NGC 772 is a fascinating galaxy that is also known as Arp 78. Because it is very close to and gravitationally interacting with NGC 770 (the elliptical galaxy immediately below NGC 772), the spiral arms and shape of NGC 772 are distorted. Additonally, this field has a great many smaller galaxies. In the original TIFF image, I can identify 15 objects which are obviously galaxies and many dozens of faint galaxies scattered throught the image. As an example, close inspection of this photo will reveal a collection of about 13 very small galaxies just above the main galaxy (they look like small spots above NGC 772).

In this image, North is Up. This image is cropped to 58% of the original full frame.

Notes	This image was a lot of fun to process, as trying to bring out the faint galaxies and the extended regions of the galaxy was a bit challenging. This is an object that is not commonly photographed, so I'm pleased that my image came out as well as it did.
