This paper builds upon past work demonstrating the integrated performance of a programmable diffractive element of large pixel count with a telescope system. More specifically, a liquid-crystal-based spatial light modulator is used as a reconfigurable diffractive optical element in a telescope system to extend the systems field of regard by compensating large aberrations associated with off-axis orientation of the primary mirror and by steering object light over angles greater than the instantaneous field of view.
