The star cluster known as the Pleiades, or the Seven Sisters — number 45 on Charles Messier’s list of non-cometary objects — has been a popular target for astrophotographers for many years. About 2,500 years ago, the Pleiades was considered a separate constellation. Today, it lies within the boundaries of Taurus the Bull.

Members of the Big Sky Astronomical Society from Alberta, Canada, were able to image M45 using the Canada-France-Hawaii Telescope (CFHT). The group won the opportunity to use the wide-field telescope in a contest sponsored by the National Research Council of Canada’s Herzberg Institute of Astrophysics.
