NGC 7331

On this page I collect my observations of the spiral galaxy NGC 7331 in the constellation Pegasus.

Introduction

The spiral galaxy NGC 7331 in the constellation Pegasus is according to Stoyan only visible in telescopes. It is seen nearly edge-on. Close to it, there are the galaxy NGC 7335 and two even smaller ones (NGC 7337 and NGC 7340). A little farther away, but still close to it, there is Stephan's Quintet (NGC 7317).

Size: 4' x 1.5' (Stoyan)
Distance: 60 millions light years (Stoyan)
Rating: * (Stoyan)
