BK MAK90 OTA TELESCOPE

Maksutov-Cassegrains are similar to the Schmidt-Cassegrains. They also have a corrector plate to remove spherical aberration, but they use a thick, meniscus lens instead of a Schmidt lens. Advantages of Maksutov-Cassegrains Very compact and portable;Short physical length telescopes with a long focal length good for planetary viewing;Sharp optics;Good for revealing Lunar and planetary details at high power and excellent for terrestrial applications Very compact and portable;Short physical length telescopes with a long focal length good for planetary viewing;Sharp optics;Good for revealing Lunar and planetary details at high power and excellent for terrestrial applications
