This Used Meade SuperWedge has seen some action, but it is built very well and will work perfectly with Meade 10" & 12" Schmidt-Cassegrain telescopes. Please Note that no additional hardware is included. See pictures to determine the hardware you will need. A good source for miscellaneous astronomy hardware is scopestuff.com.
Here is some information about the Super Wedge from Meade Instruments:
The Superwedge permits use of the 10" and 12" LX200 telescope in an astronomical, or "equatorial," mode. The wedge fits onto the field tripod, described below, and accepts the base of the 10" and 12" LX200 fork mount.
NOTE: The Meade Superwedge is designed solely for use in conjunction with the Meade field tripod. The Superwedge should never be used without the field tripod, e.g. by placing the Superwedge alone on a table top and then mounting the telescope on the wedge. The 10" and 12" LX200, placed onto the Superwedge alone without the field tripod attached to the wedge may become seriously imbalanced, to the point where the telescope may actually tip over.
The Superwedge for the 10" and 12" LX200 telescope is of modern design, with several important features incorporated to simplify and facilitate telescope operation. After using the Superwedge for your telescope, you will find that the functional design features included are of very significant value in routine telescope operations.
