The FeatherTouch SCT MicroFocuser by Starlight Instruments provides the smoothest control for fine focusing for Celestron (non-CPC) SCT 9.25-inch telescopes.
Two focus knobs allows for standard or 1/10th-speed focusing, making the MicroFocuser extremely accurate. Excellent for both imaging or visual observing, this focuser is precision-machined and anodized black with a brass fine-focus knob.
The SCT MicroFocuser is easily installed in place of the original focus knob on Celestron 9.25-inch telescopes. This model is not compatible with the CPC version, however.
If your telescope is less than a few years old, check the style of the back cell to see which version of the FeatherTouch SCT Micro Focuser you need: If your telescope has a flat back , you need the standard "C" Micro Focuser. If your telescope has a triangular pattern on the back, you will need the "CPC" version of the MicroFocuser.
