The Discovery Channel Telescope at Lowell Observatory, near Flagstaff, Ariz., is complete and has begun observing the cosmos with its 16-million-pixel camera. This camera is a close relative to the NSF-funded 36-million-pixel Large Monolithic Imager (LMI) that is now undergoing advanced testing and will soon be the primary imager for the DCT.
