The results are simply amazing: a telescope that offers a wide, flat focal plane (more than 65 mm in diameter, even in the smallest model!). A wide focal plane that is diffraction limited over a wide spectral range.

Since the corrector group is close to the focal plane, chromatic aberration is undetectable.
