Cassiopeia is a constellation in the Northern Hemisphere. In this article I hope to cover some of the interesting objects that can be found in this region of space.

The constellation is recognisable from the fact it has a W shape. Cassiopeia can be found near to Perseus and Andromeda.

For the purpose of this article I will be using the K-stars package.

Principle Stars These appear in Kstars. I have set the software to display objects fainter than Magnitude (m) 5.0.

• Caph (2.3m)
• Schedar (2.3m)
• Navi (2.2m)
• Ruchbah (2.7m)
• Segib (3.3m)

$\eta$ Cassiopeiae (3.5m) $\zeta$ Cassiopeiae (3.7m) $\kappa$ Cassiopeiae (4.2m) $\theta$ Cassiopeiae (4.3m) $\nu$ Cassiopeiae (1) (3.5m) $\nu$ Cassiopeiae (2) (4.7m) $\iota$ Cassiopeiae (4.6m) $\omega$ Cassiopeiae (4.9m) $\psi$ Cassiopeiae (4.8m) $\pi$ Cassiopeiae (5.0m) $\xi$ Cassiopeiae (4.8m) $\lambda$ Cassiopeiae (4.7m) $\rho$ Cassiopeiae (4.6m) $\sigma$ Cassiopeiae (5.0m) $\varphi$ Cassiopeiae (5.1m) $\chi$ Cassiopeiae (4.8m) $\mu$ Cassiopeiae (5.2m)

Data from Kstars application.

The constellation also has many objects such as open clusters.

The Owl Cluster (NGC 457) is close to the star $\varphi$ Cassiopeiae.

There are no galaxies within the constellation but star $\zeta$ Cassiopeiae (3.7m) appears to be the closest to the Andromeda Galaxy (M31).

You can see the milkyway behind the constellation. This could explain the number of open clusters in the region. However this is more speculation as I am not an expert on this.
