Losmandy DM8 help!
I was trying to install the DM8 dovetail i have, i know the previous owner had successfully used it. But I cant work it out. The larger radius block seems to fit ok but the smaller one does not line up with the screws. I can use it but for the smaller block i can only use the central screw, however the two side screws would have to be removed and left partly uncovered. Is this normal?
