Starlight Instruments Feather Touch Micro Focuser for Celestron EdgeHD

This specific model is designed exclusively for the Celestron 14-inch EdgeHD telescope. It is not compatible with other aperture sizes in the EdgeHD line or standard SCT models.

Not at all. The unit is designed as a drop-in replacement, meaning it swaps directly with your existing focusing knob without requiring any permanent modifications or specialized tools.

The 10:1 reduction mechanism allows for incredibly fine adjustments that are nearly impossible to achieve with a standard single-speed knob. This precision is essential for locking in sharp focus during high-magnification visual observing or critical astrophotography sessions.

While this upgrade significantly improves the tactile feel and precision of your focusing, it does not mechanically alter the internal mirror assembly of the telescope. It is primarily designed to refine the focusing action rather than correct inherent mechanical issues with the telescope's primary mirror.

The unit is precision-machined from high-quality aluminum and stainless steel. This combination ensures smooth, reliable operation and long-term durability, even in fluctuating outdoor temperatures.
