NGC 559 (Caldwell 8): A Small Flying V Cluster in Cassiopeia
NGC 559, also known as Caldwall 8, is a small, dim cluster in the constellation Cassiopeia. The cluster features 6-8 brighter stars, but at a total
NGC 7635 (Caldwell 11): The Bubble Nebula
NGC 7635, also known as Caldwell 11 and the Bubble Nebula, is a beautiful emission nebula located in the constellation Cassiopeia, which is best viewed in autumn. From my backyard, I’m able to sketch the very faint nebula as a small smudge.
NGC 7789: Caroline’s Rose
NGC 7789 is an open star cluster in the constellation of Cassiopeia. It’s also known as Caroline’s Rose or the White Rose Cluster. It’s best viewed on autumn nights. With a rather bright magnitude of 6.7, it’s hard to believe Charles Messier didn’t catalog this large and dense cluster. Thankfully, in 1783, Caroline Herschel recorded this splendid object.
Sigma Cassiopeiae: The “Smalt” Blue Jewel
Sigma Cassiopeiae is a rewarding binary star to see in the constellation of Cassiopeia. Backyard astronomers will want to use higher power to separate the pair. This is a great double star to view on fall nights.
Iota Cassiopeiae: An Unforgettable Triple
Iota Cass is a beautiful triple star system viewable on fall or winter nights.
Messier 103 (NGC 581): A Star Cluster Far Far Away
Say hello to one of the most remote open star clusters in the Messier catalog.
Eta Cassiopeiae (Achird): A Colorful Double Star in Cassiopeia
Eta Cassiopeiae, also known as Achird, is a double-star system in the constellation Cassiopeia. It’s best viewed in autumn through early winter. What’s also notable is how close Achird is to us. Relatively, this double is very close at only 19 light-years away.
NGC 663: A Cluster Known for its “Be” Stars in Cassiopeia
The cluster is notable for several reason: it has several double stars, it sits in front of a molecular cloud so most background stars are blocked, and it contains a high number of “Be” stars.
Messier 52 (NGC 7654): A Small Scorpion in Cassiopeia
M52 is a condensed cluster of mostly faint stars sitting in the Milky Way sea of stars. This makes the object tougher to find.
