This is the generic light duty equatorial mount supplied
with most small refractors up to 90mm and Newtonians up to
130mm. They have been around forever it seems. This particular
unit is from a Meade Model 386 90 mm refractor. This was
the predecesser of the Model 395. Unit is complete with battery
powered RA drive, aluminium tripod, slow motion controls etc.
Comes complete with rings and cradle to mount a 90mm (3.5")
O.D. optical tube. The same unit new with RA drive and no rings
goes for over $180 in the Orion Catalog. Asking only $80 for
this like new mount with Rings Cradle and Drive. However Mount
must be PICKED UP, as I don't want to go through the hassle of
packing it. I am located in the SW Chicago suburbs.
