I've had a lot of questions about this split-ring mount, so I finally
dug out my old pictures and my few remaining drawings for this webpage.
I must admit that I no longer use this mount. It was extremely stable,
but it was also somewhat awkward. It was quite uncomfortable to lean
over the mount to reach the eyepiece or the finder when the scope was
pointing near the zenith, and also when it was anywhere within 10 or
20 degrees of Polaris. It would have been great for astrophotography,
but it needed a much stronger clock drive motor.
Since I'm more of an observer than an astrophotographer, I went back
to a dobsonian mount. Someday it will have an equatorial platform
under it.
But if you want to build something like this mount, all of my photos
and drawings are shown below. I'm sorry, but I have misplaced my
schematics and firmware listings for the control electronics.
