Paper Abstract

Lowell Observatory's Discovery Channel Telescope is a 4.3m telescope designed and constructed for optical and near infrared astronomical observation. It is equipped with a cube capable of carrying five instruments and the wave front sensing and guider systems at the f/6.1 RC focus. We report on the overall operations methods for the facility, including coordination of day and night activities, and then cover pointing, and unguided and guided tracking performance of the mount. We also discuss the implementation and performance of the open loop model for, and manual wavefront sensing and correction with the active optics system. We conclude with a report on the early integrated image quality and science performance of the facility using the first science instrument, the Large Monolithic Imager.
