Messier 52 (M 52)

Introduction | Map | My Own Photos | My Own Observations | References

On this page I collect my observations of the open star cluster M 52 (NGC 7654) in the constallation Cassiopeia.

 

Introduction

According to Stoyan, the open star cluster M 52 in the constellation Cassiopeia belongs to the richest open star clusters of the northern sky. Karkoschka, on the other hand, characterized it as "many weak stars in the telescope." For me, it was hard to find at the beginning, and there was not much to see (see Karkoschka) - next time, it got better...

With the Vespera, it can be observed together with NGC 7635 (Bubble Nebula). A Vespera Pro mosaic can also include NGC 7538 and C9 (Cave Nebula).
