T4 Automated Photometric Telescope

(T4 APT)
(automated 75-cm telescope to a long-term star monitoring survey)

The T4 Automated Photometric Telescope (T4 APT) is an automated 75-cm telescope dedicated to photometric observation of a set of around 75 somewhat-Sun-like stars, varying from F-type star to K-type star. It is located at Fairborn Observatory, an observatory of a number of automated telescopes. T4 was inaugurated in 1993 at a time when Fairborn Observatory was on Mount Hopkins, Arizona, but the observatory and its telescopes were later relocated tory to a remote southern Arizona site near Washington Camp. As far as I know, T4 carried out this project from its inauguration, and continues to do so.
