delta Cep (**)

Name: delta Cep, STFA58
Type: **
Constellation: Cep
Coordinates: 22h29m10.25s / +58°24'54.70"

Components:
m1 m2 ρ θ Year
AC 4.2 6.1 40.7" 192° 2018
55mm f/9.1, 27x, Bortle 6
At 27x easy to separate, rather wide apart with clear difference in brightness. At 38x the colours are slightly better visible: A shines in bright orange, B appears rather gray-blueish.

80mm f/6.25, 25x
Obvious difference in brightness and color. Brighter component slightly orange, weaker bluish. Could be Albireo's little brother ;)

H1 48 (**)

Name: H1 48
Type: **
Constellation: Cep
Coordinates: 21h13m42.46s / +64°24'15.10"

Components:
m1 m2 ρ θ Year
7.2 7.3 0.7" 244° 2018
152mm f/5.9, 270x, Bortle 6-
Clearly elongated, of equal brightness with partly visible, slight constriction.

LEP103 (**)

Name: LEP103
Type: **
Constellation: Cep
Coordinates: 21h54m14.50s / +66°43'54.20"

Components:
m1 m2 ρ θ Year
7.2 8.0 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?

STF2675 (**)

Name: STF2675, kappa Cep, 1 Cep
Type: **
Constellation: Cep
Coordinates: 20h08m53.32s / +77°42'40.90"

Components:
m1 m2 ρ θ Year
AB 4.4 8.3 7.2" 120° 2003
55mm f/9.1, 38x, Bortle 6
At 27x faint companion not visible. At 38x and higher magnification the companion is quite easily visible as faint, tiny star. Very nice, uneven pair!

STF2807 (**)

Name: STF2807
Type: **
Constellation: Cep
Coordinates: 21h17m33.47s / +82°31'03.70"

Components:
m1 m2 ρ θ Year
8.7 8.8 1.9" 309° 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:
m1 m2 ρ θ Year
AB 5.6 6.4 17.7" 197° 2018
55mm f/9.1, 25x
Striking double star with clear distance and difference in brightness.

70mm f/5.7, 22x, Bortle 6-
Striking, beautiful double star with visible difference in brightness. At 44x A appeared rather yellowish, B slightly blueish, whereby the colors were difficult to detect.

STF2845 (**)

Name: STF2845
Type: **
Constellation: Cep
Coordinates: 21h52m20.95s / +63°06'04.50"

Components:

AB 8.1 8.2 2.0" 173° 2016
70mm f/5.7, 128x, Bortle 4-, SQM-L 20.9
Easy to split with equally bright components.
