Designed specifically for the Sky-Watcher Esprit-120 ED apo refractor, the new three-lens focal reducer / flattener has a reduction factor of 0.77x. It comes with a standard adaptor with M48 thread edge and 55 mm back focus for use with Sky-Watcher´s M48 Canon EOS (code 20237) and Nikon (code 20238) adaptor rings.

After removing the adaptor, an M71x1 internal thread with maximum 75 mm back focus is available for self-made adaptor solutions.
