Consists of a standard Meade equatorial wedge, plus an adapter plate to accomodate the Meade LX90 drive base.

Allows mounting an LX90 in a polar mode on the scope tripod for long exposure deep space astrophotography (which is otherwise not possible when the scope in its default altazimuth mode). The wedge is not needed for short exposure lunar and planetary photography. 

Comes with a deluxe latitude adjuster and azimuth fine adjuster for precise polar alignment. Also includes no tool knobs for easy assembly of the wedge to the tripod and the scope to the wedge, plus a compass for faster aligning on the pole. Made of die cast aluminum.
