The Starlight Instruments SCT MicroFocuser provides the smoothest control for fine focusing. 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 most Celestron 8" SCTs. A built-in stop prevents the primary mirror from detaching from the focuser. The SCT MicroFocuser will not fit old orange-tube C8 telescopes.

This model is not compatible with the new CPC-800 or NexStar 8 SE telescopes from Celestron. A new CPC-800 compatible model is available.
