Maksutov-Cassegrain telescopes are a type of compound telescope that combines features of both the Maksutov and Cassegrain designs. They use a spherical primary mirror and a corrector lens at the front, which helps to reduce optical aberrations. This design allows for a compact and portable telescope that provides clear images of celestial objects. These telescopes are popular among amateur astronomers for their versatility and ease of use. They are suitable for both planetary and deep-sky observations, making them a great choice for those looking to explore the night sky. Their sturdy construction also makes them durable for outdoor use.
