Does the Advanced VX mount (#91519) use bearings in the Dec axis?
March 27, 2013
The Advanced VX mount uses a bearing surface that the Dec axis slides on, but it does not use roller or ball bearings. Roller bearings are not needed on the Dec axis, as the mount only tracks on RA and the bearing surface is plenty for the DEC motor when autoguiding is in use.
