#19230 - Libra Alt-Azimuth Adjusting D-Plate.

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 Alt-Az mount was designed to make this alignment task simple and painless.  Using a pair of clamps on one side to attach the female dovetail receiver to an existing male D-plate, the #19230 will fit directly on to any "D" style dovetail bar.  A second pair of larger knobs on the opposite side provide both altitude and azimuth adjustments.  A locking thumb nut secures the fine thread adjustment shaft for easy "no tools" installation and configuration.
