3" companion. Nice!
16H 11M 11.71S +47° 33' 36.1" P.A. 163 SEP 2.6 MAG 8.03,9.75 SP F0 DIST. 141.64 PC (462.03 L.Y.)

16H 33M 54.99S +47° 16' 17.8" P.A. 251 SEP 4.9 MAG 9.00,9.08 SP F5 DIST. 106.61 PC (347.76 L.Y.)

STF 2063: Bright white 2 delta mag B, wide
16H 31M 47.23S +45° 35' 53.8" P.A. 197 SEP 16.3 MAG 5.69,8.70 SP A2V DIST. 69.3 PC (226.06 L.Y.)

52 Her = BU 627: !! Very bright white star with a companion disk 2", 4-5 delta mag. Wow! B illuminated by A. [A,BC seen. BC is equal pair only 0.3 sep. -- maybe try in the 20-inch. 7 stars total in the system]
16H 49M 14.21S +45° 58' 59.9" P.A. 39.6 SEP 2.09 MAG 4.84,8.45 SP A1V DIST. 55.25 PC (180.23 L.Y.) "

STT 313: Clean split, near equal pair. Nice !!

D 15: Light orange elongated, with notch, near equal. [0.9" at discovery]
16H 43M 56.29S +43° 28' 31.2" P.A. 332.8 SEP 0.56 MAG 9.04,9.27 SP K5 DIST. 27.03 PC (88.17 L.Y.)

STF 2015: Very fine orange-yellow A and a more orange B, 1.5 delta mag, ~3" [AB seen; there are two other stars 13.9 mag not seen]
16H 08M 54.75S +45° 21' 11.8" P.A. 160 SEP 2.9 MAG 8.24,9.52 SP F5 DIST. 97.56 PC (318.24 L.Y.)

BU 1198: As much as I want to, I can't see the 14th mag. B star.
16H 19M 44.45S +46° 18' 47.8" P.A. 148 SEP 6.7 MAG 3.89,14.60 SP B5IV DIST. 94.25 PC (307.44 L.Y.)

STF 2082 = 42 Her: Bright orange pair 1 delta mag in finder. The brighter star has a 3-4 delta mag very faint bluish companion, wide separation.
16H 38M 44.89S +48° 55' 41.8" P.A. 93 SEP 27.2 MAG 4.90,11.80 SP M3III DIST. 127.06 PC (414.47 L.Y.)

STF 2093: Bright orange-yellow A, much fainter blue B, very wide separation -- unusual for a Struve to have such a wide sep.
16H 42M 53.76S +38° 55' 20.1" P.A. 265 SEP 116.7 MAG 3.58,11.72 SP G8IIIB DIST. 33.31 PC (108.66 L.Y.)

ES 633. Tried but not seen. B too faint -- a little haze / halo around stars.
17H 01M 33.64S +42° 43' 37.6" P.A. 261 SEP 7.2 MAG 7.34,11.80 SP G5 DIST. 179.53 PC (585.63 L.Y.)

M92. In the area of double star search. Nicely resolved with plenty of stars resolved of different magnitudes. Bright center mist with an overall elongation -- almost like spiral arms with many H2 and star clouds embedded. Tracking platform ran out...
