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. |

Component A appears at first to be more orange than component B, but after about ten seconds the orange impression flips to component B, and from there on goes back and forth. Visited Psi1 Psc several times, taking breaks of a few minutes in-between, and each time the same effect occurred, with A initially appearing to be on the orange side. |

AB: Psi1 Psc is well separated. Very strong visual presence in this instrument. Components almost identically bright, colourless. 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. |

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

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! |

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). |

B well set off from A. Glare from A is an issue, consciously trying to ignore A helps. Very slight yellowish tone of A. Seeing the difficulty makes it clear why attempts in other nights to split the pair with 25x80 binoculars failed. |

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 |

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 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. |

5 Nov. 2022. In good transparency I notice while casually looking naked-eye at the Hyades that Theta1/2 Tau seem elongated. Looking now with direct concentration, the pair moves clearly apart. Theta2 is visibly slightly brighter than Theta1, PA estimated at 350°. Following this up directly by looking at Mizar/Alcor in Uma, that pair, which I can always split naked-eye reasonably well if transparency allows, now seems super-wide compared to Theta1/2 Tau. I estimate the separation of Mizar/Alcor as being two-and-a-half times that of Theta1/2 Tau. |

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. |

BU1047 (BC): Component of STF 645. Awesome flex on Struve. Near equal BC stars suspected at 533x, hairline split at 667x. A really fine little blue pair near bright white A. Physical with a 32.1-year period, it is at apastron now and will get impossibly close in the 2030s, becoming visually detectible again in the later part of that decade. Burnham discovered in 1889 with the Lick 36-inch, and recorded 0.4" separation |

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. |

AB: zusammen mit STF745, 747 und 754 im GF, ein wahres Doppelsterngewimmel! STF752 ist der wohl schönste Doppelstern von allen vieren, die strahlende Komponente A im Norden spielt klar die Hauptrolle, die deutlichst schwächere Komponente B schmiegt sich trotz eindeutiger Trennung regelrecht an ihren Partner an |

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. |

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.

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. |

STT134 (AB): im nördlichen Teil des wunderschönen Sternhaufens M 35 strahlen auf den ersten Blick zwei komplementär gefärbte Sternpünktchen auf - ein leuchtend orangefarbener und südlich darunter ein meist bläulich strahlender, zeitweise verliert er seine Farbe und wirkt eher grau |

2022-02-27: At 30x the uneven pair AB appears widely separated. A shines in a glaring bright orange, B in the south appears slightly bluish. Then at 92x component D is also very faintly visible. All three components form an acute-angled, nearly isosceles triangle. Also at this magnification A appears bright orange, B gray-bluish. At 171x D still remains pretty faint. |

At 49x the pair AC is beautifully separated with a significant difference in brightness. At 100x, the close pair AB is also separated, although still very close together. 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. |

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. |

AB: 13 May 2022 (5.5" angular distance according to database). Moon four-fifths full a few degrees north of Spica in Virgo. 70mm binoculars stopped down to 42mm aperture. Directly after looking the Moon I was able to split Castor AB definitely. Could hold this for a full minute, only then did the split start to become uncertain. Repeated the observation several times, found the split to be definite each time. |
|
Christopher Hay
Seeheim (Germany) |
32x70 |
AB: 13 March 2022 (5.5" angular distance according to database): Moon only 6° away and two-thirds full in the middle of Gemini. After concentrated observation of the Moon I slewed quickly to Castor to exploit the heightened acuity provided by viewing the bright Moon. Castor clearly split with fine black between A and B. After a while the split became more difficult but could still be held. Followed this up with the same eyepiece previously used in the achromatic 70/400 binoculars now placed in 71/400 fluorite apochromatic telescope, thus again yielding 32x. Again A and B split after observation of the Moon, but harder to hold with the mono apochromat than with the bino achromat. |
|
Christopher Hay
Seeheim (Germany) |
36mm (33x) |
AB: 16 April 2022 (5.5" angular distance according to database): With Käsemann (KSM) polarising filter at 33x two kissing Airy disks which seem to move apart in good moments, but this is uncertain. Without filter at 33x just a squat figure-8 far removed from separation. With polarising filter at 40x definite separation, fine first diffraction ring of component A. Without filter a stretched figure-8 with no separation. At 50x clear and stable separation with and without filter. Best view at 66x, a ghostly pair in pitch-black FOV, the first diffraction rings of A and B merging, that of B very faint. With a Baader Neodymium filter the positive effects are similar to those of the KSM polarising filter, but the clarity of separation is not quite as great as with the polarising filter. |

63mm (26x) |
AB: Experiment to determine the smallest magnification to separate Castor. I observed on 2022-05-09, 2022-05-11 & 2022-05-18. At 26x and 30x easily seen as a double star, but not clearly separable due to outshining. At 70x of course easily separated. Stopped down to 30mm aperture, Castor appeared partially separated at 26x, but very barely. The right viewing position at the eyepiece was important. At 30x with 30mm aperture, Castor was cleanly separated, but extremely tight. Following a hint from Christopher Hay, I also used a red filter from Baader to avoid outshining at full aperture. Now also a separation at 26x was possible, whereby the components were extremely close to each other. For me a magnification of 26x seems to be the minimum to separate Castor cleanly, if the brightness of the components is reduced sufficiently. |

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 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!

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 in reclining chair, binoculars with internal stabilisation. 14 May 2022 (4.7" angular distance according to database): Pear-shaped. Strong orange-lemon yellow, a fruity affair. PA estimated 140° without prior knowledge, a good enough match, considering the low magnification, to the database figure of 127° ascertained post-observation. |

21 May 2022 (4.7" angular distance according to database): Hairfine split, slightly difficult due to bloated stars in these achromatic (not apochromatic) binoculars. Both components orange, with secondary going into yellow. Thin cloud moving through tightens up the star images and makes the split much clearer. Clearest shortly before clouds become so dense as to swallow the pair. |

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.

Smart 75 AB (also known as Shaya (SHY) 216) is a physical double at a distance to us of 121 light years.

A wide pair but still appearing visually to belong together. Component A is a creamy gold-white. Component C is pale blue, but the colour impression fades after looking for a while. In parallel observation with 3-inch at 32x and 7-inch at 67x I see no particular colour of C, an interesting difference to observation with one-and-a-half-inch.

A is a very light orange, and when seeing stills and the diffraction rings are steady, B appears as the tiniest fleck, well outside the first ring about 3", a deeper duller orange color. Physical. Burnham discovered with the 18.5-inch Washburn refractor at 1.8" -- his extra aperture helped as mine is wider but with just a 7-inch, and explains why Struve never saw it. He wrote: "It is obvious from the measures that this belongs also to the small star, and they must form a physical system." |
|
Mark McCarthy
Fremont (California/USA) |
317mm (553x) |
Bright light orange star. As seeing resolves it to a disk and eliminates the diffraction, a tiny, faint star appears, planet-like, (~3") from the star. Only at the best moments, visibility of B star helped by averted vision. |

|
Mark McCarthy
Fremont (California/USA) |
762mm (457x) |
The pair split immediately at 457x. A little diffraction but no doubt a small blue point just outside the first ring. Using the 8-inch aperture mask (effectively 8-inch f/18!) had a nice star image of A but B disappeared -- it became an averted vision, threshold object. Barlow here was no help to show it better. I think Ho 50B is fainter than the current data, and if the older data say it should be fainter, then it may well be variable. However, later in the night, I estimated Ho 50B to be as bright as STF 1964D, which is 9.02 |

Elongated at 533x, but the sky is too hazy, and this pair is a bright star's glare. BU 1283 looks like a piece of debris from an exploding bright star. [Theta Leo, 3.33v, to the SW] |

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. |

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. |

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. |

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. |

Already clearly split in 3x opera glass. In 15x45 the pair becomes interesting due to clear colour contrast, 17 CVn orangish, 15 CVn much colder, almost bluish.

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). Very attractive 4.5° FOV to south with east-west string of stars followed by fluffy ball of globular M53 and finally brilliant Alpha Com. |

Wide finder split, 1 delta mag, not much to recommend. Triangle of stars to the south, pointing to Bgh 46. [I did look at this at 667x to see if one of the wide pair had a pair of its own, but did not scrutinize well enough. This one should try on a really good night with 20": HDS1862 = Aa,Ab 6.56/9.69 0.4".] |
|
Mark McCarthy

178mm (205x) |
Super-wide pair even in the finder, and I am very surprised to see it is listed as physical, at least as proper motion is concerned. The close pair HDS1862Aa-Ab I thought I saw but it is too fleeting, seeing not supporting higher magnification. Reviewing the Gaia DR3 data, which includes parallax, it confirms there is overlap in the weighted distance but the weighted separation of the pair is 19,121 AU, which means this is very likely not a physical pair |

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. |

At a position angle of roughly 265° I had the feeling something was going on; a kind of protusion of the primary, coming and going. 200x: yes, now a stellar condensation kept popping in and out of sight at the same position, just on the outside of the first ring, which itself was coming and going in not-so-perfect seeing. Upping the magnification to 240x and 300x didn't improve the view. |

AB: With handheld 7x42 binoculars I cannot separate B from A. With handheld 10x42 binoculars with internal stabilisation, B emerges in fleeting moments from the glare of A, wide. Yellow-orange hue of A that I had already noticed with 7x42 binoculars becomes clearer with 10x42. With stabilised 20x60 binoculars I can hold B constantly, but B is far more difficult than component C (AC = Shaya 633) despite B and C having practically identical brightnesses.
AC: With handheld 7x42 binoculars component C is clear and very wide from A. A seems yellow-orange. Not visually exciting, it is nonetheless pleasurable to contemplate that this is in fact a physical pair travelling together in space, 317 light years distant from us.
SHY = E.J. Shaya, R. Olling, 2011: Very Wide Binaries and Other Comoving Stellar Companions: A Bayesian Analysis of the Hipparcos Catalogue. Component A is HIP 67250, C is 67041. AB is also physical, hence ABC is a triple system. |

On tripod. Well split. A compact pair directly next to orangish-yellow 6 Boo in a remarkably attractive 7.3° FOV together with widely separated 1 Boo (STF 1772 AD) two degrees southwest plus Eta and Tau Boo about three degrees south. A physical double at a distance to us of 345 light years. This means that South 656 is not just close to 1 Boo AD in our perspective but also actually in space, making the two pairs one of the finest physical double-doubles in the sky for 7x binoculars. |

STF1835 (A-BC): bei 32x erscheint der Stern leicht unrund, verschmiert - bei 107x präsentiert sich BC gut getrennt im Süden von A - Helligkeitsunterschied eine Größenklasse (1.75 mag laut Stelle Doppie) - bei 64x sind beide Sterne auch getrennt erkennbar, BC strahlt warmweiß |

Handheld, binoculars with internal stabilisation. A tight pair, indirect vision helps to see black in-between. Eastern component clearly brighter. Nice in 4.5° FOV with Rho and Sigma Boo. A physical double at a distance to us of 1140 light years. |

180mm (200x) |
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. |

AB: Zeta Boo. Short period. First impression was moderately well notched overlapping disks (eg. not barely notched, but not strongly notched either). 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 |

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. |
