Orion Premium 190mm f/5.3 Mak-Newt Astrograph Telescope
Description
The Orion Premium 190mm Maksutov-Newtonian Astrograph Telescope Astrograph is an ideal instrument for astrophotographic pursuits, but it can also be used for stunning visual observations on those nights when you'd rather stargaze insteadof capturing images. This Premium "Mak-Newt" Astrograph delivers crisply detailed and colorful images of deep-sky phenomena with its flat-field, coma-suppressed optics. The telescope's all-machined dual-speed 2" Crayford-style focuser with 11:1 finefocus control provides smooth motion. The focuser includes 2" and 1.25" compression ring adapters for scratch-free insertion of eyepieces and other accessories. A T-thread adapter is included for direct attachment of a camera body (may requireappropriate T-ring, sold separately). Two included tube rings and a narrow dovetail mounting bar are included for easy attachment of the 22 lb. telescope tube to appropriate mounts and tripods.The 190mm Maksutov-Newtonian Astrograph optics providetremendous resolution with its optically fast f/5.3 design. The impressive 7.5" aperture ensures plenty of light-gathering ability to capture superb images of even the faintest of deep-sky gems. The high-grade, low-expansion primary mirror with enhancedreflectivity coatings and the fully multi-coated BK7 meniscus lens render truly spectacular images, with pinpoint stars across the entire field of view. The 37.5"-long metal tube contains five internal baffles for exceptional contrast.The secondarymirror diameter of 64mm provides a very large illuminated field to take full advantage of larger CCD sensors. The 100% fully illuminated field diameter of over 22mm produces brighter images with less vignetting compared to other telescope designs.OurPremium Mak-Newt Astrograph performs just as admirably visually. The included focuser extension adapter allows visual astronomers to enjoy the sharp, high-contrast views that only a well-made instrument can deliver.
