Great focuser

Wednesday, 9 March 2022 | William

I bought the long travel version of this direct from TS a while back. It is excellent and the long focus range makes it able to cope with 3 different reducers and visual configs of my APM 107mm refractor. Really smooth and stable; takes a heavy load, and it saved me a packet over a Starlight.

By default it comes with a 117mm screw connector for on ota but it uses a more standard 105mm plug intermediate connector that can be adapted to various OTAs. You would want the different short travel version for RC scopes.
