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 bluish. 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:

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"

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 88 (**)

Name: STF88, psi 1 Psc, 74 Psc
Type: **
Constellation: Psc
Coordinates: 01h05m40.93s / +21°28'23.60"

AB: 2020-11-25: Beautiful! Very nicely separated with little difference in brightness. White-yellowish & white-bluish. Separable even without using a tripod, but difficult.

STF 90 (**)

B 8x44
AB: 2020-11-25: On this evening nicely visible together with Mars in one field of view. The double star forms a nice triangle with two other stars. It is clearly separable with a fainter companion. A appeared rather cool in color, the companion somewhat warmer. Very nice sight.

STF 98 (**)

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

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"

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 bluish.

STF 155 (**)

Name: STF155
Type: **

Lovely embedded in a small group of stars. The components showed a small difference in brightness and were very close together.
