STF 12 (**)

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

Components:
m1 m2 ρ θ Year
6m1 7m5 11.5" 148° 2018
Robert Zebahl
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.

STF 22 (**)

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

Components:
m1 m2 ρ θ Year
AB-C 7m1 7m7 3.9" 235° 2017
AB-D 7m1 11m5 66.8" 151° 2005
Robert Zebahl
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).

STF 46 (**)

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

Components:
m1 m2 ρ θ Year
5m6 8m5 6.6" 195° 2015
Robert Zebahl
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.

STF 98 (**)

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

Components:
m1 m2 ρ θ Year
AB 7m0 8m1 20.0" 250° 2018
Robert Zebahl
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.

STF 136 (**)

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

Components:
m1 m2 ρ θ Year
AB 7m3 8m3 15.7" 77° 2016
AC 7m3 13m6 76.9" 312° 2015
AD 7m3 11m6 124.5" 2015
Robert Zebahl
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.

STF 155 (**)

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

Components:
m1 m2 ρ θ Year
AB 7m9 8m0 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 5m2 6m3 23.2" 63° 2018

8" f/6, 37x, Bortle 4-, NELM 5m7+, SQM-L 20.8
Visually evident as double star and easy to find. Well split with slight difference in brightness.
