I have been warned by a friend that some telescopes will only function in
the Northern hemisphere.

In general is it true that scopes are made to function in either Northern
or Southern but not both hemispheres?

This is due to the following 2 factors:

(1)The tilt of the wedge requires an equatorial rotation in opposite directions
for the 2 hemispheres.

(2)Power supplies in South Africa, Australia and new Zealand are 50 cycles and
not 60. Which could be a problem even when a voltage transformer from 220v/115v is used.

Please comment on these 2 points.
