Glossary | Telescopes | Optics | Type of build | ACF-Cassegrain

Meade's ACF optical design eliminates the typical aberrations of all mirror optics. Thanks to ACF, the stars are also point-shaped right out to the edge of the image field, displaying no elongated comet-like distortions.

The image field is flatter than that of classic Schmidt-Cassegrain telescopes.

ACF optical systems show their strengths especially in astrophotographic applications.
