The mirror needs to be run up and down the baffle tube every week or so to spread the grease/ glue and minimise mirror flop.
You still had slight mirror "slop" while reversing focus direction, but with experience and practice that could be minimised...
It's only because I could relocate my 12" OTA (>17Kg) onto the NEQ6 that I sold all the Meades and went for a C11.

Thanks for the advice Ken!
Is there a youtube tutorial or something similar that shows the mod?
Cheers,
Justin.
