Rainbow Astro RSF-8 Motor Focuser: Advanced Focusing for 8-inch RC Telescopes
Designed for Reflecting Telescopes: Specifically created as a secondary mirror moving motor focuser for RC 8", 10", and 12" OTAs (Optical Tube Assemblies).
DIY Friendly: Comes as a DIY kit, allowing users to easily attach the focuser to their telescope without causing any damage.
No Impact on Telescope Performance: Its design ensures that attaching heavy cameras does not affect the focuser's or the telescope's performance.
Improved Collimation: Replaces traditional focusers to reduce disturbances, thereby enhancing precise collimation.
Built-in Home Sensor: Features a home sensor for the focuser to automatically find its mechanical origin, ensuring accuracy and ease of use.
Included Hand Controller: Offers a hand controller for convenient manual operation, particularly useful for visual observations.
ASCOM Driver Support: Compatible with ASCOM drivers, allowing for seamless integration with various astrophotography software.
Versatile Compatibility: Suitable for both tube type and truss type RC telescopes from manufacturers like GSO, Astro-Tech, and TPO.
Cost-Effective Solution: Provides the advanced functionality of a secondary mirror moving focuser at the price of a normal focuser, including motors and controllers.
Enhanced Astrophotography and Observation: Ideal for astrophotographers and observers looking for a high-quality, reliable focuser upgrade for their 12-inch RC telescopes.
