Product Details

  • The Sky-Watcher 190 mm Maksutov-Newtonian Telescope is a large aperture instrument with impressive performance, but it is still relatively portable. This scope could be just what you need if you want a wider field of view than is possible with a Maksutov-Cassegrain or a classic refractor. This telescope has a focal ratio of f/5.3 and thus will provide a wider field than a conventional Maksutov. The Mak-Newtonian design, with its fully multi-coated Pyrex mirrors, provides large aperture apochromatic performance with exceptional field correction in a compact, affordable package. Compared to a similarly sized Schmidt-Newtonian, the Mak-Newtonian yields a sharper image with more contrast.

    The 190 mm or 7.4" aperture of the Sky-Watcher Maksutov-Newtonian offers you great light gathering capability. Extra aperture translates to brighter and sharper images for you. The OTA is supported by two hinged metal tube rings attached to a black V-style dovetail plate. With its 2" dual-speed 10:1 Crayford focuser, and 8x50 optical finderscope, you are ready to begin on your journey of discovery. Just mount the OTA to your favorite telescope mount via the cradle rings and Vixen-style dovetail. The exciting Maksutov-Newtonian Telescope from Sky-Watcher is just what astrophotographers and serious visual observers have been looking for.

    Fantastic optics

    First thing to mention is that this is quiet a heavy bit of kit with the corrector plate, coming in at around 30lbs/13kg - so make sure your mount is up to the job. I was shocked at how pinpoint the stars were throughout the entire field of view, the corrector plate does a great job of producing a flat field that requires absolutely no need for additional correctors. The dovetail plate is a fluorescent green cast iron ***** style plate, not the black D-style plate as shown in the photos. This is something which I might be upgrading to, even though the ***** is pretty stable, it ruins the look of the scope. This is a personal taste thing, and wouldn't put a dent in the 5 star rating for me. The collimation bolts are a little finicky, and take some getting used to - more so than other newts/maks I've had before. The Crayford focuser is no Feather-Touch steup, but it certainly gets the job done, so no complaints there. As a long term Maksutov user, this is a great upgrade from my 6" Mak.
