There was a time when astrologers were limited to old-school technology of either reflecting telescopes (also known as reflectors) or refractor telescopes (also known as refractors) but now the technologies have provided them with most recently invented catadioptric telescopes.
Catadioptric telescopes include a fusion term that indicates a system combining both the lenses and mirrors, i.e., reflectors and refractors, to form an image and transmit it to the eyepiece and, in turn, its viewer. In simpler words, a catadioptric telescope is an innovative combination of a reflecting telescope and a refracting telescope, thus providing the benefits of both the telescopes.

The Celestron NexStar 4SE is basically a scaled-up version of Celestron’s C90. Being a Maksutov-Cassegrain, its robust design uses a speedy spherical primary mirror along with a meniscus corrector lens. There is also an aluminized “spot” on the corrector that serves the purpose of a secondary mirror. Generally, Maksutovs have small secondary mirrors with great optics and optimum focal length that makes them outstanding for lunar, planetary, and double-star viewing.
Coming to the building design of the telescope, its unique single fork arm design with an orange color and robust feel combining with a sturdy steel tripod makes it a perfect combination. The small aperture of NexStar 4SE enables you to see more than a couple of hundred deep-sky objects even in a condition of dark skies. It comes with the SkyAlign technology that enables your telescope to get aligned and ready to observe in minutes.
The Celestron NexStar 4SE is fully computerized and motorized. The technology which is being used to drive the telescope has been put through various tests and has been provided with several updates over the years.

How We Chose The Top Catadioptric Telescopes In Our List
After exploring some of the particular products and getting an appropriate idea about what is a catadioptric telescope, it is crucial to know how and what features are needed to be considered to pick the best catadioptric telescopes:
Telescope mount- Being the base of the telescope, a sturdy and adjustable mount is as important as the telescope itself. A telescope that needs additional mount is always less recommended as an additional or a cheap mount could wobble even at the slightest touch and could result in shaky images.
Aperture, focal length, and f-ratio- Aperture forms the basic specs of any telescope, be it refractor, reflector or catadioptric. The detailed and sharp view of the planetary surface depends on these specs along with the magnification levels.
Quality- Along with optimum aperture, focal length, mirror, and lenses, the build quality of the telescope is a fundamental thing. Unless the telescope is built with sturdy support and robust design, its pebbling chances increase during the sky-seeing process. The telescopes listed above are built with premium quality.
Installation and setup- When you are just a beginner in the world of astrography, there is a lot for you to explore and discover. All that can be achieved with the help of a standard telescope but the installation and the setup of the telescope should be easy enough for any beginner. An introduction manual is a must in case you are just starting the process. However, a telescope setup process should be less complex and understandable.
