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 |

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. |

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. |

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. |

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. |

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. |

STF519 (AB): 2020-11-07: Beautifully framed by brighter stars! Primary component A appears slightly orange with a much fainter, very close companion. To the south is S445, which forms a prominent triangle of stars of different brightness. The brightest of these three stars also appears orange. |

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. |

2021-02-24: Components A, C & D are clearly separable from each other. The fainter B component is almost completely outshone by A. The pair AB appears clearly elongated and is with concentrated observation in a few moments even visible separated. |

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. |

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. |

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. |

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. |

Suspect elongations with 8" 533x & 20" 533x, but image not good enough. But I got a nice clean split with apodizing mask, nearly perfrect disks. Orange stars well split, <1", about 1 delta mag |

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. |

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. |

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. The primary component was shining in a bright orange. |

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! |

2020-03-23: At 22x, the wide pair A-BC already appears separated, but still very tight. At 69x, A appears in a subtle orange. The pair BC shows elongated and rather greenish-bluish. At 100x BC is already visible as figure '8' and almost separated, at 129x clearly separated. Components B and C are still very close together and equally bright. The color impression remains. An interesting and rewarding triple system! |

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. |

STTA83 (AC): Wide pair, relatively bright, moderate difference in brightness. A: slightly orange; C: grey-blue. 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. All three stars form a beautiful right-angled triangle. |

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. |
