Open Box Vixen Sphinx SXD2 EQ Mount w/Starbook 10 & Tripod - SOLD

Vixen has reworked the design and manufacture of its innovative SXD Mount. The SXD2 Mount has a greater loading capacity and is more rigid, enabling a more steady platform for astrophotography. The quieter stepping motors ensure you of smooth, quiet slewing with quick response to commands.The Star Book Ten features an intuitive Star Chart Go-To System on a high definition LCD Screen. Features include night vision screen, hibernate mode, VPEC and PPEC, and even an optional built in auto-guider. 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 pounds (including counterweights) for astrophotography. Smooth R.A and DEC Movement: The inside of the Vixen Sphinx SXD2 is very different from the previous SX equatorial mounts. Bearings have been added to the shafts of the 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. Unique Mount Design: The Vixen Sphinx SXD2 Mount is designed so that the mount body acts as part of the counterweight system. Periodic Error Correction: Data from your PE correction input is saved for your next observing session. Polar Axis Scope: The Sphinx SXD2 Mount includes a built-in 6x20 polar axis scope. It has an 8 degree field of view, a bubble level, an illuminated reticle, and accuracy to within 3 minutes.
