Takahashi focusers and focusing upgrades for Takahashi refractors, Mewlon Dall-Kirkham Cassegrains and CN-series optical tubes. The range covers MicroEdge dual-speed micro-focusers and universal rack-and-pinion focusers in both 36.4 mm and 50.8 mm (2″) drawtube sizes, so you can match the focuser to the eyepiece or imaging train the telescope already carries.
A focuser upgrade matters most where fine focus is hard to hold: long-focal-length planetary work, high-magnification visual observing, and any imaging train heavy enough to make a single-speed focuser awkward. Dual-speed micro-focusers add a fine reduction stage for precise focus placement, while rack-and-pinion focusers add drawtube rigidity under load.
If you are not sure which focuser fits your tube, send us your telescope model and we will confirm the right one before you order.
