Telescopes

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. This is achieved by employing a hyperbolic secondary mirror, delivering very good images also away from the optical axis.

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

ACF optical systems show their strengths, especially in astrophotographic applications.
