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.
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 1027: Cassiopeia’s Open Cluster Near the Heart Nebula
Cassiopeia, a notable constellation in the Milky Way, contains the open star cluster NGC 1027, located approximately 3,400 light-years away. Although it may not attract as much attention as other celestial objects, it is accessible to backyard astronomers during autumn and winter evenings. NGC 1027 features a visual magnitude of +6.8. Also known as Cr 30 and IC 1824.
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.
NGC 225: A Sailboat Sailing Through Cassiopeia
NGC 225 is an open star cluster in the constellation of Cassiopeia. It’s sometimes referred to as the Sailboat Cluster, as the stars make out a sailboat shape at wider magnifications.
