This smooth dual speed focuser (10:1 gear ratio) suits Sky-Watcher Newtonian telescopes. If you’re into lunar and planetary imaging with an f/5 newtonian, then this focuser is a must-have upgrade. Now you can replace your old Sky-Watcher Rack and Pinion or single-speed Crayford style focuser to achieve finer focusing capability. Also suitable for DIY telescope projects.
Includes dual speed 2-inch focuser, 2 inch dust cap, 2 inch to 1.25 inch adapter. Hole spacing 85mm x 85mm.
