What You Should See:

This bright galaxy shows as an elongated glow with a brighter core. It is a relatively easy object, even from the latitude of Britain, despite to its low culmination. It is so bright and large (its major axis is about 23 the diameter of the Moon) that it is possible to find and identify, even in 50mm binoculars as long as you have the essential ingredient of a good southern horizon.

The globular cluster NGC 288, which lies three quarters of a field to the SE, is another easy object, showing as a dim circular glow with about half the diameter of the galaxy.
