Starlight Instruments Focuser Accessories

Starlight Instruments focuser accessories are the parts that fit a Feather Touch focuser to a specific telescope and connect it to the rest of your train. Telescope adapters exist for many refractors, including Takahashi FSQ85 and FSQ106N, Sky-Watcher Esprit and Equinox, William Optics FLT and Explore Scientific models.

Threaded end caps such as M68 and M48, flat and curved bases with leveling screws, and PTFE coupled collars complete the range.
