Description

A bonus clear night. The seeing wasn't great though, at least the half moon set around11.30pm.

This is a lovely galaxy and worth having a look at if you've a larger scope.

NGC 772 is around the same size as our own Milky Way but it lies 130 mly's distant. It is interacting with the nearby lenticular galaxy NGC 770. The star count in this image was 63 (highest) but there are a host of galaxies present.
