SkyWatcher 190/1000 Maksutov-Newton telescope

Maksutov-Newton telescopes are a real novelty in the world of binoculars. The catadioptric optics system combines the advantages of the Maksutov-Cassegrain and Newtonian telescopes: bright optics, large field of view, and high contrast imaging without coma defects. Recommended primarily for astrophotographers or demanding visual observers. The large diameter of 190 mm and excellent imaging make it extremely versatile.

The SkyWatcher 190/1000 Makasutov-Newton is quite bright (f/5.25), yet the imaging is flat and spot-on even at the edge of the field of view. This also makes it ideal for astrophotography with DSLRs. Its excellent imaging is mainly due to the very high precision of the main mirror and correction lens (meniscus), which are bounded by spherical surfaces. The 5 knife-edge aperture inside the tube minimises internal reflections, resulting in excellent contrast. In addition, the central flare caused by the secondary mirror is also small and, unlike Newtonian systems, there is no need for secondary mirror legs. As a result, the Makasutov-Newton telescopes are comparable in performance to apochromats, while their price is well below them.

Optical elements are made of small thermal expansion Schott glass materials, with optical coatings on all surfaces. Premium solutions also include a precision 2" 1:10 microfocus Crayford focuser.
