They don't require frequent collimation, and often for casual observers
don't
require any out of the box, although you SHOULD check for this once you
get your scope. But once they're collimated they stay that was pretty well.

I think that they are a good beginner's scope; easy to maintain, give good
views. Be aware that you need to protect these scopes from the daytime heat
as they take sometimes an hour or more to cool down, and until they do, the
seeing is not good through them (thermal currents in the tube caused by the
heated optics).

Good Luck !
