Increased Loading Capacity
Both the RA and DEC Axes are made of sturdy steel with brass wheel gears. This enables the mount to carry loads of up to 50 lbs (including counterweights) for astrophotography.

Smooth RA and DEC Movement
The inside of the new SXD2 is very different from the previous SX Mounts. Bearings have been added to the shafts of t he RA and DEC axes and the screw gear shafts. The worm screw gears are inspected for strict concentricity and are lapped in the whole-circle for smooth movement.
