Takahashi Universal Rack & Pinion Focuser (36.4mm) (Mewlon/CN) TKA00700

Takahashi TKA00700 – Universal Rack & Pinion Focuser (36.4mm)

Precision control for Mewlon and CN instruments

Takahashi doesn’t rush anything—and that’s especially true when it comes to focusers. The TKA00700 Universal Rack & Pinion Focuser is a fine example of Japanese craftsmanship applied to the most tactile part of the observing experience. Designed with a 36.4mm threaded drawtube, this focuser brings smooth, mechanical precision to Takahashi’s smaller instruments, including the Mewlon series and CN scopes.

What sets it apart? You won’t find a whisper of backlash. The helical-cut rack meshes cleanly with the pinion gear, translating every fraction of a turn into deliberate, fluid motion—ideal for high-power visual observation or fine planetary focusing where split-second detail matters.

This isn’t a one-size-fits-all aftermarket fix. It’s a factory-fit upgrade, meant to integrate seamlessly with your Takahashi OTA and elevate it from capable to unforgettable.

Key Features:

• Designed for Takahashi Mewlon and CN instruments

• 36.4mm drawtube threading for direct compatibility

• Helical rack & pinion gearing for fine, backlash-free control

• All-metal build with Takahashi’s signature attention to detail

• Ideal for high-magnification visual work or basic imaging loads

Cloudy Nights Community Insight

A 6" Mewlon user noted that swapping in the TKA00700 focuser “felt like upgrading the instrument itself—tight, crisp motion and no drift when switching eyepieces.”

Observing Tip

This focuser’s sweet spot is under the stars at 250x or higher—especially when planetary detail matters. A well-made eyepiece, paired with this R&P unit, turns your OTA into a surgical instrument.
