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. |

V547 Cas. Faint, very fine pair, seen at 205x and had a better look at 333x. Wide, ~4" slightly reddish faint stars. SkyTools brought this up as a short period pair, however it won't make a significant change in my time. It turns out A is also a pair, MCY 1 Aa-Ab, 10.8/12.5 0.5" with a period of only 15.59 years -- discovered by one D.W. McCarthy (no relation!) in 1989 during the first results of the Steward Observatory Infrared Speckle Camera using their 2.3 meter telescope. The Ab star has a mass of only 0.18 of the sun. I think it is gettable visually with the Challenger on a good transparent night, or with the Lick Great Refractor if I ever have the good fortune to observe with it |

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.

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. |

The group of stars strikes the eye while sweeping from Mirach to Tau/Upsilon TRI. First thought I'd found an open cluster. Two pairs with practically opposite PAs. Southern pair AB much closer than northern CD, but brightnesses within the pairs very similar. A nice double-double. |
|
Robert Zebahl

152mm (22x) |
The components A-D and F easily visible as a rather conspicuous group with comparatively large distances. I didn't pay attention to the component E. No brighter stars in the immediate vicinity. The pair AB and CD are very similar; CD a bit wider with opposite position angle. Very nice multiple star also for smaller telescopes. |

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. |

AB: Elongated at 667x, with 1067x it is a clear elongation with the B star sticking out like a stump, but not notched. It is now near periastron, and will widen rapidly to 0.448" by 2030. 184.9 year period. Need to go back and make a sketch, since it will be on the opposite side of the A star in 2030 |

In brief moments definitely split with a hair's breadth of black in-between. The rest of the time tantalisingly close to popping apart. Brightness difference distinct enough at all times to identify the southern star as the A component. Both components pure white.\A physical pair 164 light years distant from us. Also known in ancient times as the "First Star in Aries", as it was closest then to the vernal equinoctial point on the ecliptic |

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
Fremont (California/USA) |
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! |

|
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. |

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). |

CHR6 (Aa-Ab): This is a component of Iota Cas, STF 262 (which is a really pretty triple). 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 |

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. |

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 |

Component of STF 366. Faint, and is mostly a hazy elongation which brightens each end with seeing --- difficult on such a night as this with poor seeing and transparency. It makes me wonder how Struve missed it? There are 26 observations in WDS so it should have been determined to be physical by now |

Well separated but very strongly appearing to belong together. This impression is fostered by the almost identical brightnesses and the complete lack of visual competition in 0.6° FOV. Leading star appears at first sight more orange than the other, but after a while this shifts to the other star. The pair is visually very attractive at this power, and a true physical one at 670 light years distance from us. |

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.

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!

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. |

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. |

STF747 (AB): Clearly split, with very distinct magnitude difference between A and B components. Hand tremor prevents detection of colour contrast, if there is one at all. A very pleasing tip to Orion’s Sword.
A true physical pair according to Stelledoppie. Distance to us of 1610 light years could indicate membership of stellar association Orion OB1 and thus physical relationship to Orion nebula complex. |

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. |

eine echte Herausforderung - Komponente B taucht mit etwas Konzentration ganz schwach östlich von A auf, der Abstand ist ordentlich - B ist schätzungsweise 1.5 bis 2 Größenklassen schwächer - Komponente A strahlt schneeweiß, B wirkt wegen des Helligkeitsunterschiedes grau |

Just split. A little difficult. Suprisingly more difficult than STF572 about 15° to the northwest, although the numbers are very similar and the two systems are standing at identical elevation above horizon. At 40x STF742 is no longer definitely split, but M1 half a degree to the west is strong in 2° FOV by way of compensation. |

B-C fine split, C appears slightly weaker than B. Component A is too far away at this power from BC to feel that it belongs. Very attractive ensemble overall in the same field of view with Sigma Ori, which also presents three of its components. |

76mm (40x) |
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. |

Binoculars with internal stabilisation, handheld.
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. |

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. |

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. |

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.

mit etwas Konzentration sind beide Sterne getrennt zu erkennen - A und B sind halb so weit voneinander entfernt wie das nahe liegende Pärchen STTA74 - Komponente B im SW ist genauso schwach wie B bei STTA74, aber dadurch, dass er näher zum Hauptstern steht, ist er schwächer sichtbar |

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 |

A slight difference in brightness is noticeable. At 129x, the view is magnificent. The two bright components A & B present themselves yellowish, the fainter component C rather greyish. STF 948 can be well observed in a field of view with the neighbouring double star STF 946. Both show a nice overall scenery. |

bis 107x vergrößert, aber mehr als eine kleine kaum wahrnehmbare Ausbeulung nach Norden war nicht drin - höher Vergrößern wegen schlechtem Seeing nicht ratsam in der Nacht - kurios, der Stern strahlte zweifarbig, bläulich im Norden und ein helloranger Rand im Süden - ob das ein Dispersionseffekt war oder hervorgerufen aufgrund der beiden eng stehenden Sterne, vermag ich nicht zu sagen |

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. |

Southeast of the pair in a much larger distance there is another, fainter star, which appears orange, partly reddish. It does not belong to the system.

BC: On tripod. B is set off well from visually distracting A (which in turn is the primary of HJ3945, the Winter Albireo). C seen clearly and well framed in 6.3° field of view with Tau CMa at centre of field.
Shaya 508 BC is a physical double at a distance to us of 303 light years. Reported in E.J. Shaya, R. Olling, 2011: Very Wide Binaries and Other Comoving Stellar Companions: A Bayesian Analysis of the Hipparcos Catalogue. The C component is more than 3° to the south of the B component.

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 |
