If you have a telescope and you’re looking for a great double star, check out Castor, in the constellation of Gemini, the Twins. Almost any telescope and a magnification of around 100x will split this star into two brilliant white components.
Gemini is also home to Messier 35, a fine open star cluster that’s visible with binoculars close to the border with Taurus. You’ll find it just north of a curved line of three stars that mark the feet of the twin Pollux. This cluster appears large and somewhat sparse through 10×50 binoculars, and is an excellent target for almost any telescope at low power. Look out for a pale gold star with a blue companion beside it on the cluster’s northern edge.
