ikinci elipsoid ayna, birinci küresel aynadan
meydana gelen küresel sapinci düzeltmek için
gereklidir. Bu yapi Schmidt-Cassegrain türündeki
düzeltici yüzey ile Maksutov-Cassegrain türü
teleskoplardaki düzeltici menisküs
mercegin B-Dall-Kirkham Birinci ayna
ellipsoiddir, ikinci ayna küreseldir. This
design also includes one spherical surface. This
design was of interest in the past not so much to
reduce the number of optical surfaces requiring
figuring, but because the method commonly used to
test the hyperboloidal secondary of the classical
Cassegrain without required the availability of
an optical flat of similar size. A new method of
testing a convex hyperboloid, the Gaviola test,
has removed this obstacle to producing classical
Cassegrain telescopes. In the classical
Cassegrain design, the primary mirror is
parabolic, the secondary mirror is hyperboloidal.
And the focus of the secondary that lies behind
it coincides with the focus of the primary, so
that it follows from elementary geometry that
there is no spherical aberration for incoming
rays parallel with the axis. C-Ritchey-Chrètien

hiperboloiddir. 2- Bu tür telekoplar klasik
Cassegrain türü teleskoplara göre koma hatasi
azaltilmis oldugu için daha avantajlidir.

• Dall-Kirkham Koma.
• Ritchey-Chretien Sifir coma. Ikincil ayna
  yapimi zor.
• Schmitt-Cassegrain No coma or astigmatism, but
  has severe spherical aberration and field
  distortion. Uses a third optical element, a
  corrector plate, to retard the wavefront to
  correct for spherical aberration.
