Description

A clear (though not particularly dark night) calls for a distant target, and the Deerlick Galaxy group was in a good spot to start the night. NGC7331 is fairly close at a distance of 40 million light years, but the smaller surrounding galaxies and most of Stephan's Quintet at top right are 300-365 million light years away.
