This is a pretty and easy double star in Cancer, in the north of the constellation. Although not as bright as Albireo, nor quite as contrasted, there are similarities as the primary (mag 4.0) is yellow, the secondary (mag 6.5) bluish and the separation 30". They have a common proper motion though no orbit has been found.

North is up, west is right in this image
