Double cluster in perseus is one of the most spectacular objects in the sky - easily visible with a naked eye even under moderate conditions (at it's combined magnitude of 4.3m). This is an excellent targer both for binoculars and a telescope. The clusters NGC 869 and NNGC 884 feature dozens of bright, densly packed stars. Also several prominent yellowish stars are scattered around the field of view.
