Starlight Instruments Micro Pinion Assembly

It is designed to eliminate the mechanical 'slop' or 'creep' often found in stock focuser assemblies. By replacing the standard components with this precision-engineered version, you gain significantly smoother, more stable control, which is critical for achieving sharp focus during imaging or high-magnification visual observation.

No, it is specifically engineered for Takahashi 2.7-inch focusers. It is compatible with models including the Takahashi 102, FS102, TSA120, FS-128, TOA-130, and 152N.

The assembly is designed as a straightforward retrofit for your existing focuser. While it requires basic mechanical aptitude to swap out the factory components, most users find it to be a manageable upgrade that does not require specialized tools.

Yes. Because this assembly provides a more precise and stable connection, it is better equipped to handle the weight of heavier cameras and imaging accessories without slipping or shifting during your session.

This specific assembly focuses on refining the pinion mechanism itself for smoother, more accurate manual control. It is intended to improve the tactile experience and precision of your existing focuser rather than adding a new dual-speed reduction system.
