There seems to be a lot of confusion about the names of these objects. IC 1284 usually refers to the red cloud, also known as Sh 2-37. Some people refer to this cloud as IC 1283, others indicate that IC 1283 refers to a smaller sub-cloud inside IC 1284. The overall red cloud may also be referred to as IC 4700.

The lower blue reflection nebula is variously known as NGC 6590, NGC 6595 or NGC 6589. The other small blue nebula is known as NGC 6589 (seems more correct).

The star cluster at the upper left is M 24.
