The results are simply amazing: a telescope that offers a wide, flat focal plane (80 mm in diameter, with 145mm backfocus extraction). A wide focal plane that is diffraction limited over a wide spectral range. The corrector group is very close to the focal plane, so chromatic aberration is undetectable.
