A catadioptric telescope uses both the reflection and the refraction to produce an image. The Schmidt-Cassegrain telescope (SCT), the Maksutov telescope or the Dall-Kirkham are all catadioptric telescopes. Usually with a long focal length, you'll be able to get a large aperture but compact telescope which excels for high resolution observing or imaging. The Moon, the planets, galaxies, nebulas, those are all objects you can expect to observe or image in a dark sky with a catadioptric telescope. Let us help you find the perfect catadioptric telescope to get started in your celestial journey!
