Big Bubba HD Alt-Az adjustable telescope base.
Aligning two co-axial telescopes has always been a challenge. Scope rings require adjusting up to six individual screws to provide alignment. Then the slightest bump can knock the telescopes out of alignment. The Libra HD mount was designed to make this alignment task simple and painless for even the largest scopes. A pair of large knobs provide both altitude and azimuth adjustments. A set of bolts and screws allow the system to be locked down, preventing any shifting.
Changeable Plate. +/-2 Degree Altitude and Azimuth Adjustment. 50+ lbs payload.
