I've been working on a new EQ mount based on the old Horseshoe design. So far it has gone together better than I thought, although I still have the optics to complete.
Eventually it will be used to do short duration Astrophotography.
It started when I was given an old 10"dob tube a few years back. I have a 10' dob in my backyard but it doesn't get as much use as I'd like.
I drew the plans to make a new mount and using the mirrors, etc, build a new scope while keeping the original intact.
The mount is built from plywood of various thicknesses. The motor drive is from Jaycar with a few extra bits from an old photocopier plus a harmonic wheel for the final drive.

A truss-tube will be built for the optics then some fine tuning with copious amount of Earl Grey tea.
