Collinder 69 is the large and loose cluster around this double star Lambda Ori.
It's located at the top of the Orion figure. Together with the two Phi stars, it forms the head of the Hunter.
The double itself is the last one in a line of three stars. Two white stars, maybe yellowish, can be glimpsed fairly close.
The companion is slightly fainter. |

This stunning multiple star lies right at the center of the Orion Nebula M42. It's
the middle star of the Sword of the Hunter.
Its name, the Trapezium, is not stolen. Four gems twinkle in an attractive tiny area, recent products in the gas
and dust cloud. Lots of faint stars in the
surrounding area also are physically involved, all of them are highly young and unstable lights,
less than 100 000 years old.
The Trapezium was first sketched in 1656, and first photographed in 1880. Also try to spot the other doubles in
this region, like Theta 2, Iota and Struve 747.

Xi Uma is the double at the very bottom of the Ursa Major constellation, that is
rather north of Leo, forming with Nu Uma two conspicuous stars. It is a very close orange pair of two bright stars.
The companion is slightly fainter. The two suns orbit each other in only 60 years, while the separation moves from
1.6 to 3.0 arcseconds. In 1828, it was the first calculated orbit for a visual pair, seen in 1780. |

The famous Alcor and Mizar, the naked eye double star. Mizar itself is
a gorgeous pair of two equal white stars. In the 13th century it was already a naked eye test. And it was a test to
become an archer for Karel V. The name Mizar comes from a 'belt', and Alcor from a 'black horse'. In an ancient myth,
Alcor was the lost seventh lady of the Pleiades, staying with her lover. Mizar is the first seen binary, the first
photographed binary, and the first spectroscopic binary. Also the third star in the same field has a name, Sidus
Lodoviciana. |

Don't worry about the low declination of the Scorpion, because the constellation
borders officially track a small region north of the Antares area, and this pair lies just in it. The primary
itself is a yellow pair, but too close. The fainter third component
is bluish and fairly far from it. Directly at its south lies the other fine double Struve 1999. |

Maybe it is the most spotted double star. It is an extraordinary splendid

mean 'of the rainbow'. The double was first seen in the 17th century. After 5 million years, the brightest star
of the heaven will be ... Albireo. |
