STF2016 (**)

Name: STF2016
Type: **
Constellation: Her
Coordinates: 16h12m07.05s / +11°54'39.20"
Components: v8.5 mag / v9.6 mag / 7.4" / 148° / 2015
Only 11 arcminutes northwestward is the pretty bright planetary nebula IC4593.

120mm f/5, 40x, Bortle 4, SQM-L 21.0
SQM-L 20.6: Split at 40x with obvious difference in brightness. At 75x easily split.

STF2140 (**)

Name: STF2140, alpha Her
Type: **
Constellation: Her
Coordinates: 17h14m38.86s / +14°23'24.90"
Components: AB / v3.5 mag / v5.4 mag / 4.8" / 104° / 2016
55mm f/9.1, 41x
Well split with noticeable difference in brightness.

STF2161 (**)

Name: STF2161, 75 Her, rho Her
Type: **
Constellation: Her
Coordinates: 17h23m40.97s / +37°08'45.30"
Components: AB / v4.5 mag / v5.4 mag / 4.1" / 320° / 2016
55mm f/9.1, 38x
Very nice view. Easily split with visible difference in brightness. Pretty tight. Both components appeared white. The double star forms with two other, fainter field stars a conspicuous, acute-angled triangle, whereby the double star marks the tip.

STF2280 (**)

Name: STF2280, 100 Her
Type: **
Constellation: Her
Coordinates: 18h07m49.56s / +26°06'04.40"
Components: AB / v5.8 mag / v5.8 mag / 14.4" / 183° / 2016
120mm f/5, 40x, Bortle 5+, SQM-L 20.8
SQM-L 20.5: Very nice, evident double star with equally bright components.

152mm f/5.9, 22x, Bortle 3-, SQM-L 21.3
Beautiful view. Easy to separate with components of the same brightness. It is noticeable that there are no brighter stars in the immediate vicinity, so that the double star stands out very well.
