Seeing Double – the “Wow Factor”

If you managed to find the two double stars we talked about in an earlier post, here are a couple of double stars a little more difficult to locate, but with some “wow” factor.

Among the best of all double stars and relatively easy to find is the last star of the string of bright stars that helps make the constellation of Andromeda. The second magnitude star, Gamma (γ)Andromeda (Almach), is stunning through a telescope, even a small instrument showing a superb pair separated by a good 10 seconds of arc.

Another relatively easy to find is Eta Cassiopeia, this double has a nice contrast with stars having yellow and orange colours.
