This is the star at the top of Perseus' head. It is a wide double, easily split at 49x. The main component is a deep lemony yellow, and the much fainter companion is a nice medium blue. This pair is gorgeous, and if the secondary star was a little brighter, it would easily oust Albireo as the prettiest double in the fall sky.
