Second Double - Mu Cygni
Our target on this occasion is Mu Cygni. Its stars (magnitudes 4.4 and 7.0) are separated by a generous 198" and therefore, they are an easy split in 10 x 30 stabilised binoculars. The duo is set in an attractive field Mu forming a nearly equilateral triangle with two other 5th magnitude stars lying a couple of degrees to the east.

Whilst you are there, look a half a degree north of Mu to see a slightly wider double consisting of twin 7th Magniture stars.
Although binoculars and double star observing are not often thought of together, some of the sky's best pairs are suitable binocular targets.
