It is possible to combine the features of the previous designs to come up with new types. In the December 2001 issue of "Astronomy" magazine, Mead just announced the introduction of their new line of Schmidt - Newtonian telescopes. While not a new design, it is one that has never been mass produced before. They offer a 6" f:5, an 8" f:4, and a 14" f:4 model of this telescope type.
These telescopes use a Schmidt corrector plate with a spherical main mirror that does not have a hole in it for a Cassegrain type focus. A small flat secondary mirror is mounted at a 45° angle in the center of the Schmidt Corrector Plate.
