Who knew the ParaCorr did not work on classical cassigrain optical systems? Well I didn't. Like new in box but with a small mod to get rid of the focuser assembly wiggle. Mod was to install two black 6-32 nylon set screws on the back side of the eyepiece assembly barrel to even out the pressure of the one factory clamping screw. Has no effec on optical train except to improve alignment of eyepiece by taking out all the wiggle. All caps, plugs, datasheet and origional box (if I can find it). Pics available. $250 shipped US.
