Skywatcher Dual Speed Crayford
This excellent smooth dual speed replacement focuser (10:1 gear ratio) suits Sky-Watcher Newtonian (Dobsonian) telescopes sold without dual-speed capability.
Especially if you’re in to 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 n 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 and T-thread adaptor.
The focuser fits directly to the most Skywatcher Newtonian telescopes.
Hole spacings 86.5 mm x 78 mm so it can be as simple as bolt off / bolt on.
