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. |

Strongly supplemented to the south in 4° field of view by Psi2, Psi3 and Chi. Field relatively empty to the north, which gives the field further tension. According to Stelledoppie a true physical double 275 light years distant. |

Despite the wide separation the pair holds together visually very strongly, and dominates the FOV. And indeed, Stelledoppie states it is a true physical pair at 174 light years from us. Component A is ice-blue. I probably wouldn't have any strong colour impression coming across component B on its own, but standing next to A it seems a washed-out orange. |

On tripod. Wide split. A orange-red, B a tiny pinprick of light. Attractive sight in 7.3° field of view, with Zeta Psc neatly on western edge of FOV.
Physical double according to Stelledoppie.
Three-star rating awarded because this is a physical double that can be resolved at 7x, while dominating the field of view with more power and presenting a strong colour contrast with more aperture (see 20x80 observation below). As an added bonus, S398 is just half a degree south of the ecliptic and is thus visited regularly by planets and the moon. |

|
Christopher Hay
Seeheim (Germany) |
15x45 |
Binoculars with internal stabilisation, handheld. C far distant from A. Due to this distance and the major delta-mag the two stars do not present the appearance of a double, C looks rather like a field star.
Yet in fact the two are a true physical double at a distance to us of 289 light years. |
|
Christopher Hay
Seeheim (Germany) |
71mm (13x) |
A-C wide split, C a fine little point of light.
Visually un-exciting as such, the attraction of this pair resides partly in contemplating that it is a true physical double. Furthermore, in this small refractor 14 Arietis AC can be observed together with another physical double in the 5.5° FOV, namely Lambda Arietis (listed here as H5 12). |
|
Christopher Hay
Seeheim (Germany) |
180mm (113x) |
Components A, B and C from a wide grouping. B is very faint, somewhere around 11m to 12m, in contrast to the 8m0 stated by Stelledoppie. Observed on 12 February 2021. Is B variable? DSS sky survey shows the same delta-mags that I saw, so it rather appears that Stelledoppie has a mistake in its database.
A is creamy white, C grey, B too faint for any definite colour impression.
According to Stelledoppie a physical triple system at a distance to us of 289 light years. |

AB: der Doppelstern steht innerhalb einer sehenswerten Formation aus 6 Sternen, die ein gleichseitiges Dreieck bilden - die hellsten drei Sterne bilde eine Seite im Norden, zur Spitze nach Süden werden die Sterne immer schwächer - STF270 steht mitten in der Nordseite - Komponente B ist wie ein kleiner zarter Hauch nordwestlich von A erkennbar, Helligkeitsunterschied mehr als 2.5 Größenklassen - kein reizvoller Fernglas-Doppelstern, aber die Umgebung ist interessant |

Well split. Main star yellow-orange, secondary an ice-blue pinprick. With overall brightness of 5m1 just visible to naked eye under my suburban sky. Interesting star field with a line of 5 stars pointing S-SW away from 15 Tri and a further striking star chain to the west. Placing Gamma-Delta-7 Tri within 7.5° FOV makes a very attractive overall field. Mira variable R Tri just ½ degree to the S-SE was around maximum at time of observation and presented a much paler orange than 15 Tri A. Charming colour contrast ensemble with the two components of the double plus the variable. |

ein extrem komfortabel getrenntes Sternpaar - Komponente A im Süden strahlt weißgelb, B ist 1.5 Größenklassen schwächer und wirkt kupfergrau - interessant: parallel zu den beiden Sternen stehen westlich zwei deutlich schwächere Sterne in gleichem Abstand und Positionswinkel wie die Komponenten von 15 Tri - alle 4 Sterne bilden ein Parallelogramm |

STF307 (AB): Miram, die Komponente A ist satt gelb und bildet ein flaches Dreieck mit zwei Sternen westlich und nordwestlich, die aber 1,8' und 3,9' entfernt stehen - dazwischen wird alles vom Glanz von Miram überstrahlt - im Fernglas hat B mit den eigentlich ordentlichen Daten wie Abstand 30,4" und Helligkeit 8.5 mag (andere Quellen sagen 10.7 mag) trotzdem keine Chance auf Erleuchtung |

On tripod. Well separated. A evidently brighter than B. A appears to tend towards orange, B rather towards blue.
Most of the Alpha-Persei cluster can be viewed together with S430 in 7.2° FOV. Seen thus, S430 feels likes a distant little echo of the powerfully orange-blue pair Sigma Per in the cluster.
South 430 is a physical double at a distance to us of 498 light years. |

Theta Tauri. Luminous orange and blue. Wide apart but very much feeling to belong together, despite the many stars of the Hyades all around.
A physical pair. The data suggest separation with naked eye is possible, something to try in good health under a steady sky. At all events with naked eye Theta Tauri is at the centre of the southern stroke of the Hyades' distinctive "V" shape. In the binoculars, by ignoring Aldebaran, which is not a cluster member but a foreground star, it suddenly becomes apparent that Theta Tauri is in fact at the centre of the Hyades in our sky and is its lucida. This impression is supported very nicely by 7x and 8.6° FOV. Definitely one of the finest doubles for this class of binocular. |

AB: On tripod. AB distinctly separate, very double-star-ish. Slightly wider separation than STF 747 AB two degrees to the south. Embedded in glow of M42. Theta 1 Ori (Trapezium) A/C/D appears slightly box-like without resolution.
Theta2 Ori is a physical double at a distance to us of 1546 light years. |

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. |

AB-D: No split acheived. However, focussing on AB feels uncertain, presumably due to disturbance by D. Also not split with 15x60 on tripod.

On tripod. Clearly separated. Large delta-mag plus scintillation of primary prevent colour perception of B. The 6x30 binoculars show the colour better in the same night. Interesting to note that the 7x45 is at a disadvantage in this regard while the 10x56, however, is superior. |

On tripod. Widely separated. Rather charming. B distinctly blue. Scintillation plus atmospheric dispersion of A (15° above horizon) prevent determination of any particular hue of A.
A physical double at a distance to us of only 29 light years, which means Gamma Leporis is in our immediate galactic neighbourhood. |

AB: When idly viewing NGC 2169, the “37 Cluster” or “IC37”, I noticed that the brightest star in the 37, namely the one at the NW corner of the 3, is a nicely split double with a thin slice of darkness between the components. PA matches the top bar of the figure-3 well. Stelledoppie lists components of STF848 from A to K, but notes that all are either not physical or uncertain. To my eye only the A-B pair appears double-like. |

AD: Wide separation, small difference in brightness. Slight difference in color, but difficult to describe. Component A at least seemed rather white. South of STF1007 there is also the double star HJ3288 and the star HD52976, which appears in a bright orange. Together in one field of view a beautiful sight. |

Handheld. Widely split matched pair. Easy to find half a degree south of 45 Gem. Comfortably viewed in 8.6° FOV together with STTA 80 AB and STF 1007, all three systems well-to-wide split, a charming trio of doubles. Alternatively, ENG 28 can also be viewed together with Zeta Gem (Mekbuda) 5° to the north.
Engelmann 28 is a physical double at a distance to us of 152 light years.
There is an interesting quirk about the ENG designation, on which Stelledoppie notes: Some time after publication of the IDS, the designation for Engelmann was changed from EN to ENG and that for Engelhardt from ENG to ENH. This has led to considerable confusion between the two. |

AE: Component E is a fine pinprick of light. The distance to A is so substantial that the pair would not normally be felt to be a double. This makes it all the more interesting to contemplate that this is a true physical double in our galactic neighbourhood at 59 light years distance to us. ALC = Allen, C., published in 2000. |

AB: On tripod. B immediately pops out from the glare of A, thanks to its substantial distance. B is a vivid blue.
Emboldened by the unexpected ease with which the pair can be seen in the 10x56, I launch an attempt with 7x50 bins on the tripod. This is thwarted by the many rays emanating from A in the image. Too much exit pupil?
AB is a physical double at a distance to us of only 79 light years. |

Handheld. Wide split but secondary very faint (NELM 5m1 in target area). STTA104 one degree to the northeast has practically identical separation yet is much stronger.
The charm of this pair resides less in its visual appearance than in contemplating that it is a physical double at a distance to us of 287 light years. |

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. |

AC: Handheld. Components A and C, making up Shaya 224, are well framed in 6.3° FOV. Component A is cold blue.
Component C (= HIP 55262) is about three-and-a-half degrees south-southwest of component A (= 81 Leo) and is close to the Leo Triplet of galaxies. Two galaxies of the Triplet present themselves (sky quality: NELM 5m0 in target area), M66 is an elongated little nebula with its main axis pointing roughly towards C, while M65 is a faint but definite nebular presence with direct vision, closer to C than M66 is.
Shaya 224 is a physical double at a distance to us of 143 light years. |

15x45 |
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. |

Christopher Hay
Seeheim (Germany) |
25x80 |
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. |

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).

This one should try on a really good night with 20": HDS1862 = Aa,Ab 6.56/9.69 0.4".] |

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: 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. |

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. |

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. |

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! |

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). |

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. |

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. |

Self-built binoculars, hence the unusual specification. Made of top-quality teleconverters, apochromatic and sharp to the edge.
With naked eye under good suburban sky 16 Cyg is just seen. In the 3x binoculars the double is split into two finest points of light in good moments despite the low magnification. A physical pair according to Stelledoppie.
Two-star rating awarded because this is a true physical pair that can be split with the smallest binoculars and reveals increasingly more with growing binocular size (brightness disctinction between A and B in 7x50, colour distinction in 15x45). |

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). Western, weaker component Alpha 1 Cap well separated from Alpha 2 Cap in good moments. Much more difficult to split naked-eye than Mizar/Alcor (Zeta UMa). Not a physical double. |

2020-08-19: Gorgeous sight, separated with distinct brightness difference. Primary component appeared rather white with a greyish companion. With two similarly bright stars to the east and southeast STF 2687 forms a prominent triangle surrounded by several star chains. About 12 arcminutes apart to the southeast of STF 2687 is another pair of stars, which is particularly striking because of its color (bluish & orange). |

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 |

Stabilised binoculars, handheld. A very elongated figure-8 very close to popping apart. According to Stelledoppie a physical double with a period of 3249 years. Observed in June 2019 when separation was 8,89“. Will be 8.67“ in 2030 according to Stelledoppie. |

Very tight pair but clearly split with black in-between. Observed in July 2019 when separation was 8,89“. An excellent object to test the resolution of large binoculars. Struve 2725 a few arcminutes to the southwest is a further good test object for magnifications >20x. |

bei 32x knapp getrennt - Komponente A ist schön gelb, B im Westen ist gut 1.5 Magnituden schwächer (lt. Stelle Doppie Helligkeitsunterschied nur 0.67 mag) - zusammen mit dem wesentlich schwächeren STF2525 gut 15' südlich sehenswert |

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. |

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. |

2020-08-19: The double star is located in a rather poor environment and is therefore very conspicuous. Clearly visible brightness difference with rather small separation. The primary component appeared white-bluish and thus quite cool, while the companion showed a warm hue (yellowish/orange?). |

AB: 2020-08-19: Very nicely separated, slight difference in brightness. No color was visible. Towards northwest is pi 1 Cygni, which is surrounded by several medium bright and fainter stars and together with STF 2832 presents a very attractive view. The region southeast of STF 2832 looks rather poor. |

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. |
