Prof. Brian Cox' TV programmes have stimulated a lot of interest in Stargazing. A Facebook friend is showing a photograph of the Plaeides taken with a Canon 1000D and a 200mm telephoto lense. The technique seems to be to take a set of 1.5min exposures and stack them presumably using Photoshop. He used 33 digital photographs to get a bright image. Registering them and dropping them onto a single base layer must be quite tricky. A fascinating and ingenious procedure for a digital camers enthusiast though.
