About this product

Model:  ts_tsflat2
Part Number:  TSFLAT2

The TS FLAT2 is a Field Flattener designed for APO/ED and Fraunhofer Refracors. 

The corrector is suitable for refractors with focal ratios of f / 4 to f / 9. 

The TSFLAT2 offers several advantages:

  • Very good illumination, can be used with full format sensors
  • Generous back focus distance of between 108mm to 128mm - depends on the focal length of the telescope
  • M48x.75 - 2" Filter thread connection on both Telescope and Camera sides
  • 2" Pushfit - fits any 2" focuser

Recommended back focus distances from the M48x0.75 thread to the corrector

The shorter the focal length of the refractor, the longer the back focus distance to the sensor.

  • Focal Length <450mm: 128mm
  • Focal Length 450-490mm: 123mm
  • Focal Length 500-550mm: 118mm
  • Focal Length 560-590mm: 116mm
  • Focal Length 600-690mm: 113mm
  • Focal Length 700-800mm: 111mm
