About this product
Part Number: TSFOCR25
The TS 2.5" Rack and Pinion Focuser is a high quality 2.5" focuser with a max payload capacity of 6kg
Telescope side connection - M90x1 female thread:
The TS 2.5" rack and pinion focuser is attached to the telescope via an M90x1 female thread adapter. 360° rotation is also included - with no tilting. The connection fits directly to the 6" and 8" Stella Lyra Ritchey Chretien and Cassegrain telescopes.
Camera side / eyepiece side connection:
The TS 2.5" rack and pinion focuser has an M63x1 connection thread on the camera side. This allows direct screwing of corrector systems like the TS 2.5" full-frame flattener for refractors or Stella Lyra Ritchey Chretien telescopes
In addition, a 2" eyepiece adaptor is included (compression ring with 3 screws) and a 2" to 1.25" adaptor is also included.
