Liquid Mirror Telescopes (LMTs) are based on a large objective mirror formed by spinning a reflective liquid around the zenith. LMTs offer numerous advantages but are limited to observations along the zenith only. We present a solution which expands their field of view around the zenith by effectively compensating for the large off-axis aberrations inherent to the LMTs. The rotating liquid mirror is augmented with an adaptive optics system based on a magnetic liquid deformable mirror (DM) which cancels out the large off-axis aberrations. We present the simulation results of a prototype setup comprising a 30 cm rotating liquid mirror used as the primary mirror. The large off -axis aberrations at 25o from the zenith are corrected by a convex secondary mirror and a magnetic liquid DM controlled by an array of dual-layer electromagnetic actuators. We demonstrate the feasibility of expanding the application of the LMTs while retaining their cost-effectiveness as an advantage over conventional telescopes.
