Cheap upgrade to skywatcher heritage

[Enrico]

Can't claim to have thought of this myself - read it on another very old thread but thought it worth to re-post for another new heritage owners like me out there.

The simple upgrade is - PTFE tape (the stuff plumbers use). Wind a bit around the thread of the focusser (one thickness across the whole tread worked for me). This gives the focusser a much more positive feel, and reduces the small amount of "slop" that you can otherwise get with this otherwise excellent scope.
