Construction: Maksutiv-Newton catadioptrical reflector
The MN61 features a catadioptric Maksutov-Newton type design with two mirrors and a full aperture meniscus corrector element.
The front of the MN61 shows the small secondary mirror causing a central obstruction of only 19,7% and the coating of the meniscus lens.
The helical focusser of the MN61 needs some rework to be usable. The scope is also available with a crayford style focusser.
