Hi Luis,
a first advice I should give is to use the tripod as low as possible (by
shortening its legs to the maximum that is possible): it will add some
stability to the mount.
By the way, forget about 750x because the maximum (tolerable) power for a
telescope is 2.5x per millimeter (ie 65x per inch) and the maximum power I
use on my 4.5" is 180x.
clear skies, Yann.
