Stellarvue SVF25 2.5” Rack & Pinion Focuser
for Refractors with M88.5x1 Threads
The SVF25 Focuser is the same one used on Stellarvue's beautiful high-quality triplet refractors. This 2.5" dual speed, fully rotating rack & pinion focuser features 80 mm of travel and is threaded for any Stellarvue field flatteners that have the -25 designation. A 2" and 1.25" eyepiece adapter is included for visual use.
The Stellarvue SVF25 2.5" Focuser attaches to Stellarvue telescopes that use the standard M88.5 X 1 thread. Examples of telescopes that may be used with this focuser include the Nighthawk Next Generation, SV90T (not SVR90T), SV90TBV, SV102ED, and some SV105s. Not all SV telescopes will operate with this focuser, so if you're not sure, please give us a call or start an online chat and we will help you figure it out.
