Takahashi TKA00705 – Universal Rack & Pinion Focuser (50.8mm)

Heavy-duty precision for Mewlon and CN scopes using 2" accessories

Cloudy Nights Community Insight

One longtime observer shared that installing the 50.8mm Takahashi focuser was like “removing a bottleneck in the optical train—it opened the field without losing a bit of that legendary Tak sharpness.”

Observing Tip

With a 2" diagonal and something like a 30mm wide-angle eyepiece, this focuser turns a Mewlon into a galaxy sweeper that still holds tight at high power. Lock your target in with no drift, and you’ll feel the upgrade every time you rack in or out.
