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.

February 2017

During my "winter observations", I tried to find the double cluster NGC 884/869 in Perseus. I was able to find the open clusters, but using my binoculars, I was not able to tell which of the two clusters I was viewing, or even both. The same was true for the 100P telescope. Using the GoTo mount, however, revealed that I probably saw more or less both clusters. This is one of the advantages of such a GoTo mount.

Sketch

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