By tilting a Dob arrangement with the correct angle, it would be possible to make an equatorial out of it. There are some problems associated with this, particularly lateral load on the vertical (if tilted, the polar) axis, a problem which would be less serious at higher latitudes. At the north pole any Dob (except the Portaball) would work as a perfect equatorial.
Advantages would be easier navigation for manual/visual use, and benefits for persons considering astrophotography. And the "difficult zone" would be moved from zenith to the less interesting polar region.
Has anybody made or considered to make such an arrangement with a Dob? Any problems? (I do not think about older fork mounted Newtonians - there were a few of those, very heavy and expensive telescopes.)
