The motion of Mars that makes it necessary to occasionally re-center it
in the eyepiece these days is due to the difference between the Earth's
and Mars' orbital motion. It's in retrograde motion now and appears to
be moving to the west. IOW, it's orbital motion, not the Earth's
rotation. Same with the Moon and Sun.

This has nothing to do with the OP's problem, though, unless there is
something new going on with the planets!
