Most of the time, reflectors are awkward to use for terrestrial viewing. They give views at an odd angle--often nearly upside down, or tilted sideways--and that's hard to compensate for. The details depend on just where the focuser is located on the tube (to the side, on top, or halfway between), but I've never used one for terrestrial viewing and found it easy. Maksutov-Cassegrains, Schmidt-Cassegrains, and refractors are all much better choices for terrestrial viewing. At worst, they give you a left-to-right reversed image, like looking in a mirror.
