Abstract
An unobscured afocal three-mirror telescope can provide a two-axis gimbal architecture that is more compact, more lightweight, and less expensive than traditional coudé path approaches. The telescope can create a real exit pupil and position the exit pupil on a 90-degree fold mirror. Two orthogonal rotational axes can intersect substantially at or about the center of the telescope's exit pupil and on or about the center of the last fold mirror.
