Not to scale.).

The convex secondary mirror multiplies the effective focal length of the primary mirror and results in a focus at the focal plane, with light passing through a central perforation in the primary mirror. The Meade 8", 10" and 12" Schmidt-Cassegrain models include an oversize primary mirror, yielding a fully illuminated field- of-view significantly wider than is possible with a standard-size primary mirror.
