focuser slippage
Hi all,,I recently bought a second hand W/O 2speed crayford focuser in great cond,,when i load it up with a large EP and W/O 2" Diag the focuser SLIPS and won't adjust,,It works with "lighter" EP's,,I have completely loosened the silver "hold" screw and tightened the black focus pressure screw,,it has made a mediocre difference,Is there anything else i can do to "tighten" it up more to stop it SLIPPING,,,Thanks all,,,MAT
