more hercules doubles

Out again last night, but only for an hour due to a late start.  The sky seemed a little hazy and seeing was not as good, merely 7/10.  Doubles around Epsilon and Omega Hercules, Big Blue (11.5-inch) 553x throughout.

STT 585 = 41 Her: Orange with very much fainter wide B.  Surely not a binary. A range of 4 stars about, maybe should be considered an open cluster.  [WDS says 4 stars but with 5 pairings -- a confused mélange]
16H 44M 59.98S +06° 05' 17.3" P.A. 191 SEP 162.9 MAG 6.66,10.40 SP K0V+K3V DIST. 45.87 PC (149.63 L.Y.) 

ENG 56: Orange and very wide 3 delta mag B.  A 3rd star making a triangle, triple? [Confirmed triple] 
16H 15M 59.88S +11° 25' 30.6" P.A. 252 SEP 62.2 MAG 7.37,10.60 SP K0 DIST. 276.24 PC (901.09 L.Y.)

STF 2062:  B pops into view with seeing, 2-3", 2 delta mag, very fine!  Must've been a great night for old Wilhelm to pick this up. 
16H 34M 44.14S +08° 45' 54.2" P.A. 108 SEP 2.4 MAG 9.07,10.61 SP G0

SHJ 239 = 43 Her: Bright orange and 4x fainter B, very wide separation. [AB seen; BC a faint and wide, I would not assume it was related] 
16H 45M 49.89S +08° 34' 57.3" P.A. 229 SEP 84.1 MAG 5.33,9.29 SP K5III DIST. 108.58 PC (354.19 L.Y.) 

STF 2051: Orange and blue, wide separation, 2 delta mag. 16H 29M 25.06S +10° 35' 31.4" P.A. 19 SEP 13.8 MAG 7.68,9.42 SP G5III DIST. 218.82 PC (713.79 L.Y.)

BU 625 = Omega Her: Bright white and much fainter B, ~5 delta mag, wide. [4x system.  AC seen.  AB is 11.5 and 0.8" -- very tough, should try it in the 20-inch.  AD 12.58 and super wide] 
16H 25M 24.93S +14° 02' 00.3" P.A. 89 SEP 25.8 MAG 4.58,11.76 SP B9PCR DIST. 76.69 PC (250.16 L.Y.)

STF 2083: Near equal wide.  [AB seen, AC 11th mag & super wide -- how think it was related and not line of sight?] 
16H 42M 44.12S +13° 36' 29.4" P.A. 334 SEP 12.7 MAG 9.13,9.56 SP G5V+G9V 

STF 2037:  Very small elongated haze with two brightenings resolving to points with seeing.  [1.6" at discovery, 1.1" now] 
16H 18M 49.03S +17° 23' 58.3" P.A. 257 SEP 1.1 MAG 9.82,9.86 SP G5 DIST. 167.5 PC (546.38 L.Y.)

STF 2107: !! This was a CDSA plot find, didn't expect it to be special.  Yellow and orange pair, very close ~1.5", 1 delta mag.  Very pretty. [AB seen, AC nearly 12th mag and super wide] 
16H 51M 50.10S +28° 39' 58.7" P.A. 106 SEP 1.39 MAG 6.90,8.50 SP F5IV DIST. 58.41 PC (190.53 L.Y.)

STF 2098: 4 stars in an arc; assume AB is the closer pair ~1 delta mag.  All wide. [5 stars in 5 pairings] 
16H 45M 43.47S +30° 00' 17.2" P.A. 145 SEP 14.3 MAG 8.77,9.61 SP F2V DIST. 89.69 PC (292.57 L.Y.)

BUP 174: Bright and very much fainter B, wide separation.  Not binary? [confirmed not physical]
