more hercules doubles

Out in the back yard last night with Big Blue again, chasing some doubles in eastern Hercules.  Seeing was only average 6/10 and transparency a hazy 3/5, some dewing.  A little more than an hour's session, with a couple BUs for highlights.  Toward the end of the night, around 10:30pm, the owl's screech was very loud overhead but I didn't see it.  Flocks of Canada geese were settling into the creek.  And a nice surprise, the highway noise was not too loud.

STF 2411: 553x.  Pretty orange A with 2 delta mag fainter B, ~7", a couple other stars in the view.  [Couple other stars might be WAL 97 but they seem fainter than what I sketched.]

18H 52M 18.63S +14° 32' 08.0" P.A. 95 SEP 13.5 MAG 6.63,9.61 SP G9III DIST. 111.11 PC (362.44 L.Y.) 

HU 676: 553x.  Nice orange star but nothing certain seen.  Suspected a very faint star ~10" but had only a couple of glimpses of it with averted vision. [Not seen, separation only 1.3"]

18H 57M 11.56S +14° 49' 58.9" P.A. 80 SEP 1.3 MAG 7.26,10.34 SP G5 DIST. 212.31 PC (692.56 L.Y.)

BU 641: 553x.  !! Extraordinary!  Moderately bright A and very much fainter B, 4-5 delta mag, <1" separation.  Seeing needs to still.

18H 21M 48.44S +21° 30' 27.9" P.A. 341 SEP 0.8 MAG 7.03,8.66 SP B9.5II DIST. 264.55 PC (862.96 L.Y.)

109 Her:  553x.  Pretty orange-yellow star.  Disk not quite round, but I don't notice any obvious pair. [AB = STT 587 a nearly 12th mag wide pair, not seen, along with spectroscopic pair or another faint/wide, AC] 

18H 23M 41.85S +21° 46' 11.0" P.A. 323 SEP 237.2 MAG 3.98,11.06 SP K2.5IIIAB DIST. 36.47 PC (118.97 L.Y.)

111 Her = ENG 64: 553x.  Nothing suspected except a string of three stars widely separated. [String is likely AB, AC, and AD.  Also a BC and a DJ -- equal wide pair.  Ten visible stars, I don't know why they just don't call it an open cluster?] 

18H 47M 01.26S +18° 10' 53.4" P.A. 241 SEP 110.6 MAG 4.36,11.60 SP A5III DIST. 28.89 PC (94.24 L.Y.)

110 Her = HJ 2839: 553x.  Fairly bright A, B flashes to view with averted vision but held with direct.  [Assume I saw AC as it was the brightest of four pairings, though the separation seems wider than what I sketched...] 

18H 45M 39.72S +20° 32' 46.7" P.A. 59 SEP 73 MAG 4.19,12.60 SP F6V DIST. 19.21 PC (62.66 L.Y.) 

STF 2415: 553x.  Pretty ruddy A and blue B, ~2", ~2 delta mag

112 Her = ISO 8: Nothing seen except the bright star. 

18H 52M 16.43S +21° 25' 30.6" P.A. 138 SEP 0.2 MAG 5.48, SP B9II-IIIP DIST. 124.38 PC (405.73 L.Y.)

STF 2401: 553x.  Not difficult, reddish A and blue B, ~5", 1 delta mag.  [AB seen, AC fainter and wider.] 

18H 48M 57.83S +21° 10' 01.3" P.A. 38 SEP 4.3 MAG 7.27,9.27 SP B3V DIST. 2941.18 PC (9594.13 L.Y.)

STF 2310: 553x.  ~3", 2 delta mag.  Nice pair. 

18H 20M 38.67S +22° 47' 50.7" P.A. 237 SEP 5 MAG 6.83,9.98 SP B8III DIST. 302.11 PC (985.48 L.Y.)

STF 2280 = 100 Her: 553x.  Very bright near equal white.  [AB seen; AC fainter and wider.]

BU 640: 553x.  Suspect very faint B with averted vision only, pretty wide.  [Missed.  0.7" but at 14th mag I didn't have a chance -- maybe with the 20-inch.] 

18H 20M 49.23S +27° 31' 48.3" P.A. 322 SEP 0.7 MAG 7.00,12.00 SP G1V DIST. 28.55 PC (93.13 L.Y.)

STT 359: 553x.  Nice!  ~0.8" equal yellow-orange stars. 

18H 35M 30.40S +23° 36' 19.9" P.A. 4 SEP 0.75 MAG 6.35,6.62 SP G9III-IV DIST. 144.3 PC (470.71 L.Y.)

113 Her = BU 646: 553x.  Nice orange star but nothing noticed. [MKT 9 spectroscopic; missed the BU.  Three visible stars, AB, AC, BC, doing a dance.] 

18H 54M 44.88S +22° 38' 42.3" P.A. 37 SEP 34.4 MAG 4.59,11.10 SP G4III DIST. 144.72 PC (472.08 L.Y.)

18H 27M 45.89S +24° 41' 50.8" P.A. 1 SEP 0.9 MAG 7.14,8.90 SP B9V DIST. 256.41 PC (836.41 L.Y.)

STF 2259: 553x.  Orange and slightly blue tnged B, 2 delta mag, wide, 15" or more.  

17H 59M 03.63S +30° 02' 56.1" P.A. 278 SEP 19.8 MAG 7.27,8.44 SP G5II DIST. 446.43 PC (1456.25 L.Y.)

99 Her = AC 15: 553x.  Faint point seen in the diffraction of brighter star disk.  Two faint very wide stars in view. [7 star stystem, AB seen which is AC 15.  What is plotted in CDSA as AC 15 seems to be a different pair, maybe part of this sprawling system.] 

18H 07M 01.61S +30° 33' 42.7" P.A. 328.6 SEP 1.38 MAG 5.13,8.96 SP F7V DIST. 15.64 PC (51.02 L.Y.) 

ES 471: 553x.  Much fainter B star, 3 delta mag, wide separation.  Direct vision, but faint.  [AC seen.  AB in other direction, nearly the same separation, but much fainter still.  Six stars in the system.] 

18H 04M 39.08S +27° 06' 54.9" P.A. 44 SEP 24.5 MAG 7.21,10.20 SP A7III DIST. 169.2 PC (551.93 L.Y.)

STF 2315: 553x.  Near contact / overlapping disks, 0.5 delta mag.  [AB seen: a very good catch considering 0.6" separation.  5 stars in system, faint and far.] 

18H 24M 58.46S +27° 23' 41.3" P.A. 116.2 SEP 0.61 MAG 6.57,7.77 SP A0V+A4V DIST. 117.51 PC (383.32 L.Y.)
