Vixen Optics Sphinx SXD2 Go-To EQ Mount with Polar Scope

Designed with similar specifications as their beefier SXP mount, this lighter-duty Sphinx SXD2 Go-To EQ Mount from Vixen Optics gets a performance boost by adding the STAR BOOK TEN computer control system and PF-L polar axis alignment scope. Dual-axis stepper motors, 180-tooth brass worm wheels, and ball bearings provide smooth and precise tracking abilities with little to no vibrations. The mount has a maximum payload capacity of 50 pounds for observation purposes, but if this rig will be used for astrophotography or imaging, Vixen recommends the max payload be kept to 33 pounds, including the counterweights. This iteration of the Sphinx is offered here without a tripod for users that already have a reliable and compatible support system.

The included polar axis scope has an illuminated star-pattern reticle that requires the user to simply superimpose the star pattern over the three prominent stars over the North Pole for proper polar alignment. With this simple alignment done, the STAR BOOK TEN controller can be used to provide full Go-To capabilities with a color display and intuitive menu system. Outfitted with an internal and updateable database of over 272,000 objects, the SB10 offers phased star charts, customized guided tours of the night sky, and the ability to program out tracking errors (PPEC and VPEC) and backlash to improve the precision of the tracking system during long-duration observation sessions.
