Explore the constellation Cassiopeia
Cassiopeia offers numerous celestial sights including stars, nebulae, and clusters.

The constellation Cassiopeia is widely recognized for its distinct W-shaped asterism formed by its five brightest stars. Located in the Northern Hemisphere, it is best observed in autumn and winter. Among its notable features are stars such as Alpha and Beta Cassiopeiae as well as deep-sky objects like the Bubble Nebula and clusters like M52.
The Bubble Nebula, designated NGC 7635, is part of Sir Patrick Moore's Caldwell list and is a favored target among astroimagers. Open clusters such as M52 and NGC 7789 display an array of stars across varying magnitudes, offering captivating views through telescopes of different sizes. To observe the irregular galaxy IC 10 and NGC 147, a satellite of the Andromeda Galaxy, larger telescopes with nebula filters are recommended.
Double stars like Sigma Cassiopeiae and open clusters such as the Owl Cluster and M103 are amongst the highlights for telescope enthusiasts. The Heart and Soul Nebulae, named IC 1805 and Westerhout 5 respectively, can also be observed with appropriate equipment. Each of these objects contributes to Cassiopeia's reputation as a celestial treasure trove for astronomers and observers.
