Vixen Optics SX2 SBT Equatorial Mount

Vixen Telescope SX2 Mount Description Declination body acting as part of counterweight. The massive motor units are placed in the lower part of the declination body so that the center of balance of the SX2 shifts below the intersection of the RA and Dec axes. This makes the lower portion of the declination body perform as a counterweight and allow the mount to work with less counterweight.
