Have I got one for you! Have used this for some years, connecting my old C8 to its original tripod mount (see photo of the wedge in action). I now have the genuine Celestron item so this home-made beauty is surplus to my needs. Built like a Sherman tank! Included are three bolts that will connect it to a Celestron tripod. Has a leveling bubble fixed to it. Currently set to 37 deg elevation, but readily adjusted - but no elevation scale on it.
Was $60. NOW ONLY $50
Pickup only in Melbourne. Either from Bundoora during the day, or I could drop off early evening close to my route (Bundoora to Bacchus Marsh, around Ring Road and out the Western Highway.)
