My Superwedge is made from 12mm thick Durallumin plate. The wedge, base & side plates are C.N.C. waterjet profiled and assembled to a high standard in our workshop. Both the Azimuth and Declination shafts are of stainless steel and are fitted with thrust roller bearings to give smooth action.
Each shaft is fitted with a large hand wheel for more precise control. Also after adjusting the polar alignment the screws in the end of the pivot shaft and the telescope mounting plate (these are the two that run in the adjustment slot) do not require tightening therefore no movement can occur after the pole star is in the required place in the eyepiece.Back
