Observing

2.3-m Historical Overview

The 2.3-m Telescope was built in the early 1980's, at the initiative of the then MSSSO Director, Don Mathewson. The entire project was managed by the Observatories' own technical staff, and a large amount of the construction was also undertaken in-house. The design of the 2.3-m, sometimes called the Advanced Technology Telescope, incorporated three radical features never before combined in a single instrument - an uncommonly thin mirror, an alt-az mount, and a rotating building.
