Description

Melotte 111 is a relatively small but nearby open cluster, consisting of about 40 stars, easily seen with the naked eye in the constellation Coma Berenices. In terms of angular size, it is the largest open cluster in our skies. At 280 light years distance, it is roughly twice as far as the Hyades, the next largest angular size open cluster in our skies. It is superposed upon a rich background of distant stars and far more distant galaxies.

This image is composed of four LRGB panels taken with the Takahashi CCA250. Several nights were required to capture the data because the weather was stubbornly uncooperative!
