Transparency was hurt by thin clouds, and seeing was not good enough for full aperture, so spent some time masked to 7-inches. Since twilight lasts so long I observed for a little more than an hour. Hoping for better weather the rest of this week.

STF1680 AB; 178; 205x: B seen with averted vision at first then I could hold it with direct, well separated, faint pair.
12h 49m 12.97s +21° 46' 30.0" P.A. 335.00 sep 2.9 mag 9.40,11.60 Sp G0

STF1707 AB: 178; 205x: B is wide and faint, seen with averted vision at first and held direct after foveal coaxing
13h 01m 14.16s +15° 51' 45.2" P.A. 41.00 sep 8.3 mag 9.70,11.50 Sp G0

STF1759 AB: 178; 205x: Faint and wide B.  Physical per WDS but my calculator shows there's no parallax overlap, 1 AU too far apart. 
13h 33m 44.39s +27° 27' 00.5" P.A. 155.00 sep 10.4 mag 9.87,11.22 Sp G5 dist. 74.4 pc (242.69 l.y.)

RX Boo 178; 205x: One of John Herschel's red stars, which he described as "Vivid red, almost a bright ruby colour, fine."  It appears noticeably orange-red, easily picked out in the field. 

STF1816 AB: 178; 533x: Notched elongation, unequal pair, seeing won't support higher magnification.  Physical with 1340-year period, it is near periastron now and will remain there the rest of my lifetime.
14h 13m 54.63s +29° 06' 19.5" P.A. 101.00 sep 0.3 mag 7.43,7.75 Sp F0+A2 dist. 113.38 pc (369.85 l.y.)

STF1931 AB: 178; 205x: Widely separated white stars.  WDS has as physical and my calculator agrees, though there is no orbit as yet.

15h 18m 41.98s +10° 25' 39.7" P.A. 166.00 sep 13.4 mag 7.20,8.07 Sp F7V+G3V dist. 49.98 pc (163.03 l.y.)

POU3145 AB: 178; 205x: Near equal wide white stars.  WDS lists as physical, and I agree.
13h 37m 02.85s +23° 18' 31.8" P.A. 200.00 sep 5.7 mag 10.06,10.11 Sp F8
