An optical telescope is provided that includes a steering mirror configured to receive and redirect optical signals. The steering mirror is configured to be controllably oriented so as to control a direction in which the optical signals are redirected and to correspondingly control a line of sight. The optical telescope also includes a beam tube that includes a turning mirror configured to receive the optical signals from the steering mirror. The optical telescope also includes a primary mirror downstream of the turning mirror and configured to collimate the optical signals. Further, the optical telescope includes an output mirror configured to receive the optical signals from the primary mirror and to redirect the optical signals from the optical telescope. The output mirror is configured to be controllably oriented so as to control a direction in which the optical signals are redirected and to correspondingly control the line of sight.
