Description

Processing this one was a bit of a challenge to get the right balance when adding the Ha into the RGB image without overdoing it.

The Double Cluster also known as Caldwell 14 consists of the open clusters NGC 869 and NGC 884 which are close together in the constellation Perseus. Both visible with the naked eye, NGC 869 and NGC 884 lie at a distance of 7,500 light years.
