The descriptions
 

This Top 200 list gives you the easiest and most beautiful double stars of the night sky, quikly found in your telescope. This is not, like many other lists, an extract from a database filtering the brightest double stars. It is a summary of 200 double stars easily spotted, easily split, and mostly with different and nice colors. All 200 doubles from this list are observed by the author, equiped with a 6 inch f8 Newtonian reflector. The magnification used was never higher than 200x. All doubles are not below the declination of -12.

Double stars are pretty nice objects against the black sky for every observer. A pair of equally bright stars close to each other is very attractive. And different colors make it complete! When there are 3 or even more members, it only becomes more splendid, like the triple Struve 2816 in Cepheus. Some triples appear as a real triangle figure, like Otto Struve 147 in Auriga. And why not to spot the doubles embedded in a rich open star cluster, like Struve 485 in Camelopardalis? This list also contains a few doubles in the Pleiades, and in the Beehive or Praesepe M44.

It's very obvious, photographs never bring the astonishing spectacle, like an observer can feel thru his telescope. You only see gray disks on a photograph, while amazing colored points, not touching each other and with different brightnesses, glitter right in the middle of your ocular. The marvelous double 61 Cygni along the milky way, the first star with a measured parallax, as an example.

Keep in mind, the colors of a double star are very subjective. There are several reasons. When the secondary is much fainter than the primary, the condition of the sky, the color-sensitivity of the observer, and the aperture of the telescope. The colors of bright binaries are best seen thru binoculars. And our eyes are more yellow sensitive since we all look to a big yellow sun.

  Descriptions
 
Here are the details of the 200 preferred doubles to look for. It contains the technical information, a short description with things to know, and the most reported observed colors.
 
To make it yourself even more convenient, all doubles are rated with a number of stars:
 
*****These are the finest doubles of the night sky. Mostly the well known doubles, with beautiful colors and wide separations, perhaps containing more than 2 members.
****Very nice doubles, sometimes a little effort to split them, or standing in an attractive surrounding star field.
***These doubles are not so famous, maybe missing the brightness, but still easily found, and a great chance to see different colors.
 
A less rating does not tell the double isn't worth spotting it. It still reached the Top 200, remember!

  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.

  Maybe it is the most spotted double star. It is an extraordinary splendid and easy double with two different and marvelous colors. The source of his name is rather doubtful, but it could 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.
