AB: Clearly split. A definitely brighter than B. Under a NELM 5m5 sky both components appear weak in these mini-binoculars and no colour impression arises.;
WZ Cas is the variable designation of component A of STTA254. This semiregular carbon star has a mean brightness range of 6m8 to 7m7, and can reach extreme values of 6m3 at one end and 8m8 at the other. Perhaps it was too deep in a minimum at the time of observation to show colour with 1 inch of aperture? 15x45 binoculars revealed colour in this night, see observation below. |

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 |

Fine split. A is mandarine orange. BC has trouble displaying its colour due to the overpowering light of A, but in good moments is clearly blue.
A-BC is a physical double at a distance to us of 393 light years.
BC is also physical, with a relatively short period of 63 years for C to circle B and a very tight periastron. Unobservable in 2013 at periastron with 0.1". Since then the angular separation has been widening rapidly and will reach 0.4" in 2029. B-C will then become observable in large amateur telescopes for three decades, after which C will fall quickly back to B. |

BC: Component of STF 205, of which A is a brilliant orange and BC bright blue. In BC I can only see elongation through the speckle at 667x and 1067x. Short 62.63 year period which will get "easier" to about 0.2" by 2045 |
|
Mark McCarthy

508mm (1067x) |
BC: I spent a good long while on this one, and tried hard to nail down the position angle. At 1067x, both with and without an apodising mask, but both times with a #80A light blue filter, which did seem to calm the diffraction a little, I had a clear view of the elongation with a strong sense of the weaker end being to the East or to the ESE. I also tried a 78% central obstruction mask, and while the diffraction became a grid, and the disks much smaller, I could clearly see the same elongation and weaker end, though at a much smaller scale. To my delight the current orbital solution puts the PA at 120.6-degrees, 0.179" separation, so I think I have detected it. I can't wait until 2033 when this becomes an easy pair! |

Wide split. A is cream-white, B of indeterminate colour. Attractive pair in 1.7° FOV, scenery accentuated by 63 Psc about 3/4° to northwest.
While pleasant with 30x80, the pair becomes suprisingly difficult to split with 20x80, presumably due to the cumulative effect of 2m delta-mag and the red colour of the companion, which makes it stand out less than if it were blue (colour not seen, but stressed by Uwe Pilz in his 105mm observation, see below). |

CHR 6 at 1067x and seeing through the speckle image, I get elongation with a suspected blunter end which I assume is the B side, PA to the north [it's actually to the south -- my general orientation is correct but mis-interpret the brighter end]. Physical with 47 year period, currently at periastron and will tighten to 0.2" by 2036 |

At 27x split, but still tight with noticeable difference in brightness. A slight difference in colors could be seen. At 56x the color difference was very evident: The brighter component appeared slightly yellowish, the fainter one slightly bluish. Highly recommended! The sketch was done few days later during another observation. |

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. |

13x: CD definitely split, A uncertain, B not present.
18x: A, C and D definite, B uncertain.
32x: A, B, C and D present and clear.
Mediocre seeing but good transparency with strong M42 and an inkling of M43 at 32x. B is an eclipsing variable with a period of 6.5 days and an amplitude of 0.6mag, presumably obervation was at minimum, which would explain the difficulty in seeing it at lowest powers. C is the main source of excitation of the great Orion Nebula M42/43. |

C clearly set off from AB. AB is yellow, no particular colour seen on C.
AB (also known as BU 1240) is a physical double at 566 light years distance to us. So is AB-C according to Stelledoppie, making this a physical triple system. |

Wide split. Yellow-blue collour contrast of AB to C. Neither of the two colours very strong on its own, but in fine contrast to the other. Reminiscent of the way Polaris appears in a 3-inch at 40x, with less delta-mag, making it easier, but lacking Polaris' dramatic blue of the companion. |

10x42 |
Binoculars with internal stabilisation, handheld.
AB-D: No split, nor any elongation of AB towards D seen.
AB-E: E is set off well from AB but harder to split than the numbers would suggest. This is partly due to the major delta-mag, and partly to the circumstance that D effectively reduces the "free" stretch of sky to 29".
STF761 is a nice complement a few minutes of arc to the west and makes the visual impression of possibly belonging to the Sigma Ori complex, but Stelledoppie doesn't confirm this. |

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.

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! |

2020-04-15: At 31x all three components are visible, with B still very close to component A. Component C is rather dim overall. At 57x, A appears white-yellowish, B slightly orange. |

AB: bei 45x ist B ganz dicht nördlich an A angrenzend erkennbar (knapp getrennt), B etwas heller als C im Süden - bei 72x wird die Trennung einfacher und alle drei Sterne stehen fast auf einer Linie
AC: bei 45x ist C ganz schwach südlich von A erkennbar - bei 72x schätze ich, etwas mehr als die doppelte Entfernung AB, C wirkt grau, während A und B weiß strahlen |

Observation from the city at half moon. At magnifications between 187x and 280x I could see the very dim companion almost permanently near the first diffraction ring. But the diffraction ring itself was hardly visible. Main problem here was probably the low brightness of the companion. |

Hair-fine, but definite and constantly held split. Charming in 3.3° FOV with Phi1 and Chi Cnc.
Easier than I would have thought at only 25x. This is clearly aided by the very well-matched brightnesses of the components. The 70% full moon nearby in Leo also helps, as its brightness boosts the eyes' acuity. During the observation I gaze intentionally directly into the moon at intervals in order to utilise this effect, a technique honed in earlier binocular observations of planets.
Primary is slightly brighter than the secondary, again surprising considering that delta-mag is only 0m05 (6m16 to 6m21 according to Stelledoppie). Not a physical pair, alas, although it looks so much like one. |

At 25x a wide split, substantial difference in brightness, B a fine pinprick of light. B appears light blue at first, but colour impression disappears quickly - an interesting visual effect repeated several times. According to Stelledoppie a true physical pair. Nice together with Struve 1350 in same FOV. A very fine double-double for very small apertures. |

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. |

Handheld. Wide, striking matched pair. Nice together with triangle of 27/28/30 LMi, and thus also easy to find. HJL1057 also in field to southwest.
Delicate colour contrast in the triangle makes this a very attractive field: 30 LMi is yellowish-white, 28 reddish-white, 27 LMi colder.
In 15x45 binoculars STTA104 becomes almost too wide to feel it is a double, but the colour contrasts in the triangle become clearer. |

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. |

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. |

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. |

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

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! |

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. |

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. |

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. |

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 |

STFA28 (AB): Handheld. Wide split. A compact uneven pair. Component A is bluish-white.
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. |

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. |

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. |

16 Dra seems more bluish than 17 Dra, the latter seems slightly yellow in comparison and is distinctly elongated. At 84x 17 Dra is cleanly split and such a delightful view together with 16 Dra that I had no desire to ramp up the magnification. All three stars belong to a physical system. |

ein einfacher Doppelstern - Komponente C steht mit gutem Abstand südöstlich von A - Komponente A ist gleißend weiß, C wirkt dagegen richtiggehend grau-braun |

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. |

auf den ersten Blick bin ich enttäuscht, weil ich nur einen hell strahlenden Stern erkennen kann - dann aber mit etwas Konzentration ist südöstlich von der Leuchtgranate ein ganz schwacher Begleiter zu erkennen - ein sehr ungleiches Paar mit geschätzt 4 Größenklassen Unterschied - Komponente C wirkt rotbraun und steht ordentlich getrennt von A |

Very far apart, almost so far as to appear to not belong together. However, in the 3° field of view 70 Ophiuchi, which is also a physical double, is seen to be also split. Thus a very attractive field overall.
67 Oph and 70 Oph are the left and right nostrils of the bull in the old constellation Taurus Poniatowski (Poniatowski’s Bull). 68 Oph (the tip of the bull’s nose) and 73 Oph (the bull’s right eye) are also double stars, but can’t be split at 25x. All four doubles – 67, 68, 70 and 73 Oph – are physical, a rare assemblage! |

What's curious is the AB pair is HU 66 AB listed as 7.90/8.40 0.1" currently, with HU 66 BC as 8.40/8.25 0.9". So my question is, if AC is physical, and if BC are physical too, why is AC uncertain? It would seem they should all be sharing orbits? Perhaps it just cries out for additional measures -- AB is grade 4 and BC is grade 5, so they are confident of physicality but there's not enough data to nail it down. |

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). |

SHJ282 (AC): A is very distant from C but the two are still a fine pair. Colour of C is more striking than that of A, in a manner similar to my simultaneous observation with 60mm at 15x, but not quite as pronounced.
C has a companion set off from it by a hair of black. I estimate PA from C at approx. 80°, separation very roughly 2". Surprisingly can't find this companion in the double star catalogues. |

2021-08-20: At 28x the much fainter C component is clearly visible at quite a large separation. The tight pair AB showed up at 160x and 187x clearly elongated, partially as an '8'. A small difference in brightness could be guessed. Higher magnifications did not yield any gain. The air was only moderately steady (seeing 3/5). |

bei 18x ein ausgesprochen schickes Sternpaar - B zeigt sich nördlich von A gut getrennt, aber trotzdem noch eng seinem Partner stehend - Helligkeitsunterschied eine Dreiviertel Größenklasse - sonst gibt es kaum vergleichbare Sterne im Umfeld, so dass sich das Sternpaar schön prominent präsentieren kann |

Primary ruddy red, secondary wide apart but too faint for any colour impression. Straw-yellow Epsilon Saggitae half a degree to the west with its ice-blue eastern companion enhances the experience of colour contrast in the FOV and is actually more attractive than HN 84 with this aperture and power. |

Christopher Hay
Seeheim (Germany) |
150mm (96x) |
Main component ruddy tangerine orange, companion wide apart and ice blue. The longer I look the stronger the colour contrast becomes, which is by no means normal in many doubles. Epsilon Saggitae in same 0.8-degree field of view is straw-yellow with a cold blue companion (a field star?) pointing away from Epsilon in the direction of HN 84. I can’t think offhand of a better colour-contrast pair that can be framed in this manner in the same FOV. |

2021-07-24: At 30x the components A, B & C are easily visible, whereby A & B are still quite close together. The bright component A appears in a pale yellow. At 92x also the pair FG is separated easily and looks less belonging to the system because of the wide separation to the other components. All in all it is worth observing. |

2019-08-22: While the primary component appears quite unspectacular in a white, the companion U Cygni is much more interesting. It is a carbon star whose brightness varies between 5m9 and 12m1 with a period of about 463 days. It appears in mostly intensely orange, and even deep red in the towards its minimum. Extremely rewarding! |

DA1 (BC): This is part of STF 2690 A-BC, which is a white, wide, near equal, pair (7.12/7.39 17.7") observed with 8-inch at 205x. I suspected BC at 8-inch 333x, & had overlapping disks with 8-inch 533x. With 20-inch 533x I see a hairline split, slight magnitude difference. Seeing is not supporting it well, but it's clear. Very nice. Dawes discovered in 1840 at 0.7" -- probably with his 8-inch Cooke refractor -- so at current 0.369" it's not surprising I only had overlapping disks at 8-inch. It's a physical pair, with a 236.52 year period, and will widen another 0.1" in the next 15 years |

On tripod. Clearly split, northern component A substantially brighter than B. Both orange, whereby A is distinctly more yellowish than B (sky quality similar to that of earlier 15x45 and 10x42 observations). Also seems to be split using the 8x42 handheld, but hand tremor makes this uncertain. |

Christopher Hay
Seeheim (Germany) |
15x45 |
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. |

V447 Cep ! Excellent pair, seen at small scale at this magnification. Nice clean split, half delta mag, really pretty. A is variable 7.26 - 7.62 V over a period of 7.52655 days, but there is a lack of recent observations on AAVSO. If it were near maximum it might be more difficult to resolve the split at small aperture. I also pick up a very faint white star the averted vision, widely separated -- this is AC, 7.99/11.91 29.2. FYM 192 AD, mag 12.98, not seen |

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! |

Neatly split, whereby the first difraction rings of each component touch the Airy discs of the other. Component A in the north seems marginally more yellowish than component B in the south.
Zeta Aqr is called Sadaltager, meaning „Merchant’s Luck“. It is framed nicely by Pi, Gamma and Eta Aquarii, with which it forms a striking triangular asterism known as „The Tent“. Moreover, Zeta Aqr is a true physical double. This constellation and the beautiful telescopic appearance warrant a two-star rating. |

AC: Hand tremor hampers splitting A and C at this low magnification, as the apparent separation is small. Nonetheless, a grey-blue C dances next to the luminous-orange A.
Component A is the prototype of the Cepheid class of variable stars, with a brightness variation of a full magnitude over 5 days. To assess a somewhat difficult handheld binocular split like this it would really be necessary to know the momentary brightness of A, but I didn’t have a telescope at hand. |
