• The 700 Maksutov-Cassegrain CGX telescope (CGX 700 Mak) is a specialized instrument designed for detailed, high contrast views of smaller celestial objects like the planets. With the Maksutov-Cassegrain optical tube and sturdy equatorial mount and tripod, this kit will provide unparalleled views of the planets and up-close views of the lunar surface, including craters and maria. Maks is also well suited for capturing smaller, fainter, deep-sky objects such as globular clusters and planetary nebulae. Astronomers located in urban settings will appreciate the Mak's ability to bring out more contrast in celestial objects. Transporting the entire system to a dark site is not a problem either. The optical tube, mount head, tripod, counterweight bar, and counterweight all disassemble, with no tools required, into separate manageable pieces.

  Features of the 700 Mak CGX Telescope

  Maksutov-Cassegrain Optical Design 

  The Mak is a catadioptric telescope, which means the optical design includes both a lens and a mirror. The light coming through a Mak passes through the corrector lens to the primary mirror and back to a spherical secondary mirror before it hits your eyepiece. Images are bright, sharp, and virtually free of chromatic aberration.

   

  

  The Maksutov-Cassegrain's optical design offers several unique benefits. Instead of a secondary mirror, the Mak features a "secondary spot" of reflective coating applied directly to the inside of the corrector plate. Because of this, the telescope does not require frequent collimation like a Schmidt-Cassegrain. This secondary spot is significantly smaller than a traditional Schmidt-Cassegrain secondary mirror, allowing you to capture the signature high-contrast views offered by the Maksutov-Cassegrain design.
  
  An important thing to note about Maksutov-Cassegrain telescopes when compared to a Schmidt-Cassegrain of the same aperture; the larger, heavier Maksutov corrector plate will take longer to cool down and adjust to ambient air temperatures.
