APM


 

The APM Riccardi 1.0x Apo Flattener Model 1 is a high quality triplet ED flattener for short apochromatic refractors. This model is suitable for refactors with focal ratios faster than f/7 and focal lengths below 1000mm.

Designed by legendary optical designer Massimo Riccardi, this flattener provides a fully illuminated field of 60mm. It features exceptionally good correction of longitudinal and transverse aberrations with truly apochromatic performance. It has a large backfocus distance requirement of more than 90mm, making it possible to use a wide range of accessories such as rotators and off-axis guiders.

The APM Riccardi Flattener features state-of-the-art multi-coatings optimized for the spectral range of modern sensors.
