Description

Thought I'd kick of galaxy season with the Coma Cluster. At approximately 320 Mly distant, this cluster is dominated by the warm yellow glow of thousands of old ellipticals. The entire cluster is heavily influenced by the tremendous gravity of two supergiants, NGC 4874 and NGC 4889 prominent in this image. I love looking around fields like this, there's always more to find!
