Vaonis Vespera Pro - Cassiopeia

Introduction | DSO in Cassiopeia | DSO in Perseus | Links

On my Vespera Pro constellation pages I present objects that are located in the corresponding constellations. This page shows DSO in the constellation of Cassiopeia, plus the Perseus Double Cluster NGC 884/869, which is nearby.

Constellation pages: Orion, Taurus, Monoceros, Eridanus - Gemini, Auriga - Cassiopeia - Cygnus, Lyra, Vulpecula, Sagitta - Andromeda, Triangulum, Perseus - Cepheus - Leo, Cancer - Virgo, Coma Berenices - Ursa Major, Canes Venatici - Sagittarius, Serpens, Scorpius, Scutum, Ophiuchus

Introduction

On my Vespera Pro constellation pages I present objects that are located in the corresponding constellations. These pages are intended to help you see neighboring DSOs in context. In the case of several constellations, these lie next to each other so that the photos cover a coherent area of the sky.

This page shows DSO in the constellation of Cassiopeia (the sky "W"), plus the Perseus Double Cluster NGC 884/869, which is located nearby. More photos can be found on the DSO detail pages (click the corresponding link).

Note: Where possible, I selected photos on which several objects can be seen at the same time.
