These guys near the equator have the opposite problem from us higher
latitude folks. We worry about our flip-mirrors, focusers, OAG's,
CCDs/camera bodies striking the base of the scope. They have to worry
about the dew cap hitting the base of the scope. And since the pole
stars are so near the horizon, they probably need to drift align
without being able to use the poles as an accurate starting point
due to refraction. And you thought we had it tough...
