Size & Magnitude
The NGC 3628 overall field of view is approx 46 x 31 arcminutes - ie ~ 1.5 x 1 Moon diameters. The image is represented at the full resolution of the ST-10XME CCD camera i.e. 1.27 arcsec/pixel

The galaxy is approx 13.1 x 3.1 arcsec in apparent size.

What it is
This is an edge-on view of a nearby spiral galaxy. It is a member of the Leo triplet group which includes the galaxies M66 and M65 . This galaxy displays a considerable amount of gas and dust that is obscuring most of the core and spiral structure. The distorted shape and an extremely faint tidal tail (not visible in this image) indicate that NGC 3628 is interacting gravitationally with the other two spiral galaxies
