AB: 20x reicht zwar schon für eine klare Trennung, aber Komponente B im Osten ist nur dumpf grau-blau und noch zu schwach für den schönen Farbkontrast, der sich bei 32x offenbart - Komponente A strahlt dann in einem satten Bernsteingelb, B im Osten gibt sich unterkühlt bläulich - Helligkeitsunterschied 1 bis 1.5 Größenklassen, schwierig abschätzbar wegen der Farben |

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 |

100mm (32x) |
AB: bei 32x ist Komponente A so hell, dass B trotz des augenscheinlich großen Abstandes von 13,4" nur knapp getrennt zu sehen ist - Komponente A ist gleißend hell-gelb, B dürfte mindestens 3 Größenklassen schwächer sein und wirkt dadurch dumpfer |

At 56x the color difference was very evident: The brighter component appeared slightly yellowish, the fainter one slightly bluish. Highly recommended!

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. |

AB-C: bei 64x zeigt sich Komponente C ganz schwach südwestlich von AB
AB-D: bei 32x schließt sich an die zartgelbe Komponente AB unmittelbar im Osten dicht stehend D weißorange an - ein schickes Trio zusammen mit E weiter östlich
AB-E: bei 32x zeigt sich in vierfacher Entfernung von AB-D die Komponente E weiter östlich in einer Linie - E ist ähnlich hell wie D |

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. |

A-BC: bei 32x ein wunderschöner eng stehender Doppelstern - die bei dieser Vergrößerung noch nicht trennbare Komponenten B und C im SO wirken leicht gelblich und ist leicht heller als A - die Komponenten A und BC wollen sich berühren, schaffen es aber nicht ;-)
BC: bei 64x wirkt BC leicht länglich wie ein Stäbchen - bei 107x dann der Aha-Effekt, es sind zwei Sterne, knapp getrennt und mit gleichem Positionswinkel wie A-BC - beide Komponenten B und C sind gleich hell und einzeln jeweils etwa eine halbe Größenklasse schwächer als A im NW |

At 22x, the components A, B and CD are immediately conspicuous, where A dominates. They form a beautiful, acute-angled triangle. At 69x, color differences are also visible. A: subtle orange; B: grey-bluish; CD: tendency to orange. Rewarding, because the double stars STF 928 & STF 929 as well as the very conspicuous carbon star UU Aur are in close proximity and can partly be observed together in one field of view! |

AB: Tight but nicely split at 25x. No colour whatsoever seen. A appears brighter than B, whereby the data do not support this – perhaps a product of different (yet not seen) colouration? According to Stelledoppie not a physical pair. Attractive together with Struve 1349 in same field of view. |

AC: bei 32x bildet STF1350 AB mit vier ähnlich hellen Sternen westlich ein Muster, ähnlich einer Sense - der erste der vier Sterne bzw. der nächststehende Stern südsüdwestlich mit mehr als zehnfachem Abstand AB ist Komponente C, er ist schätzungsweise eine halbe Größenklasse schwächer |

At 22x, all three components are already visible, with A & B still standing quite close together. Component C is less prominent. At 69x and 100x, the pair AB shows a nice color contrast: The eastern component mostly appeared in a slightly shiny orange, while the other component appeared more white-bluish. During the observation, however, the colors changed between both components. At the time of observation, the pretty bright comet C/2019 Y4 Atlas was also in the same field of view - a great scene! Note to the sketch: The positions of the stars to each other do not exactly match, also the alignment of the pair AB to C. |

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. |

Robert Zebahl
Leipzig (Germany) |
60mm (160x) |
AB: 2020-03-16: 102/1122mm ED refractor stopped down to 60mm. The diffraction ring of the primary component is virtually invisible. The companion appears only in few moments as an extremely faint, elongated brightening in the diffraction ring. Very difficult. Telescope should be in very good optical condition! |

Leipzig (Germany) |
70mm (160x) |
AB: 2020-03-16: 102/1122mm ED refractor stopped down to 70mm. Companion only visible as a subtle, elongated, not permanently visible brightening. The diffraction ring of the primary component is only visible occasionally. Difficult. Telescope should be in good optical condition! |

Leipzig (Germany) |
80mm (160x) |
AB: 2020-03-16: 102/1122mm ED refractor stopped down to 80mm. Companion permanently visible as elongated brightening in the diffraction ring. But the diffraction ring itself appears rather faint. Moderately difficult. |

Robert Zebahl
Leipzig (Germany) |
90mm (160x) |
AB: 2020-03-16: 102/1122mm ED refractor stopped down to 90mm. Companion quite clearly recognizable as elongated brightening in diffraction ring. Relatively simple. |
|
Robert Zebahl

AB: 2020-03-16: The faint companion is immediately recognizable as a distinct, slightly elongated brightening in the diffraction ring. Easy. |
|
Robert Zebahl
Leipzig (Germany) |
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. |

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. |

AC: Stabilised binoculars, handheld. Components wide apart, almost too wide to appear as a double star. Secondary a fine speck of light beside the primary, which is >4mag brighter. According to Stelledoppie a true physical pair at a distance of 1230 light years. It is interesting to contemplate that at this distance in space the companion still looks so separate. “H“ in the catalogue name means that this double star is listed in the catalogue of W. Herschel. The 6 in the name means that it is a double star of the 6th Class [separation 1’ or larger] in Herschel’s system. |

|
Rene Merting

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). |

The components of each of the two Struves have almost the same position angles, similar separations and very similar delta-magnitudes. Struve 2470 is like an echo of 2474 but with no definite colour impression. |

Clear to wide separation. Both components of orange hue. Brighter northern component seemed to go slightly into yellow. In 10x42 also clearly split, northern component of orange hue, southern component of indeterminate colour (sky not quite dark enough at the time to see 61 Cyg naked-eye). Piazzi’s Flying Star, flying more than 5” per year to the northeast, and a true physical double with a period of 678 years. |

At 22x easy to separate with considerable difference in brightness. The primary component appeared slightly yellowish-orange, the fainter component greyish-blue. The slight color contrast was especially visible at 44x. |

Robert Zebahl
Leipzig (Germany) |
152mm (150x) |
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! |

Borderline observation with rather less good seeing. The fainter companion could be detected in the correct position angle to some extent as a small bulge in the diffraction disk. |
