  • Description

    The Vixen Sphinx SX2 Equatorial Mount is simple to operate and sets up in minutes. One bolt secures it to the tripod. Beginners and seasoned hobbyists will benefit from the portability of the Vixen SX2, the easy-to-use STARBOOK One controller, and the ability to download future upgrades directly to the controller.

    The SX2 equatorial mount with dual-axis drive attaches to a variety of telescopes with the Vixen universal dovetail plate. The short profile declination head and internal motors greatly improve balance and motion around the RA axis, guaranteeing precise motor control. Small telescopes require no additional counterweights due to the internal placement of the the RA and DEC motors. The counterweight shaft retracts into the SX2 mount body for storage when not in use.

    STAR BOOK ONE & HAL-130 Tripod Features

    The STAR BOOK ONE Controller is a dual axis handheld controller. The 4 buttons on the controller move the mount electrically in the X and Y axis (RA and DEC). The controller includes a built in red LED light for illumination to avoid loosing night vision. Versatile tracking options are available; sidereal rate, Kings Rate, lunar rate, and solar rate. Different tracking speeds are available for time lapse photography. The controller works in both the northern and southern hemispheres. Backlash compensation provides reduced time lag at the point of reverse motion and the controller can be used for auto guiding with an auto guider compatible with SBIG auto guiders. PEC rectifies irregular motion of the tracking gear wheels that affect long exposure astrophotography.

    The HAL130 Tripod provides ample stability and has no wobble points in its design. The HAL130 has a large base to carry the Sphinx SX2 mount. The tripod extends from 32" to 51" (81cm to 130cm) and weighs 12 lb.(5.5 kg).
