  • 700 Maksutov-Cassegrain telescope with f/15 focal ratio provides high contrast views of the planets and lunar landscapes, perfect for serious planetary imagers and visual observers.
  • Celestron’s premium StarBright XLT coatings ensure maximum light transmission.
  •  CGEM mount and provides a sturdy and rigid platform.
  • The drive system, consisting of low cog DC Servo motors with integrated optical encoders, steel worm gears supported by precision sealed bearings, and brass worm wheels, ensures smooth and accurate slewing and tracking.

The 700 Maksutov-Cassegrain CGEM II telescope (CGEM II 700 Mak) is a specialized instrument designed for detailed, high contrast views of smaller celestial objects like the planets. Maks are also well suited to hunting smaller, fainter, deep sky objects such as globular clusters and planetary nebulae.  Astronomers located in urban areas will appreciate the Mak’s ability to bring out more contrast in celestial objects.

 Maksutov-Cassegrain Optical Design

 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.

CGEM II Mount & Tripod

 

Designed with imaging in mind, the CGEM II motor drive system accurately tracks during an exposure.

To track objects in the night sky, the mount must first be polar-aligned. Celestron makes this process easier than ever with the innovative All-Star Polar Alignment procedure. No extra equipment, such as a polar finder scope, is required.

StarBright XLT Technology

StarBright XLT is Celestron’s revolutionary optical coating system that outperforms any other coating in the commercial telescope market.

Solar Warning
  • Never look directly at the Sun with the naked eye or with an optic (unless you have the proper solar filter). Permanent and irreversible eye damage may result.
  • Never use your optic to project an image of the Sun onto any surface. Internal heat build-up can damage the optic and any accessories attached to it.
  • Never leave your optic unsupervised. Make sure an adult who is familiar with the correct operating procedures is with your optic at all times, especially when children are present.
