TS-Optics 2" Crayford Focuser for Schmidt-Cassegrains

TS-Optics 2" Crayford Focuser for Schmidt-Cassegrain telescopes

• Due to the Crayford friction principle, the focuser is absolutely shifting-free and impresses with its excellent workmanship. The drag is adjustable so that accessories weighing up to 2 kg can be focused well.
• Move the camera or eyepiece into the correct orientation without loosening the clamps. Use an off-axis guidre to find the guide star without loosening the camera. This makes 360° rotation possible. Simply loosen the knurled screw at the front of the focuser and you can simply turn the complete focuser.
• 2" accessories are clamped using a brass compression ring. Of course, a high-quality reduction to 1.25" with thread for 2" filters is included in the price.
• The adjustment range is approx. 25 mm - that is more than enough. One adjusts roughly with the main mirror focusing, all other fine adjustments can then be made with the focuser.
  
  Note:
  The focuser only works on telescopes with at least 8" aperture, otherwise the focusing knob is too close to the thread to allow mounting.
