Mine has the same logic. At 35cm and F/4.6 I can view the zenith without a ladder, even when the scope is mounted on a tracking platform. In fact, given that you're rarely viewing right at the zenith, you can get away with a slightly bigger scope (say 40cm F/4.5) and very rarely have to use a step stool.
