On this page I collect my observations of the galactic emission nebula NGC 7635 (Bubble Nebula) in the constellation Cassiopeia.

Introduction

The galactic emission nebula NGC 7635 (Bubble Nebula) in the constellation Cassiopeia is located close to the well-known open star cluster M 52 and looks like a bubble. With the Vespera, it can be observed together with M 52. A Vespera Pro mosaic can also include NGC 7538 and C9 (Cave Nebula).
