M31, taken with mobile equipment from at a star party in eastern UK.

The site, whilst reasonably dark, is quite exposed and on a hillside just a mile from the sea, and is nearly always windy. The seeing and transparency was variable, so I used a One Shot Colour camera to try and get useful pictures in as little time as possible. The Skywatcher Esprit 150ED very nicely resolves tiny details and far distant star clusters.
