Cassegrain telescopes are catadioptric systems, meaning that they use a combination of lenses and specifically shaped mirrors to form an image. Their designs take advantage of a folded optical path that reduces the size of the telescope, making them easier to produce and transport. The combination of lenses and mirrors also mean that the telescopes have an overall greater degree of error correction with a wider abberation-free field of view.

The two most popular Cassegrain designs are the Maksutov Cassegrain and Schmidt-Cassegrain telescopes. Without going into too much detail, the Maksutov Cassegrain telescope uses a corrector lens and spherical mirrors to correct off-axis aberrations and chromatic aberration. On the other hand, the Schmidt-Cassegrain telescope uses a spherical primary mirror and a Schmidt corrector plate to correct for spherical aberrations.

Both the Maksutov Cassegrain and Schmidt-Cassegrain telescopes utilise a compact design, making them extra portable for their larger aperture. They are suitable for lunar, planetary, and deep space observation, and are especially excellent for astrophotography as they have the best near focus capability among all the types of telescopes. Cassegrain telescopes are also durable due to their closed tube design and suited for land-viewing, making them one of the best quality and versatile telescopes available in the market.

Our range of Cassegrain telescopes for sale include both computerised and non-computerised mounts, and include well-established brands such as Celestron and Skywatcher. If you're unsure of what telescope is best suited for you, feel free to contact us and we will gladly assist you.
