Paper Abstract

The Magellan Baade and Clay telescopes regularly produce images of ~0.5" in natural seeing. We review efforts to improve collimation, active optics response, and telescope guiding and pointing to optimize the performance of the telescopes. Procedures have been developed to monitor and analyze image quality delivered by the imaging science instruments. Improved models have been developed to correct for flexure of the telescope and primary mirror under gravity loading. Collimation has been improved using a "two-probe" Shack-Hartman technique to measure field aberrations. Field acquisition performance has been improved by implementing an open loop model for the primary mirror control. Telescope pointing has been improved by regular monitoring and adjustments to improve acquisition times.
