Reduces the focal length by a factor of 0.7x (at f/8) or 0.8x (at f/10). The reducer/corrector not only shortens the focal length but also flattens the field. Although originally designed for the Explore Scientific 127mm and 152mm ED-APOs, the reducer can be used on many systems. Comes with a 3" barrel and adapters for Nikon and Canon.
Flattens the field of view up to full-frame.
Can be adapted to many optical systems without coma, such as APOs, RCs, and Meade ACF.
