No definite elongation of AB seen at 110x, seeing is poor. But nice pinprick of light wide off to NE, seems bluish, this is the C component.
AB-C is physical at 429 light years distance from us, and so is A-B, so this is a physical triple system. Very easy to find 3° due west of the Pleiades. |

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. |

At 28x the pair AC is nicely separated without any problems. The close pair AB is already recognizable at 86x as a clear figure '8', at 125x wonderfully separated. The components A & B appear yellowish. Very nice view together with STF 946 in one field of view! |

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. |

Engelmann 37ABCD is a physical group at a distance to us of 608 light years.
Stelledoppie notes about the ENG designation: 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. |

Rather charming in 8.6° FOV with Nu1/2 Boo, which has a gorgeous colour contrast, golden-orange and ice-blue, making it one of the strongest colour-contrast pairs in the sky for binoculars and greatly accentuating the sight of Mu Boo.

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. |
