Glen, I see what you are saying. I'm just not sure what's better - more moisture on the tube when parked horizontally, or moisture travelling down the outside of the tube and accumulating along the edge of the mirror cell, where it joins the tube. I suppose the best solution is to just cover it when not in use.
Re mount, I recall the OP contemplating a GSO in another thread. The fact that other, more expensice dobs have the same problem only shows that GSO dobs are damn good value.
