If uncorrected, the Coriolis force due to the rotation of the Earth causes
significant aberration of images produced by large liquid-mirror telescopes
. We show that this problem can be eliminated by a fixed compensating tilt
of the liquid-mirror rotation axis. The required tilt angle, which is a fun
ction of latitude and the mirror rotation rate, is on the order of 10 " for
current telescopes. This result removes the last fundamental obstacle to a
chieving diffraction-limited performance with large liquid mirrors.
