2020-04-05: The pair AB stands out immediately and shows itself in beautiful colors: A white-yellowish, B slightly orange. Almost at right angles to pair AB component C is visible as a faint star at a slightly smaller distance. I did not pay attention to the even fainter component D. |

2020-04-05: Components A, B and C easily visible with decreasing brightness. I did not consider component D. A: white-yellowish, B: pale orange. I liked the view in the 8x40 binoculars better. |

Binoculars with internal stabilisation, handheld. AB cleanly split with distinct difference in magnitudes. Strong visual presence of this physical double is enhanced by the complete lack of visual competition in 4.5° FOV. Interesting to contemplate that in the 9th century AD Struve 1694 was just as close to the celestial north pole as Polaris (also a physical double) is today. Also known as 32H Cam, which comes from the celestial map produced by Johannes Hevelius in the late 17th century. |

AC, Mizar/Alcor: After seeing the two stars separated for the first time under clear corona skies in spring 2020, this became a regular and easy sighting. Naked-eye star splitting is a skill that develops rapidly with practice. Mizar and Alcor are wide apart with my 60-year-old eyes, and occasionally Alcor appears slightly bluish. |

AB: 2020-04-12: Observation from city with a 70/400mm ED refractor, for which I made aperture masks from 10mm to 60mm. Goal was to find the minimum magnification for a successful split.
70mm: At 12.5x no separation of the components possible due to outshining. Grey filters brought a slight improvement, but again no separation or elongation was visible.
60mm: At 12.5x slight outshining of the companion, clearly elongated and almost separated.
50mm: At 12.5x the companion was almost outshined. A separation was just possible.
40mm: At 12.5x both components appear finely separated from each other.
30mm: At 10x not clearly separable due to outshining, but clearly elongated. At 12.5x then quite easy to separate with a fine star rendition.
20mm: At 10x the companion is still clearly visible, but quite close to the primary component. At 12.5x best view under the used apertures with a very fine rendition!
10mm: At 10x the companion appears very faint. Separation possible, but extremely tight. At 12.5x reasonably well separated. |

70mm (22x) |
AB: 2020-04-11: At 12x no separation possible, because the bright primary component outshines the companion. At 22x clearly separated, but still quite close together. |

At a position angle of roughly 265° I had the feeling something was going on; a kind of protusion of the primary, coming and going. 200x: yes, now a stellar condensation kept popping in and out of sight at the same position, just on the outside of the first ring, which itself was coming and going in not-so-perfect seeing. Upping the magnification to 240x and 300x didn't improve the view. |

STF1831 (AC): Wide split at 7x but still a very distinct impression of being a double. No colour impression. Two fine pinpricks of light, rather attractive in 8° FOV.
According to Stelledoppie the A-C pair, at 509 light years distance to us, is the only physical pair in the whole STF 1830/1831 comples. A nice physical double for small binoculars. |

STF1831 (AC): 2020-04-05: Fairly wide pair with slight differences in brightness and color. C appeared slightly orange, A on the other hand slightly bluish. Comparatively bright double star, which gives a nice view. |

2020-04-11: At 22x the components AB, C, E & F are well visible and widely separated. E & F are comparatively faint. The C component in the middle appeared white-yellowish, AB rather white with a slight tendency to blue. At 57x, the pair AB with a clear difference in brightness can be easily split. An altogether rewarding and unusual multiple system. |

AC: bei 72x fällt die helle Komponente C im Südwesten von AB zwar auf, ich hätte aber nicht vermutet, dass der Stern dazu gehört |

bei 20x sind alle drei Komponenten direkt erkennbar - die mittlere Komponente B steht leicht südlich versetzt und scheint der schwächste von den Dreien zu sein - bei 32x sind alle drei Sterne gut getrennt und C steht näher zu B als A - Farbe ist nicht wirklich feststellbar, aber der C strahlt ein wenig klarer (nicht heller), A und B wirken etwas dumpfer, fast so als würden sie zum Orange tendieren |
|

With more time observing & getting used to the image, and in moments of better seeing, the notch became more distinct. It would not separate in spite of moments of better seeing. I could also see the elongation, but only subtly notched due to the smaller scale, at 667x |

naked eye |
AB: Noticed with naked eye and without prior PA knowledge that a secondary was flickering next to Zubenelgenubi. Unexpected and first naked-eye sighting. Checked position with binoculars to be sure. Further naked-eye look at Mizar/Alkor (Zeta UMa) to gauge my momentary acuity and assess the difference to Alpha Lib. Zeta UMa more easily and widely split than ever before, and Alkor appeared for the first time bluish, so this was an exceptional night for naked-eye double-star splitting. Three-star rating awarded because Zubenelgenubi is the second-best naked-eye true-physical double star in the summer sky after Mizar/Alkor. |

Hier handelt es sich um ein Dreifachsternsystem, welches jetzt aber nicht durch eine besondere Färbung der Sterne auffällt. Die A - B/C Komponenten stehen noch sehr weit auseinander, wobei auch die A-Komponente um einiges heller erscheint. Die beiden Komponenten B/C sind wesentlich näher beieinander und unterscheiden sich auch kaum in ihrer Helligkeit. |

Stabilised binoculars, handheld. Difficult handheld in this instrument, but clearly split and attractive as such. Tripod mounting would surely help and make the difference for a nice pair for this magnification. One of the earliest doubles split, found by Benedetto Castelli in 1627, but according to Stelledoppie not a physical double (in contrast to the very tight BU 947 AB pair in the system, which is physical, with a separation of 0.3” in 2020 and 0.4” in 2030 – and the wide PWL 9001 AD pair with a separation of 518” – A, B and D are thus a physical triple). “H“ in the catalogue name means that this double star is listed in the catalogue of W. Herschel. The 3 in the name means that it is a double star of the 3rd Class [separation 5'' - 15''] in Herschel’s system. |

bei 64x zeigt sich das Pärchen in guten Momenten knapp getrennt - bei 107x wird Komponente B besser sichtbar, er wirkt gräulich wie ein halbdurchsichtiger Geist - die Trennung ist nun eindeutig, aber immer noch knapp - großer schwer einschätzbarer Helligkeitsunterschied zwischen A und B, gut 2.5 Größenklassen Differenz habe ich in der Nacht geschätzt, Treffer |

I sensed elongation with the 8 inch mask at 333x, but it was a haze only flashing elongation with averted vision. With the 20 inch the a star resolved, orange, and the B was noticed at 3" but was considerably fainter, I would guess 1.5 to 2 delta mag. |

Very interesting. At 20 inch the a star was orange and bloated with the seeing, did not notice a pair. I used the 8 inch mask which tightened the A star up considerably, then with averted vision could discern a very faint small glow in one particular direction, but could not hold it direct. Back to the 20" and now in good moments I can see the B star quite well, 5 delta mag, bluish. 333x |

Awesome! clean split, very clean star images. Split by half disk, half delta mag. very cool great catch! suspected at 667x, ramped up power to 1067x to split. |

bei 64x ist erkennbar, dass A einen Begleiter nordöstlich hat, eine kleine Einschnürung zeigt sich - beide Komponenten sind relativ schwach - bei 107x ist mit etwas Konzentration Komponente B knapp getrennt von A erkennbar - B ist halb so hell wie A |

Extremely fine pair, brightens and elongated with averted vision but it's better to let the seeing settle down the hazy refraction and can see points of stars. |

90 Her. Need stillness, it coalesces from the diffraction to a light orange point at 553x (grey at 885x). No doubt about it, star, point light. For the first 10 minutes of observing seeing allowed me to glimpse it 1 of every 10 seconds. But after a while seeing was better and I could hold it pretty consistently in both magnifications. At 553x it's in the first ring, at 885x it's in the second. |

Komponente B ist knapp getrennt westlich von A erkennbar - Helligkeitsunterschied eine halbe Magnitude (1.17 mag laut Stelle Doppie) - der Doppelstern muss sich gegen viele helle Sterne im Umfeld durchsetzen, er wirkt dadurch ein wenig verloren, aber auch filigraner |
