Description

A nice sky region not often imaged with so many galaxies in the neighborhood when zooming in. NGC 7753 is a spiral galaxy with a small nucleus and a small bar. NGC 7752 is its companion that seems attached to one of NGC 7753's spiral arms. It was first thought to be an elliptical galaxy, but recent images show that it is an irregular and disrupted system with three major H-{alpha} areas. The pair seem to have recently collided and are very similar to the famous M-51 galaxy pair.
