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
