This is an aberration-absorbing Schmidt telescope designed to provide aberration-free imaging for visualization and photography over large fields of view. This optical system not only reduces more off-axis coma, but also results in a flat focal plane and field of view edge play of the usual astrophotographer quality.

True astrophotographic quality 

Many optical designs claim that their telescopes have “astrophotographic” quality, but in fact only produce star points by curving the focal plane. This may be acceptable for visual observation, but when using the flat chip sensors of digital cameras, the stars are out of focus at the edges.

The optics provide a much flatter focal plane than a standard Schmidt-Cassegrain telescope and three times flatter than an ablative optic.

This ensures that you get sharp peripheral images through some of the largest CCDs available today - 

chips.

The superior edge-to-edge performance of the 

not only results in a more pleasantly moist star point, but also actually improves the separation and limiting magnification compared to telescopes of the same aperture.
