Astrophotographyis one of the main tools utilized by the CAS to achieve its goals. These images obtained by member Richard Edmonds are some of his best of the planets and were obtained in his own observatory in Flagstaff. They represent many hours of effort along with the excellent seeing found here in Flagstaff.
