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.
