Cassergrain Telescopes

Schmidt -Cassegrain Advantages   

  • Best all-around, all-purpose telescope design. Combines the optical advantages of both lenses and mirrors while cancelling their disadvantages.
  • Excellent optics with razor sharp images over a wide field.
  • Excellent for deep sky observing or astrophotography with fast films or CCD?s.
  • Very good for lunar, planetary and binary star observing or photography.
  • Excellent for terrestrial viewing or photography.
  • Focal ratio generally around f/10. Useful for all types of photography. Avoid faster f/ratio telescopes (they yield lower contrast and increase aberrations). For faster astrophotography, use a Reducer/Corrector lens.
  • Closed tube design reduces image degrading air currents.
  • Most are extremely compact and portable.
  • Easy to use.
  • Durable and virtually maintenance free.
  • Large apertures at reasonable prices and less expensive than equivalent aperture refractors.
  • Most versatile type of telescope.
  • More accessories available than with other types of telescopes.
  • Best near focus capability of any type telescope.

Schmidt-Cassegrain Disadvantages

  • More expensive than Newtonians of equal aperture.
  • It is not what people expect a telescope to look like.
  • Slight light loss due to secondary mirror obstruction compared to refractors.
