AstroFrog 2 Inch Dual Speed Gear Focuser Telescope Focuser for SkyWatcher Newtonian Reflector

The focuser is one of the most important components of an astronomical telescope. It is responsible for the focusing and alignment of the telescope's rear-end optical system, eyepiece, or imaging equipment. Its load capacity, stability, and adjustment feel directly affect the optical performance of the entire telescope.

After years of research and development in telescope focuser design, our studio is dedicated to creating the ultimate precision focuser. This 2-inch geared dual-speed focuser is the result of our pursuit of superior performance and precision.

* All components are manufactured using CNC precision machining to ensure higher assembly accuracy.

* Equipped with a 2-inch coaxial locking system to guarantee precise concentricity.

* Features a M54 x 0.75 standard thread, compatible with field flatteners.

* Uses a sliding mechanism with a light-blocking design to prevent stray light leakage.

* Four red precision components on the side of the main body improve sliding accuracy and vertical alignment.

* Eight hidden precision bearings provide smooth and stable operation.

* The internal surface features a CD-pattern matte finish for effective stray light suppression.

* High-precision small module custom gear and rack transmission effectively eliminates backlash.

* The left-side blue fine adjustment knob provides variable-speed micro focusing with a 10:1 reduction ratio for ultra-fine focus control.

* 1 x Newtonian Telescope Focuser

* Package weight: 2kg
