I'm looking to pick up an older LX200 to use as a DIMM (differential image motion monitor) setup. What is needed is an lx200 in alt-az mode; don't need wedge, tripod, etc. Just the drive base/fork and scope. The scope can be in any condition; the DIMM function simply requires a reasonably large aperture (8" or larger) for accurate measrement of seeing conditions.

I want to spend as little as possible on this, so an old LX200 with bad coatings, a beat up tube, etc. is perfect our needs.

The reason that an LX200 is required is that the observatory is remote, and we need to let the scope run 24 hours a day, and the LX200 in alt-az mode will simply trace out a small circle near Polaris, and thus avoid any wire wrapping problems. Wedge and Equatorial mounts would have serious wire wrapping problems with this approach. The DIMM monitor needs to be as low-maintenance as possible.
