Paper Abstract

This paper outlines progress to-date with the commissioning of the Bent-Gregorian focus at the Large Binocular Telescope. Active alignment at this focus utilizes and auto-guider system and a Shack Hartman wavefront sensor to determine system perturbations and drive corrections into various active optical components. Reported results include the correction of bi-nodal astigmatism, performance of the Shack-Hartman wavefront sensor, convergence of wavefront correction, convergence time, as well as various results pertaining to tracking and guiding.
