Webb4 mars 2024 · The Schmidt-Cassegrain (SCT) optical system uses a combination of mirrors and lenses and is referred to as a compound or catadioptric telescope. This unique design offers large-diameter optics while maintaining very short tube lengths, making themextremely portable. WebbThe Maksutov corrector plate is a meniscus corrector with a highly curved spherical lens. This corrector lens corrects a coma found in all reflecting telescopes while also correcting spherical aberration. The corrector is much thicker compared to the SCT corrector, so that’s why MAKs are usually made with a small aperture.
