Maksutov-Cassegrain Optical Design

The Mak design combines lenses and mirrors to deliver images that are:

• Bright and sharp across the field of view

• Virtually free from chromatic aberration

• High contrast, thanks to the smaller secondary spot

Unlike other designs, the C70 Mini Mak requires minimal collimation, making it easier to maintain. Its only consideration is a slightly longer cool-down time due to the larger corrector plate.

Compact and Versatile

With a focal length of 750mm (f/10.7) and zoom magnification between 25x and 75x, the C70 Mini Mak is perfect for:

• Birdwatching and wildlife observation

• Scenic and long-distance terrestrial views

• Casual stargazing, including the Moon and planets

The included tabletop tripod with slow motion controls makes tracking objects smooth and intuitive, while the soft nylon case ensures safe transport anywhere.
