erst bei 320x ist Komponente B knapp getrennt nördlich von A zu erkennen - beide Sterne sind relativ hell und haben relativ große Beugungsscheibchen, so dass die Trennung nur knapp zu sehen ist - nicht wirklich schön, wenn man in den Nächten vorher mit einem Refraktor Doppelsterne beobachtet hat |

Split at 533x but used barlow to confirm the PA accurately since this is a short period pair. Nicely split orange stars, half delta mag. Seeing it now at nearly the furthest extent of its orbit, it will become more difficult with time. The pair is a "mere" 55.91 lightyears away |

A ist gelblich. B fiel sofort ins Auge, auch bei 144x. C war extrem schwierig. A musste außerhalb des Gesichtsfeldes stehen, aber auch dann war er nur indirekt sichtbar. Dann aber überraschte der verhältnismäßig große Abstand B-C. ~ A ist ein Hauptreihenstern ähnlich der Sonne. B ist ein weißer Zwerg, einer der hellsten am Himmel. C ist ein Roter Zwerg, davon gibt es nicht viele in der Reichweite kleiner Instrumente. Insgesamt hat man drei Zwergsterne auf einen Blick: Einen gewöhnlichen (=Hauptreihen-) Zwerg, einen weißen und einen roten. |

At 57x nothing seen at first sight. At 133x the much fainter component was visible after a short time as a tiny star in the correct position angle. With this knowledge, the observation at 57x was also successful, even if one has to look very closely. The challenge here is not so much the angular distance as the large difference in brightness. |

Already comparatively easy at 180x. The faint companion can be seen well as a quite distinct, slightly elongated, partly round brightening. At 225x and above it becomes easy and immediately apparent, even if the diffraction rings of the primary component are not permanently visible due to the seeing. The primary component was shining in a bright orange. |

AB: Both components A + B clearly split, whereby the diffraction rings where merged together. A very nice view together with component C. I sketched this triplet, which reflects my impression well. Unfortunately, the distance and position angle are not particularly well observed. Also the difference in brightness I didn't noticed during my observation. |

At 28x the pair AC is nicely separated without any problems. The close pair AB is already recognizable at 86x as a clear figure '8', at 125x wonderfully separated. The components A & B appear yellowish. Very nice view together with STF 946 in one field of view! |

At 49x the pair AC is beautifully separated with a significant difference in brightness. At 100x, the close pair AB is also separated, although still very close together. A slight difference in brightness is noticeable. At 129x, the view is magnificent. The two bright components A & B present themselves yellowish, the fainter component C rather greyish. STF 948 can be well observed in a field of view with the neighbouring double star STF 946. Both show a nice overall scenery. |

152mm (150x) |
AB: 2020-03-19: At 150x the clearly fainter companion is visible as a roundish brightening. Due to the chromatic aberration of the achromat (152mm f/5.9) the companion is almost outshined. At 180x the companion is then well, at 225x and 300x very well visible as a tiny separated star. |

AB: Zeta Boo. Short period. First impression was moderately well notched overlapping disks (eg. not barely notched, but not strongly notched either). 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 |

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. |

bei 64x sind die Sterne so schwach, dass ich hellere Sterne im Umfeld zum Fokussieren nutzen muss - beide Komponenten sind als 8 erkennbar, die Einschnürung ist aber nur in guten Momenten da - bei 107x dann gelingt die Trennung, B wirkt deutlich schwächer (in Wirklichkeit ist B nur 0m4 schwächer), aber vielleicht liegt es daran, dass die beiden Sterne ohnehin nur sehr schwach beobachtbar sind - das hat wenig Freude bereitet |

naked eye |
While waiting for Comet Neowise at 3 in the morning in July 2020 surprised myself with my first naked-eye separation of Alpha1 und Alpha2 Capricornis (observing site at 50° northern latitude, Alpha1/2 passing through meridian). Encouraged by this, I lay down and had a close look at Epsilon Lyrae, without really expecting to be able to split it naked-eye, having never succeeded previously. At first Epsilon Lyrae appeared as a very short dash of light. Then the dash resolved into two pinpoints. After 15 years in the hobby and at age 60, at last got Eps Lyr split! No precise prior PA knowledge. After memorising PA as seen naked-eye carefully, confirmed it with binoculars. Eps Lyr is the third-easiest physical double in the (northern hemisphere) summer sky for the naked eye, after Zeta UMa (much easier) und Alpha Lib (marginally easier). |

At 22x almost separated. The double star appeared strikingly orange and forms a conspicuous, nearly isosceles triangle with neighbouring stars. At 44x clearly separated, relatively close together with a small difference in brightness. |

Observed at magnifications between 129x and 300x. The seeing and transparency (Bortle 6-) were only average. The rather faint B component seemed to appear in few moments. |
|
Robert Zebahl
Leipzig (Germany) |
152mm (150x) |
The seeing was more average (3/5). Observation under suburban conditions (Bortle 6, SQM-L 19.1). Initially observed at 270x, later at 300x. The extremely faint companion was always visible at the same position if the air was steady enough. Difficult because of the low magnitude! |

A1469 (CD): das Paar gehört zum interessanten Mehrfachsystem STF2922 - während bei 32x Komponente C nur knapp sichtbar ist, zeigt sich D wieder deutlicher - Abstand CD ist doppelt so groß wie BC (STF2922) |
|
Rene Merting
Drachhausen (Germany) |
100mm (32x) |
STF2922 (AB): AB: bei 32x sind beide Komponenten gut getrennt sichtbar - B im Süden ist eine halbe Größenklasse schwächer
BC: bei 32x schimmert südöstlich von der Komponente B ein ganz schwacher Lichtpunkt, die Komponente C, durch - Komponenten BC mit gleichem Abstand wie AB
nachrichtlich zu D: interessant ist das Mehrfachsystem allemal, denn in doppelter Entfernung weiter südöstlich steht eine vierte Komponente D (eigene Bezeichnung: A1469, D mit Helligkeit 9.08 mag), so dass 4 Sterne problemlos mit dieser Öffnung zu erfassen sind |
