APM Riccardi Universal APO Flattener 1.0x- Model 1 for APO Telescopes

Our new, universal flattener for APO’s was calculated with the famous optical designer Massimo Riccardi.

A flattener “smoothes” the optical problems in the image circle  caused by  coma and astigmatism, leading to a near perfect image quality . There is no comparable flattener with such good apochromatic longitudinal and lateral aberration correction on the market. Other cheaper models fall short significantly, leading to  drastically higher inferior lateral chromatic aberration and significantly higher vignetting.

The new flattener allows a generous working distance from the thread to the focus of more than 90 mm, allowing common accessories ( such as filter wheels) to find appropriate spacing.
