STF12 (**)

Name: STF12, 35 Psc
Type: **
Constellation: Psc
Coordinates: 00h14m58.84s / +08°49'15.50"

Components:
m1 m2 ρ θ Year
6.1 7.5 11.5" 148° 2018
70mm f/5.7, 22x, Bortle 6, SQM-L 19.1
At 22x pretty bright but uneven pair with relatively close components. At 44x the brighter component looked slightly yellowish, the fainter one slightly blueish. The double star could be observed together with STF22 (38 Psc) in the same field of view and stands in nice contrast to it.

STF22 (**)

Name: STF22, 38 Psc
Type: **
Constellation: Psc
Coordinates: 00h17m24.50s / +08°52'34.80"

Components:
m1 m2 ρ θ Year
AB-C 7.1 7.7 4.0" 235° 2016
AB-D 7.1 11.5 66.8" 151° 2005
70mm f/5.7, 44x, Bortle 6, SQM-L 19.1
AB-C: At 44x separated with almost touching diffraction disks and small difference in brightness. At 57x clearly separated, but still quite close together. It stands in beautiful contrast to the nearby double star STF12 (35 Psc).

STF46 (**)

Name: STF46, 55 Psc
Type: **
Constellation: Psc
Coordinates: 00h39m55.57s / +21°26'18.60"

Components:
m1 m2 ρ θ Year
5.6 8.5 6.6" 192° 2014
70mm f/5.7, 44x, Bortle 6, SQM-L 19.1
Clearly separated, but large difference in brightness. The companion appeared only as a tiny, faint star. The primary component sparkled in light orange.

STF98 (**)

Name: STF98
Type: **
Constellation: Psc
Coordinates: 01h12m52.98s / +32°04'31.70"

Components:
m1 m2 ρ θ Year
AB 7.0 8.1 19.6" 249° 2016
70mm f/5.7, 22x, Bortle 6, SQM-L 19.1
Easy to separate at 22x, clear difference in brightness at moderate distance. In terms of color, the two components appeared slightly different. At 44x A appeared white-yellowish, B slightly reddish.

STF136 (**)

Name: STF136, 100 Psc
Type: **
Constellation: Psc
Coordinates: 01h34m51.61s / +12°33'31.20"

Components:
m1 m2 ρ θ Year
AB 7.3 8.3 15.7" 77° 2016
AC 7.3 13.6 76.9" 312° 2015
AD 7.3 11.6 124.5" 2015
70mm f/5.7, 22x, Bortle 6, SQM-L 19.1
AB: At 22x easy to separate with well visible difference in brightness. A difference in color is visible, but the assignment of colors was difficult. At 44x A appeared slightly orange, B rather blueish.

STF155 (**)

Name: STF155
Type: **
Constellation: Psc
Coordinates: 01h44m15.19s / +09°29'02.70"

Components:
m1 m2 ρ θ Year
AB 7.9 8.0 4.9" 325° 2018
70mm f/5.7, 44x, Bortle 6, SQM-L 19.1
Lovely embedded in a small group of stars. The components showed a small difference in brightness and were very close together.

zeta Psc (**)

Name: zeta Psc, 86 Psc, STF100
Type: **
Constellation: Psc
Coordinates: 01h13m43.80s / +07°34'31.80"

Components:
m1 m2 ρ θ Year
AB 5.2 6.3 22.8" 64° 2018
8" f/6, 37x, Bortle 4-, NELM 5.7+, SQM-L 20.8
Visually evident as double star and easy to find. Well split with slight difference in brightness.
