The Double Cluster consists of two open clusters, NGC869 and NGC884 located in Perseus. Estimated age is 12.8 million years.
Although visible to the naked eye, they need optical aid to show the two individual clusters and to see them in all their glory.

NGC6885 and NGC6882 are a pair of overlapping open clusters located in Vulpecula. NGC 6885 is the small group of brighter stars, and NGC 6882 is the set of fainter stars or possibly it is Collinder 416 as there is some confusion from William Herschel observations. Age is estimated at 1.4 billion years.

- Right Ascension: 17h 40.1m
- Declination: −32° 13′
- Distance: 1,600 ly
An open cluster located Scorpius. The name derives from Robert Burnham's description that it resembles an outline of a butterfly with open wings. The cluster is estimated to contain up to 300 members, and its age is 50 to 100 million years old. Like most open clusters, the stars will disperse over millions of years and become more background stars in Scorpius.
