Handheld. Secondary wide apart and very faint (NELM 4m9 in target area). No particular colours noted, nor with 15x45 binoculars.
With 12x36 binoculars the pair is very wide and only just still seeming to belong together. With 15x45 binoculars already too far apart for a double-star impression to arise.
Lepine 53 is a physical double at a distance to us of 178 light years on the north-western fringe of Coma Cluster Melotte 111. |

28 February 2021 at 3" separation: Very slight elongation. PA estimated at 5° (thus only 9° off, which seems fairly precise to me considering the low power of 15x and the minimal elongation, both of which make PA estimation difficult).
Intentionally flashed the eyes on the almost full Moon directly prior to observation in order to enhance acuity. Compared the sight of Porrima repeatedly with that of similarly bright Epsilon Vir (Vindemiatrix) to check whether the elongation is perhaps an artefact of the bincolulars or of my eyes, but no elongation seen there. |

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. |

Well apart but by no means falling apart, and totally dominating the 3.2° field of view. Neither component would appear particularly colourful on its own, but viewed together the primary is definitely more on the orange side and the secondary more bluish.
At 25x in 3.2° FOV and with an exit pupil around 3mm making the sky background pitch-black, STF 1694 has such a strong visual impact that it becomes a showpiece specimen of a double star. Three-star rating awarded because of this strong visual presence plus binocular accessibility (see 7x50 observation) plus true physical nature of the double (according to Stelledoppie) plus pole-star role in the Middle Ages. |

ein schicker FG-Doppelstern - ein enges Paar mit der leicht schwächeren Komponente B im Süden - schwacher Farbkontrast, der wieder mal zwischen den Sternen hin und her zu springen scheint |

2020-04-04: Lovely sight! Beautifully separated with little difference in brightness. Together with two other brighter stars the double star forms an almost right-angled triangle. At 44x the primary component appears in pale orange, the companion rather grey-bluish. |

AB: Wide compact pair. Component A (=32 Com) is brighter than component B (=33 Com) and orangish.
Nice in 8.6° FOV together with globular cluster M53, which presents as a fluffy little ball. 2° north of 32/33 Com is an interesting 2° long east-west oriented clustering of stars, and 1° north of M53 is a similar, brighter and more compact clustering. Overall an extremely attractive field. |

Using 8" 205x I see nothing. 8" 410x suspect elongation. 8" 667x I see a fleeting, bluish point just outside of first diffraction ring. A is light yellow orange and bright, 2 delta mag. to B. A star feels elongated / egg shaped. With 20" and 667x the seeing is too messy though there is a knot in the diffraction where I had noticed the point with 8". Strong feeling A is elongated. |

Wide apart. Would probably no longer feel like a pair in a crowded Milky Way field, but here, not all too far from the North Galactic Pole, the two components hold together well (and are indeed a physical pair).
Very attractive 4.5° FOV to south with east-west string of stars followed by fluffy ball of globular M53 and finally brilliant Alpha Com. |

Wide finder split, 1 delta mag, not much to recommend. Triangle of stars to the south, pointing to Bgh 46. [I did look at this at 667x to see if one of the wide pair had a pair of its own, but did not scrutinize well enough. This one should try on a really good night with 20": HDS1862 = Aa,Ab 6.56/9.69 0.4".] |

naked eye |
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. |
|
Christopher Hay

On tripod. Mizar (AB) is an uneven figure-8, the smaller circle of the 8 pointing to an estimated PA of 150°. Without knowing that this is a double star one might think the binoculars have collimation issues, but Epsilon UMa displays a perfect little Airy disk.
Alcor (C) appears bluish, Mizar creamy-white.
D seems reddish. |

70mm (10x) |
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. |
|
Robert Zebahl
Leipzig (Germany) |
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. |

White stars, well split ~6", about one delta. Surprised this was not discovered until 1901 by amateur British astronomer Edwin Holmes, who was a "seller of glass" and made his own 12-inch Newtonian. Apparently he was strongly opinionated and argued for the use of reflectors over refractors for their large aperture at low cost |

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. |

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! |

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. |

A physical double at a distance to us of 345 light years. This means that South 656 is not just close to 1 Boo AD in our perspective but also actually in space, making the two pairs one of the finest physical double-doubles in the sky for 7x binoculars. |

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 complex. A nice physical double for small binoculars. |

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. |

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 |

30 May 2021, current separation 0.65” according to Stelledoppie. No prior PA knowledge nor knowledge of relative brightnesses.
Constant elongation seen. Definite determination of position of the primary within the elongation, more definite than the relative brightnesses (consulted after observation) would have led me to expect. PA estimated at 60°.
In good moments fragments of a pear-shaped first diffraction ring surround the system, particularly on the side of the primary. An interesting and attractive sight. |

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. |
|

AB: Handheld. A strong, wide pair. Both cold white, the secondary more bluish than the primary.
Delightful in 6.3° FOV together with the "Zub's Hat" (Hay-Merting 9) asterism directly above (north of) the pair, an array of six stars looking very much like a hat or cap on Zubenelgenubi. |

Handheld, binoculars with internal stabilisation. Very wide. Component A is of a slight yellow-orange hue, its companion too weak (NELM in target area: 5m0) for colour impression.
Nice in 4.5° FOV with Mu Boo AB, which is visibly slightly wider than Delta Boo and whose component B is slightly brighter than that of Delta Boo.
Delta Boo is a physical double at a distance to us of 122 light years. |

Rather charming in 8.6° FOV with Nu1/2 Boo, which has a gorgeous colour contrast, golden-orange and ice-blue, making it one of the strongest colour-contrast pairs in the sky for binoculars and greatly accentuating the sight of Mu Boo.
In 15x45 binoculars STFA28 AB is very wide, component A bluish-white, B warmer. |

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. |

2021-08-20: The pair AB-C is easily visible already at 28x, with C being the brightest component and standing apart quite far from AB. At 86x the much closer pair AB is then also easily visible. The separation is easy, but the companion B is quite faint. Component C appeared slightly yellowish, A a bit darker. A nice triple system, which reminds me of mu Bootis. |

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 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 |

Clean split. Separation is much clearer than that of Nu1/2 Dra (STFA35), which is also in 14° FOV and is hair-fine split.

A well split and nicely compact pair. When 16/17 Dra is put at the edge of the 8.6° field of view, Nu1/2 Dra stands at the opposite edge. Their comparison thus suggests itself. 16/17 is somewhat wider than Nu1/2. While the components of Nu1/2 are of equal brightness and whiteness, those of 16/17 display a slight difference in both brightness and colour. 17 (A) first seems bluer than 16 (C), but after 20 seconds this impression flips to C and from then on goes back and forth. |

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 |

bei 32x ist ein leicht länglicher Stern sichtbar - bei 64x dann ein ganz knapp getrenntes Pärchen, A im Süden, B im Norden - beide Komponenten sind annähernd gleich hell, ein schönes enges weißes Pärchen |

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 |
