상품특징
EXPERTLY MATCHED OPTICS: The Skymax series of Maksutov-Cassegrain optical tubes features matched primary and secondary mirrors with an expertly coated corrector plate that delivers contrast-rich views with charcoal-black skies.94% REFLECTIVITY MIRROR COATINGS: Sky-Watcher Maksutov-Cassegrains feature a borosilicate primary mirror with an aluminum coating and a quartz overcoat, producing a 94% reflectivity rating for outstanding light transmission.CONVENIENT MOUNTING PLATE: Using a ¼-20 tripod thread, the 90mm Maksutov allows users to mount to most photographic tripods without the need for any adapters or added accessories.FULLY BAFFLED TUBE: Utilizing a fully-baffled tube, Sky-Watcher Maksutovs prevent stray light from interfering with your viewing experience.EVERYTHING YOU NEED: The 90mm Skymax Maksutov-Cassegrain telescope comes equipped with everything you need to get started, including: 10mm and 25mm 1.25-inch eyepieces, a red-dot finder, 90-degree star diagonal, and a padded carrying bag.
상품설명
Sky-Watcher’s premiere line of Maksutov-Cassegrain telescopes create a perfect blend of aperture and lightweight portability. This telescope design has a reputation for sharp, high-contrast views, ideal for planetary observation. Maksutov-Cassegrain telescopes serve as an alternative to Schmidt-Cassegrains and Newtonians, and offer astronomers a large visual aperture, high contrast, and long focal length in a compact package. Maksutov’s deliver better planetary detail than other telescopes due to a focal length that’s 5-7 times longer, increasing overall magnification. Maksutov-Cassegrains also use a meniscus-shaped corrector plate, eliminating any spherical aberration caused by the primary mirror, guaranteeing a flat visual plane across the entire field of view. Our Maksutov series telescopes deliver refractor-like views and superior contrast while allowing for larger apertures at a fraction of the cost. Our Maksutov series features a borosilicate primary mirror with an aluminum coating and a quartz overcoat, producing 94% reflectivity. The corrector plate utilizes our proprietary Metallic High -Transmission Coatings (MHTC ), giving visual astronomers professional-grade optics, creating a unique viewing experience.In addition to the visual benefits of Sky-Watcher Maksutovs, these serve as excellent optical tubes for imaging planetary, lunar or solar (with use of a solar filter). For astronomers looking to start in astrophotography, the Sky-Watcher Maksutovs deliver exceptionally long focal lengths, necessary for imaging planetary detail. This provides an increased image scale, forgoing the need of a barlow lens or other accessories that may increase exposure times.As customary with all Sky-Watcher products, the Maksutov series includes a bundle of accessories, including: 10mm and 25mm 1.25-inch eyepieces, 1.25-inch adapter, 90-degree star diagonal,and a padded carrying bag.
