Designed to give astrophotographers maximum performance and easy portability, the precision hardware of the SXP2 Sphinx GoTo EQ Mount from Vixen Optics gets a performance boost by adding the PF-L polar axis alignment scope and Star Book Ten (SB10) computer control system to boost alignment, GoTo, and tracking accuracy. Micro stepper motors with a belt-drive system, 180-tooth brass worm wheels, and ball bearings provide smooth and precise tracking abilities with virtually zero vibrations or backlash.
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 SB10 controller can be used to provide full GoTo capabilities with a color display and intuitive menu system. Outfitted with an internal and updatable 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 with Permanent Periodic Error Correction (PPEC), Vixen Periodic Error Correction (VPEC), and backlash to improve the precision of the tracking system during long-duration observation sessions and which gets better the more you use it.
The addition of the HAL 130SXG tripod completes this observation and astrophotography rig, so all that is required is an optical tube assembly (OTA) with a Vixen-style dovetail plate. It is 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 it folds up to just 32". The mount and tripod have a maximum payload capacity of 60 pounds for observation purposes, but if this rig will be used for astrophotography or imaging, Vixen recommends the max payload be kept to 50 pounds excluding the two included counterweights.
