Refractor 140mm

Description:

Medium-size refractor that targets both visual astronomers, interested in top quality planetary views, and imagers alike.

The Super Planetary series correction is tuned specially for planetary-visual peak wavelengths. Paired with our Field Corrector for Medium Format, the 140 mm F/6.5 is suitable for imagers using sensors bigger than full-frame.
