Celestron MAK 90mm Angled Spotting Scope for Long Range Viewing - 39x Magnification

The Maksutov optical design is widely appreciated for its portability, ease of use, and diverse applications, making it a prime selection for both terrestrial and astronomical observations. The C90 Maksutov features superb optics that deliver exceptionally sharp images across a broad field of view.

Maksutov-Cassegrain Optical Design

As a catadioptric spotting scope, the MAK incorporates both a lens and a mirror within its optical design. Light enters the MAK through a corrector lens, progresses to the primary mirror, reflects back to a spherical secondary mirror, and ultimately reaches the eyepiece. This intricate path results in images that are bright, sharp, and nearly free from chromatic aberration.

A standout aspect of the Maksutov-Cassegrain design is its unique secondary feature. Instead of employing a conventional secondary mirror, the MAK uses a reflective coating applied as a “secondary spot” on the interior of the corrector plate. This innovation allows the spotting scope to maintain its performance without requiring frequent collimation. Moreover, the smaller size of the secondary spot enhances the contrast of views, contributing to the MAK's renowned image quality.

It is important to consider, however, that the larger and heavier corrector plate in the Maksutov design does take more time to reach thermal equilibrium with the surrounding air temperature.

The Celestron 52268 90mm Maksutov Spotting Scope combines excellent high-power optics with compactness and affordability. The package is thoughtfully equipped with a soft carrying case styled like a backpack, an 8x21 erect image finder scope, a 1.25-inch correct image 45° prism diagonal, and a fully coated 32mm Plossl eyepiece, facilitating a magnification of 39X.
