Celestron Mini Maks bring portability and versatility; the Maksutov optical design is recognized for being compact, easy to use, and applicable for both terrestrial (land) and astronomical use.
C70 Mini Mak is a small but powerful spotting scope that includes a tabletop tripod which has built-in slow motion controls, a built-in zoom eyepiece capable of 75x magnification, and soft carrying case.
Maksutov-Cassegrain Optical Design
The MAK is a catadioptric spotting scope, 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 the 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 spotting scope does not require frequent collimation. Also, the secondary spot is significantly smaller, giving the MAK its signature high-contrast views.
One important thing to note about Maksutov-Cassegrain spotting scope is that the larger, heavier Maksutov corrector plate takes longer to cool down and adjust to ambient air temperature.
