M31 - Andromeda galaxy

 

This spiral galaxy probably looks similar to our own Milky Way if it were possible to see that from 2.5 million light years away. Bands of interstellar dust are quite clearly visible. Two small companion galaxies (of dwarf elliptical type) can also be seen in this photo: M32 is the more compact one on the upper left (it looks like a bright star); M110 is the more obviously galaxy-like one on the lower right.

The core of the galaxy. It is too large to fit completely into the field of view of the telescope. The telescope was on an HEQ5 mount, driven but not guided.
