The Synta 2″ Dual Speed Focuser for 8″ or 10″ Newtonians is a smooth dual-speed focuser with a 10:1 gear ratio. The Crayford-style focuser uses a roller rather than a rack and pinion which applies backlash-free movement to the focuser drawtube.
If you have a single-speed focuser on your Dobsonian or Newtonian telescope, you will appreciate the finer control that the dual-speed focuser gives you. Lunar or planetary astrophotographers will find this a must-have upgrade.
Replace your old Rack and Pinion or single speed Crayford-style focuser to achieve finer focusing capability.
Compatible with all Sky-Watcher and saxon 8 or 10 inch Newtonian telescopes. Also suitable for DIY telescope projects.
