hi
i have the 200mm f/5 sw in blue.
i did not reach infocus on mine, so i changed it to a cheapish low-profil 2 speed crayford from orion, but i have seen that skywatcher also sell them under their brand now.
like this one

its much smoother, and easyer to hit focus with.
here are the adaptors you need
