TS-Optics 2" CCD Reducer 0.67x for RC & flatfield telescopes from F/8
US$ 226.32
The 2" CCD compressor reduces the focal length of telescopes with the factor 0.67x, thus allowing significantly shorter exposure times.

♦ The focal reducer is perfectly suitable for RC telescope. It also works good with Celestron EHD or Meade ACF telescopes or with refractors up to the focal ratio F/9
♦ The image field of DSLR cameras up to APS-C format is illuminated - full illumination up to 29 mm
♦ Easy connection to the telescope via 2" barrel
♦ Optimal working distance from the M48x0.75 thread to the camera sensor is 85 mm - enough space for accessories like off-axis guider or filter wheel
♦ 2" filter thread at the telescope side
