Cassiopeia



Abbreviation: Cas
Genitive: Cassiopeiae
Right Ascension: 1.01 hours
Declination: 62.20 degrees
  Cassiopeia, the Queen, is visible in the Northern Hemisphere all year long.

Cassiopeia is known as the Celestial W when below the pole and the Celestia M when above it.

Cassiopeia is bound to her chair and forever circles the pole with her head downward. A fitting punishment by the Nereids (Sea Nymphys) for her boast of being more beautiful than all the Nereids.

Cassiopeia was the wife of Cepheus and mother of Andromeda.

Deep Sky Objects

(PAS Catalog)

M-103

 M-103 This cluster is rather small, about 8' in diameter, containing about 20 relatively bright stars, loosely concentrated. Binoculars show a slightly hazy patch.

M-52

 M-52 This is a fine open cluster. It is about 12' in diameter, and is composed of relatively bright stars reasonably concentrated to the center. It stands out well from the background, and is dominated by a bright red star. Less than a degree away is NGC 7635 (also known as the Bubble Nebula), a large, faint emission nebula.
