I explore how far off-axis one can use a liquid-mirror telescope. Borrowing the optical setup of adaptive optics, I assume that the wavefront corrections are applied on an image of the pupil of the telescope. While not necessarily the best design, this lends itself to an analytical treatment that shows that the severe aberrations of a paraboloid used at large angles from its optical axis can be corrected over thin (several arcseconds) circular strips of sky to surprisingly large zenith distances (as high as 45 deg). This would be useful for astronomical observations that do not require a large field of view (e.g. spectroscopy of single objects or very high resolution imagery).
