Sky-Watcher EXPLORER 190mm 7.5" MAKSUTOV NEWTONIAN DS Telescope OTA #10205 AN ASTROPHOTOGRAPHERS DREAM TELESCOPE!! The exciting new Maksutov-Newtonian from Sky-Watcher is just what astro-photographers and serious visual observers have been looking for. The Maksutov-Newtonian design combines the best features from the Newtonian Reflector and the Maksutov-Cassegrain to create a telescope design that provides truly stunning image quality, providing high-contrast, perfectly flat images, free from false colour. The Maksutov-Newtonian design provides large aperture Apochromatic performance, with exceptional field correction, in a compact, amazingly affordable package. Stars appear as classic pinpoints across the entire field. Perfectly optimised for modern DSLR cameras. The premium optics are housed in a robust rolled-steel tube for excellent mechanical integrity. Five internal knife-edge baffles are included to eliminate internal reflections and further enhance contrast. The Primary Mirror is made of low thermal expansion Pyrex® glass for a significantly reduced cool-down time. Compared to a similarly sized Schmidt-Newtonian, the Maksutov-Newtonian yields a sharper and more contrasty image. Naturally, the Maksutov-Newtonian is an excellent visual performer too!!

Most reflectors today usually have a coat of aluminium as the mirror surface and then an overcoat of silicon monoxide or silicon dioxide to protect it. Silicon dioxide produces a much more durable coat than silicon monoxide but requires specialized equipment to apply it and is therefore more expensive. Protection is needed, because in most reflectors, the mirror is open to the elements and deterioration of the reflective layer reduces the resolution of the telescope. ALL Sky-Watcher reflectors are Multi-Coated with Silicon Dioxide as standard for Optimum Durability and Long Term Performance.
