ein einfacher Doppelstern - Komponente C steht mit gutem Abstand südöstlich von A - Komponente A ist gleißend weiß, C wirkt dagegen richtiggehend grau-braun |
|
Christopher Hay
Seeheim (Germany) |

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! |

bei 32x mein erster Eindruck ist, dass zwei annähernd gleichhelle sehr eng stehende Sterne mich wie zwei Augen anschauen, das unmittelbare Sternumfeld passt schön und verleiht dem Doppel eine hervorgehobene Stellung - Komponente B im Westen ist nur minimal schwächer als A - in guten Momenten ist die Trennung sehr eindeutig erkennbar |
|

bei 64x zwei helle, knapp getrennte Sterne - die schwächere westliche Komponente zeigt ein schönes, helles Gelb und wirkt dadurch leicht schwächer - zurück auf 32x ist eine 8 mit deutlicher Einschnürung erkennbar - der Farbunterschied ist ebenfalls deutlich |

Beautiful view. Easy to separate with components of the same brightness. It is noticeable that there are no brighter stars in the immediate vicinity, so that the double star stands out very well. |

AE: bei 32x auf der entgegengesetzten Seite im SW zeigt sich Komponente E in gleichem Abstand und mit gleicher Lichtschwäche - die beiden schwachen Komponenten D und E haben A voll in der Flügelzange - das Ganze funktioniert auch bei 20x, aber das sind die beiden schwachen Komponenten nahe der Sichtbarkeitsgrenze |

STT351 (AC): Orange stars, noticeable magnitude difference ~0.5, separated just less than ~1". 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. |

Very challenging. AB is obvious, A a bright light orange, B is blue and faint -- with careful examination I do get a scintillating small balls separated ~1" and near equal -- averted vision brightens these to pinpoints but I can't hold that resolution direct. Stelle Doppie says first measure of this pair is in 1901, so it's not a Struve discovery, likely Aitken or Hussey with the Lick 36-inch |

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). |

AC: I had strong visual color response, though the disks were somewhat bloated with seeing: A was blue-white, B was yellow-white, and C red-orange. Colors were the same at 100x but the disks smaller. With an 8-inch mask at 205x, the disks were tight and overall everything was fainter. C was less red, more grey, and much fainter, so the color was not so strong and maybe would not be described as orange |

V595 Lyr. Very tough! In unsettled seeing it is an elongation or lopsided at all powers. However at best moments it tightens enough to show a very subtle notch & also different brightness and color, A being light orange-yellow, and ~1 delta mag B a deeper orange. Discovered in 1902 at 0.2, it has only a 14.64 year period, it will make a rapid circuit to the other side by 2026 (though only 0.1"), and "widen" to 0.2" again by 2030. Should be fun to observe! |

bei 32x ist A schwach und orange, B südlich ist gut getrennt erkennbar, noch schwächer und farblich nur noch als "dunkel" zu bezeichnen, dadurch aber ein auffälliger Farbkontrast -runter auf 20x kann ich B leider nicht orten - der Doppelstern bildet mit einigen 7-9 mag hellen Sternen nördlich ein markantes Muster wie ein Angelhaken (oder einer Häkelnadel, wenn man bedenkt, wie eng der Bogen südlich geschwungen ist) - STF2442 bildet dabei die Spitze der Rundung des Hakens - sehenswert innerhalb dieses Musters |

bei 57x zeigt sich B genau nördlich von A wie so eine kleine Bommel - ein sehr ungeliches Paar, ich schätze 3 Größenklassen Helligkeitsunterschied (2.32 mag lt. Stelle Doppie) - A strahlt weiß und B … naja … was bleibt der schwachen komponente anderes übrig, als grau zu schimmern |

Widely split. Attractive together in 0.8-degree FOV with Struve 2455AB a little less than half a degree south. The secondaries of the two doubles point towards each other, a nice sort of double-double. According to Stelledoppie 2457 is a physical double, while 2455AB is not. In 2457 the brightness of both components is less than those of 2455AB, their separation greater, and their colour contrast (itself hard to define) is greater. In 2455AB focussing on the A-component precisely is hard to achieve, perhaps due to an unresolved field star very close to it? |

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. |

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. |

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). |

AB-C: Secondary nicely set off as a fine pinprick beside the much brighter primary. Secondary seems ice blue at first sight, but that impression fades the longer I look. Primary essentially colourless. Secondary not seen in 3-inch at 30x. Physical double according to Stelledoppie. |
|
Christopher Hay
Seeheim (Germany) |
150mm (300x) |
AB: Used a moment of unusually good seeing in July 2019 to find out whether anything can be done with the 6-inch on this super-tight pair. No prior PA knowledge. At 200x nothing happening. At 240x a northwest-southeast elongation. At 300x distinctly stretched. According to Stelledoppie a physical pair with a very short period of 23 years. Distance a little over 0.2“ from 2010 to 2020, shrinking to 0.03“ in 2026, reaching 0.2“ again around 2040. This is one of very few double stars whose complete orbit can be observed several times over in a human lifetime, be it only as a periodical elongation/contraction. The observability of the elongation in just 6 inches of aperture is aided greatly by the almost equal brightnesses of the components. |

Wide split. No colour impression. Reminiscent of view of BLL48 in 15x45 binoculars, see observation.
Not a visually exciting pair, but I visited it intentionally because it is a physical pair which is the source of excitation of the Wolf-Rayet nebula WR 135. Together with WR 137 (aka BLL48, see entry in this listing) and the more well-known WR 134, BLL46 (aka WR 135) is one of the first three objects of its kind to be discovered in 1867.
BLL46 is also listed as the variable star V1042 Cyg, its distance to us is approximately 5000 light years.
All three WR objects can be viewed together in a FOV of just 1.5°. Together they form an arc, concave to the northwest, that is also known as "the Wolf-Rayet Cascade". |

Very wide split. B-component just bright enough to hold it steadily in these binoculars under NELM5 sky.
Would not have felt the pair to be double without prior knowledge. But I visited it very intentionally because it is a physical pair whose A-component is the source of excitation of the Wolf-Rayet nebula WR 137. See also observation of BLL46, another Wolf-Rayet double star.
Is also listed as the variable star V1679 Cyg, its distance to us is approximately 7000 light years. |

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. |

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! |

The AB-C pair is easy at 205x, C is a faint star ~4" separated from bright A (8.41/11.97 4.0"). AB is much more difficult. At 1067x it is mostly overlapping disks & I can tell its orientation. But at repeated best moments, I get an instant of the finest hairline split with noticeable magnitude difference & I can estimate an orientation relative to nearby stars. It's PA [246°] is nearly perpendicular to AB-C [131°] -- this is how I confirmed I have it. Cocteau discovered it in 1968 with the Nice 30-inch refractor at 0.2". 42.46 year period, last observation in 2005, with grade 3 orbit (which is certain but not definitive). It is currently coming off apastron with the current orbital solution at 0.167" separation. It will tighten very rapidly the next few years, but even on the opposite side of it's orbit it will not be detectable by me, I need to wait until 2050 to try again -- but since the PA will be similar I won't notice that change. I can only look forward to the tightening and maybe detectability again. If is the 0.167" is correct I have exceeded the Raleigh, Dawes, and Sparrow criteria and it's a new personal best -- and given I did not split some similar pairs later in the night, I was very lucky with the seeing at the time of the observation |

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 |

With apodising mask to suppress bright white A's brightness, and with foveal coaxing due to its very faintness, B emerges into view ~3", a very small fine point. Likely tougher than it should have been due to the sky haze -- indeed after seeing it as above, when I went back down to 333x I could see B direct vision, knowing where and what to look for. Discovered with the Lick 36-inch in 1890 at 2.94" |

Burnham discovered at 0.7" in his 6-inch in August 1873, and when compiling his catalog in 1899 noted it had made substantially one revolution. This will widen through this decade and should be resolvable in a few years, getting back to ~0.7" in 2030 |

An obvious pair, I wonder why Struve did not note it. Wide, ~6", ~1 delta mag. A is light orange and B a slightly deeper orange. Lies in a dense arrow shaped asterism. Hans Schjellerup was a 19th century Danish astronomer who was something of a polymath, who compiled a list of red stars, and studied Chinese and other languages in order to study old astronomic records |

A star is orange and bright, the mask is giving a good clean image at moments, with some disturbance (seeing 6/10). B star is faint but a nice hard point outside A's first diffraction, ~2", noticed it right away even though it is on the edge of direct vision, but do not need averted to see it. Dependent on seeing. Tried at full 20" aperture but A was too messy, and did not clean up well enough with apodizing mask. Low in the sky and in fact lost it behind a tree a few minutes after making the observation" |

Current separation 0.155". 314 year period, it will only make modest position angle change in my time. Burnham discovered in 1888 with the Lick 36-inch at 0.3"! It seems Hough also discovered it in 1888 but published his results later, HO 282 |

Suspected at 205x, better view at 333x. Very fine split, faint pair, nearly 1 delta mag. Burnham: "The principal pair was discovered with the 15.5-inch of the Washburn Observatory, and it was then stated that C might also be double. This was verified with the 36-inch in 1888, thus making a pretty but difficult quadruple group." Unfortunately I didn't bother with the AC pair since it was widely separated, so I missed observing CD 11.28/12.30 1.4" (1.2" when suspected at Washburn & later verified at Lick). Amazing |

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. |
