Hi Steve,
In my beginners opinion, an equatorially mounted scope is much more difficult to use than a Dob. I'm dreaming of the day I can afford a 8" - 10" Dob.
The instruction manual that came with my Orion 130mm (which was a gift) says that once it is polar aligned, the scope should be moved ONLY on the R.A. and Dec. axes.
I've uploaded the relevant pages from the manual, I hope they are readable.
Hope this helps.
P.S. Bear in mind that the instructions are for the northern hemisphere, so the north and south instructions should be reversed, I think.
