delta Cep (**)

Name: delta Cep, STFA58
Type: **
Constellation: Cep
Coordinates: 22h29m10.25s / +58°24'54.70"
Components: AC / v4.2 mag / v6.1 mag / 40.9" / 192° / 2016
80mm f/6.25, 25x
Obvious difference in brightness and color. Brighter component slightly orange, weaker blueish. Seems to be little brother of Albireo ;)

LEP103 (**)

Name: LEP103
Type: **
Constellation: Cep
Coordinates: 21h54m14.50s / +66°43'54.20"
Components: v7.2 mag / v8.0 mag / 4.1" / 213° / 2000
152mm f/5.9, 100x, Bortle 4, SQM-L 21.0
The brightness of this double star does not match the data in the WDS. I also couldn't separate anything here. A mistake in the WDS?

STF2807 (**)

Name: STF2807
Type: **
Constellation: Cep

Components: v8.7 mag / v8.8 mag / 1.8" / 311° / 2016
70mm f/5.7, 128x, Bortle 5, NELM 5.7, SQM-L 20.6
Barely split without any noticeable difference in brightness.

STF2840 (**)

Name: STF2840
Type: **
Constellation: Cep
Coordinates: 21h52m01.02s / +55°47'48.30"
Components: AB / v5.6 mag / v6.4 mag / 17.9" / 196° / 2016
55mm f/9.1, 25x
Striking double star with clear distance and difference in brightness.

STF2845 (**)

Name: STF2845

Easy to split with equally bright components.

STF2873 (**)

Name: STF2873
Type: **
Constellation: Cep
Coordinates: 21h58m13.53s / +82°52'10.80"
Components: AB / v7.0 mag / v7.5 mag / 13.4" / 66° / 2016
