The MAK 90 telescope is built on the Maksutov optical system, the characteristics of which are excellent image sharpness and lack of chromatic aberration. It consists of a correction plate - meniscus, main mirror and secondary mirror located on the inner part of the meniscus. A design of this kind works well in metropolitan conditions, where it is difficult to observe any nebular objects in bright skies.
This telescope collects about 180 times more light than the human eye at night, providing the ability to observe objects up to nearly 11.4 stellar magnitudes. The size of the mirror is also related to the optical resolution, which in this telescope makes it possible to resolve stars that are more than 1.6 " apart.
The telescope does not come with a mount, but it is possible to mount the tube on a photographic tripod using a suitable connector built into the tube.
