Starlight Instruments Feathertouch SCT Microfocuser

The Feathertouch SCT Microfocuser is designed for standard Schmidt-Cassegrain telescopes that utilize the common SCT thread connection. However, compatibility can vary based on the specific age and model of your telescope, so we recommend verifying your telescope's rear cell configuration before purchasing.

Most stock SCT focusers rely on moving the primary mirror, which can introduce image shift and mirror flop. This microfocuser provides a fine-focusing mechanism that allows for much smaller, more precise adjustments, significantly reducing image shift and making it easier to achieve critical focus for astrophotography.

Installation is generally straightforward and typically involves removing the existing focus knob and attaching the microfocuser assembly. While it does not require advanced technical skills, you should be comfortable handling small screws and following the included instructions carefully to ensure proper alignment.

The unit is crafted from lightweight aluminum, so it adds minimal weight to the rear cell of your telescope. While it is unlikely to significantly impact your mount's balance, you may need to make minor adjustments to your counterweights if you are already operating near your mount's payload capacity.

Yes, it is highly effective for both. For visual astronomy, it makes finding sharp focus on planets and double stars much easier, while for astrophotography, the fine-focus control is essential for locking in the precise focus required for high-resolution imaging.
