The Collinder catalogue is a catalogue of 471 open clusters compiled by Swedish astronomer Per Collinder. It was published in 1931 as an appendix to Collinder's paper On structural properties of open galactic clusters and their spatial distribution.[1]
Cr 334 and 335 are duplicate listings of the same object.
The original alias given for Cr 339 is the galaxy NGC 6393. The correct alias for Cr 339 is the open cluster NGC 6396.
The original alias given for Cr 371 is of the nebula which surrounds an open cluster he discovered. He apparently did not know he was first to make the distinction.
Cr 374 is embedded within the much larger Messier 24.
Collinder erroneously believed that Messier 11 was a globular cluster.
Collinder’s description of Messier 73 is actually for Messier 72, a globular cluster, and not the object he intended for, Cr. 426.
