Stellarvue and Feathertouch Focusers

STELLARVUE FOCUSERS

Designed especially for smoother imaging, our new precise, dual speed rack and pinion focusers now come standard on all Stellarvue telescopes. Choose either the 2.5” or 3”. Both 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. Adapters are additional.

STELLARVUE SVF FOCUSERS
	SVF25 2.5” Dual Speed, Fully Rotating, Rack and Pinion Focuser Featuring 3.5” 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 with our standard M88.5 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 SV105. It will also work on any of our 102 telescopes but may require a separate adapter (check with us on your particular telescope). #SVF25 - $265 THE SVF25 IS STANDARD ON THE SVR90T RAPTOR AND MANY OTHER STELLARVUE TELESCOPES
	SVF25 2.5” Dual Speed, Fully Rotating, Rack and Pinion Focuser Direct replacement for many early model Stellarvue telescopes This is the same focuser as shown above but the attachment collar is machined to work with many of our early model telescopes including: The AT1002, AT1010, Nighthawk Classic, Nighthawk 2, 80/9D, SV85S, SV85L. #SVF25-NH - $265
	SVF25 2.5” Dual Speed, Fully Rotating, Rack and Pinion Focuser Direct replacement for Orion or Synta ED80 This is the same focuser as shown above but it also has an attachment adapter that fits the popular ED80 telescopes. Merely remove the focuser (by unscrewsing the three screws) and install this focuser using the same three screws. In under a minute you have a larger, smoother, higher capacity focuser with 2” and 1.25” visual adapters and you can directly thread our Stellarvue SFF25 to the focuser for imaging without focuser sag. #SVF25-ED80 - $295
	SVF30 3.0” Dual Speed, Fully Rotating, Rack and Pinion Focuser Featuring 3.5” of travel, this focuser is an ultra-precise dual speed unit that is threaded for our SFF7-3 and SFF30 photographic field flatteners. For visual use, our precision compression ring 2” and 1.25” adapters are included. Attaches with our standard tapered base or adapters can be made for modifying your telescope and improving its performance. This focuser directly attaches to many Takahashi telescopes. Check with us. #SVF30 - $399
FEATHER TOUCH FOCUSERS
	FEATHER TOUCH 2” CRAYFORD FOCUSER WITH REFRACTOR BRAKE AND 2.5” OF TRAVEL This is the same 2” reverse-Crayford focuser we sold for years on most of our telescopes. It is a small and smooth unit that is about as dependable as it gets. Check with us to see if we can custom adapt this focuser to any existing refractor you own. Adapters are additional. #FTF2025 BCR - $385
	FEATHER TOUCH 2.5” RACK AND PINION DUAL SPEED FOCUSER WITH 3.5” OF TRAVEL This is a direct replacement for the SVF25 focuser. With our custom adapter it will work with our older style 80-105mm Stellarvue refractors. #FTF2535HD - $615
	FEATHER TOUCH 3.0” RACK AND PINION DUAL SPEED FOCUSER WITH 3.5” OF TRAVEL Very similar to the FTF2535 above but this one is 3”. Will work with many older style Stellarvue telescopes with some adaptation or with many other refractors on the market with adapters. #FTF2535HD - $645
	FEATHER TOUCH 3.5” RACK AND PINION DUAL SPEED FOCUSER WITH 4.5” OF TRAVEL This is the same focuser used on the venerable Stellarvue SV160 Apo Triplet. #FTF2535HD - $885
