Designed especially for smoother imaging, our new precise, dual speed rack and pinion focusers now come standard on all Stellarvue telescopes. Our 2.5” focusers are fully rotating with large rotation collars and thumb screw. Tension control thumb screw underneath holds tight and eliminates all side play.

For visual users, these focusers are ultra smooth and free of vignetting. For imagers, our dedicated field flatteners thread directly into each focuser, maintaining precise alignment.

Contact us to upgrade your older Stellarvue or other brand refractor using our newest and best focusers ever.  For more information call us at (530) 823 7796.

SVF25 2.5” Dual Speed, Fully Rotating, Rack and Pinion Focuser

Featuring 80 mm of travel, this focuser is an ultra-precise dual speed unit that is threaded for our SFF7-25 and SFF25 photographic field flatteners. For visual use, our precision compression ring 2” and 1.25” adapters are included. Attaches to our telescopes with our standard M 88.5 X 1 thread so this focuser can be a direct replacement for many Stellarvue refractors including the Nighthawk Next Generation (standard and deluxe), SV90T, SV90TBV, SV102ED, and some SV105’s. It will also work on any of our former 102 telescopes but may require a separate adapter (check with us on your particular telescope).
