NGC 884/869 - Perseus Double Cluster

Introduction | Map | Sketch | My Own Observations | References

On this page I collect my observations of the double star cluster NGC 884/869 in the constellation Perseus.

 

Introduction

The open double star cluster NGC 884/869 in Perseus is considered to be a first-rate deep sky object. Therefore, it has received a 5-star rating from Stoyan. Supposedly the double cluster should be seen with the naked eye, but I cannot confirm this. In small binoculars, however, it can already be seen well - particularly, as a double cluster.

Sketch

The sketch by Michael Vlasov (DeepSkyWatch.com) provides a rough impression of what I observed (my impression was much fainter than the sketch):
