On this page I collect my observations of the open star cluster M 34 (NGC 1039) in the constellation Perseus.

Introduction

The open star cluster M 34 is located in the constellation Perseus to the West of the bright star Mirfak. According to Karkoschka and Stoyan, it is primarily an object for binoculars, but they also recommend to look at the cluster's center with a small telescope (that is, at low magnification).

M 34 (NGC 1039)
Size: 35' (Stoyan) - a little more than the size of the moon
Distance: 1,600 Light years (Stoyan)
Rating: *** (Stoyan)
