TS Optics Focuser Crayford 2" (11264)

The TS Optics Crayford 2" Focuser is specifically designed for Schmidt-Cassegrain telescopes, addressing the common issue of mirror shifting that can make precise focusing difficult during astrophotography or critical observation. By utilizing the Crayford friction principle, this focuser ensures smooth, shift-free operation and supports accessories weighing up to approximately 4 kg. Its robust construction, micro-focusing capability, and convenient features make it an excellent choice for both amateur and advanced astronomers seeking reliable and accurate focusing performance.

Product Features:

Micro Transmission (1:10 Ratio):
The focuser includes a 1:10 micro transmission for highly precise focusing. One full turn of the micro knob moves the drawtube by 1.4 mm, while a 10° turn results in just 0.038 mm of movement, making it suitable for even the most demanding applications.

360° Rotation:
You can rotate the entire focuser and its attached accessories by simply turning the knurled knob on the telescope side, without loosening any locking screws. This is especially useful for adjusting the orientation of a star diagonal, camera, or off-axis guider.

Drawtube Locking Mechanism:
The drawtube can be locked firmly in place, disengaging the focusing mechanism. This feature is particularly important for astrophotography to keep the focus stable.

Travel Distance:
The focuser provides a travel distance of approximately 25 mm. Coarse focusing is performed with the telescope’s main mirror, while fine adjustments are made with the Crayford focuser.

1.25" Reducer Included:
A reducer from 2" to 1.25" with a brass clamping ring and a 2" filter thread is included, allowing compatibility with a wide range of eyepieces and accessories.
