About Celestron Maksutov-Cassegrain Telescopes
Celestron’s Maksutov-Cassegrain telescopes are similar to Schmidt-Cassegrain models in regards to ease, durability, versatility, and minimal maintenance, but trade smaller fields of view for better resolution in planetary observation.
The Maksutov-Cassegrain is similar to the Schmidt-Cassegrain with essentially the same advantages and disadvantages. It uses a thick meniscus correcting lens with a strong curvature and a secondary mirror that is usually an aluminized spot on the corrector. The Maksutov secondary mirror is typically smaller than the Schmidt’s which gives it slightly better resolution for planetary observing.
Advantages of Maksutov-Cassegrain Compared to Schmidt-Cassegrain
- Smaller secondary obstruction results in a slight increase in planetary detail and contrast
- Less expensive to manufacture
- Longer focal lengths resulting in higher magnifications for planetary viewing
Disadvantages of Maksutov-Cassegrain Compared to Schmidt-Cassegrain
- Slightly heavier because of the thick meniscus correcting lens
- Increased time to reach thermal stability in larger apertures over 90 mm
- Longer focal lengths resulting in smaller field of view
