Hi all
Everytime i tighten the focus lock on my new Skywatcher ED120 the focus shifts. Not happy.
Thinking of Ditching my factory supplied crayford focuser and replacing it with a suggested Moonlight focuser.
Can anyone direct me to somewhere on the net that shows how you take the old focuser off and fit the new one without deystroying ones expensive investment?
Please understand you are dealing with a man with 5 thumbs and technical ineptitude and i mean inept.

Regards
Carl
