Vixen Optics improved on their Sphinx SXP Go-To EQ Mount by adding the STAR BOOK TEN computer control system and PF-L polar axis alignment scope to help you get set up and observing faster. The Sphinx mount is built in a center-balanced design so that the mount itself acts as part of the counterbalance system allowing smaller and/or lighter OTAs to be mounted without the use of the counterweights. Dual-axis stepper motors, 180-tooth brass worm wheels, and ball bearings, provide a smooth and precise tracking abilities with little to no vibrations.

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.

The addition of the HAL 130SXG tripod completes this observation rig, so all that is required is an optical tube assembly with a Vixen-style dovetail plate. The are made out of lightweight and durable aluminum to offer stability when open while maintaining its portability if it has to be carried any distance to the observation site. Its two-section legs adjust from 25" to 39" to accommodate a wide variety of users, and folds to just 32 inches. The mount and tripod have 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 35 pounds plus the counterweights.

  • Motorized German equatorial design
  • Vixen-style dovetail saddle accepts any compatible OTA
  • Center-balanced so the mount acts as part of counterbalance system
    • When using smaller OTAs, counterweights might not be required
  • Azimuth adjustment:
    • ±7°, fine adjustment
    • Twin tangent knobs, 1.2° per rotation
  • Altitude adjustment:
    • 0 to 70°

  • Proprietary Vixen Periodic Error Protection (VPEC)
    • Intrinsic errors are measured and entered into memory at the factory for precision tracking out of the box
    • Use with PPEC to boost tracking performance
  • Permanent Periodic Error Correction (PPEC) enables you to train out tracking errors for more accurate tracking over extended periods of time, such as long-exposure astrophotography
  • Backlash compensation allows you to train out the play inherent in all gears for more precise tracking
  • LAN port to update database via Internet
  • Powered by mount via controller cable
