i swapped out my focuser on my Dob and this is now surplus to requirements.
It's barely been used and is in excellent condition, no marks etc.
There is a base to suit a 33cm diameter tube but other bases are available from TS optics. The focuser unit is similar to this one from TS but for the Newtonian.
