Skywatcher Dual-Speed Low Profile Crayford Focuser
A Low Profile CNC machined 10:1 dual-speed focuser designed for Newtonian Reflector telescopes of 9" to 15" aperture, and accepts either 1.25" or 2" eyepieces. Provides an exceptionally smooth focusing operation with the utmost precision, with the aid of its fine-focusing facility. 24mm Drawtube.
A high quality and very good value focuser. The one problem I had was that two of the four bolt holes were located partly underneath the focusing barrel making it very difficult to insert and tighten mounting bolts (which weren't even supplied with the focuser!). This appears to be a design fault. However, I've since seen photos of this focuser elsewhere that have the bolts holes in a more sensible/accessible position, so maybe a newer version is available. Ensure you check before ordering."
