Mars is a challenge for amateur astronomers, but your Sky Watcher 120ED will show some very interesting detail. Fluorite's molecular properties have several distinct advantages. The 120ED. When prominent, the gleaming white Mars’ polar cap is in stark contrast to the redish-orange surface landscape of the rest of the planet. Hence the cost of manufacturing a fluorite lens is quite high compared to a Flint lens element, for instance. Observing with the Sky-Watcher EvoStar 120ED APO Refractor. Read our 101 article or get in touch. My objective for a grab-and go was one that was relatively small and simple to use with optics that would really excel at lunar and planetary views. Enjoy the hunt for double stars like Epsilon Lyrae, the double-double in Lyra, or, always a star party favorite, the beautiful double star Alberio, located in the tail of Cygnus the Swan, is sensational. M92, also in the constellation of Hercules, is a very compact globular with a bright core. Using only the finest fabrication materials available, Sky-Watcher APO refractors are manufactured to painstakingly rigorous, exacting standards of optical and mechanical quality to insure the amateur astronomer peak performance and a great experience each and every time a Sky-Watcher ED-APO is taken into the field. It is not too heavy and easy to balance the scope by moving the OTA within the tube rings. All Sky-Watcher USA EvoStars come with 2-speed backlash-free 2” Crayford-style focusers and quality foam-lined metal carrying cases as standard equipment. Precision 2″ Crayford-style Focuser is Standard. Mars is a challenge for amateur astronomers, but your SW 120ED will show some very interesting detail. Included tube rings, two-speed focuser, ***** rail, case, dust cover.. awesome. The black speckle tube is IMO classy. Great telescope! Chromatic aberration is non-existent, even on "bright" blue stars in long-exposure images. [email protected], © 2020 OPT Telescopes. Named after the famous Danish astronomer Tycho Brahe, it is a spectacular sight with very high-rimmed walls. It is a great object to view with the SW 120ED. These doublet refractors deliver dramatic, coal-black sk... Sky-Watcher EvoStar 80ED APO Refractor: Portable Optical Powerhouse!Due to their unobstructed textbook-like diffraction patterns and exotic optical... SW EvoStar 100ED APO Refractor: When You Demand the Best! Refractors – the Ultimate Imaging Instruments. Pride and Perfection in Optical Manufacturing. The optical tube material is aluminum, powder-coated reflective gloss black with gold fleck accent. Guess I like shiny things. Also saw M80/ M104, M68, M10, M49,... saw all the objects listed in this review here in this scope last night. After many amateur astronomers make the serious plunge, buy a large telescope and enjoy its use for a while, they realize a smaller secondary telescope would be very useful on those nights when you don’t want to drag out your heavy equipment and set it up. Optical focus is achieved by means of a mechanically ultra-smooth, backlash-free, precision 2" Crayford-style rack & pinion focuser-assembly. It is very well built and solid. All Rights Reserved. Powered by Shopify, A Fine Telescope at any Price, Let Alone IT'S Price. Named after the famous Danish astronomer, Tycho Brahe, it is a spectacular sight with very high-rimmed walls. Sky-Watcher ED-APO refractors are the logical choice as an investment in advanced instrumentation for exceptional viewing or photography. To the southeast, the famous crater Theophilus is 65 miles across. Algol, an eclipsing variable star, sometimes called the Winking Eye fluctuates in brightness, and Aldebaran, a beautiful orange giant in the constellation of Taurus, are both delightful sights to view with the SW 120ED. Taks, APs, TECs, SVs, you get my drift. In the eastern corner of Constellation Orion, Rigel, a bright blue double has a blue-green companion that requires excellent optics to see, a worthy subject for the SW 120ED. You will love this scope. On the north end of Mare Nubium, almost on the lunar N-S and E-W center line, you'll find 3 craters grouped together: Arzachel, a young impact crater 60 miles across and 13,000 feet deep, shows a terraced structure and a system of channel-like narrow depressions in its basin called rilles. In this same area can be found craters Maginus and Longomotanus which are also very worthy of exploration. The additional aperture compared to a 100 mm diameter lens provides a dramatic increase in resolution and a heightened sense of seeing lunar and planetary surface phenomenon in seemingly 3-D high-definition. 800-483-6287
SW APO refractors utilize the most modern optical glasses and fabricating techniques to deliver the ultimate in high-fidelity astronomical imaging. One of the southernmost craters, Clavius, is a very large crater 145 miles across. I have been owning for nearly a year the SW Evostar 120ED, a great all-around scope and portable. The views you will experience are so clear and sharp it might just feel like a veritable space-walk. The additional aperture compared to a 100 mm diameter lens provides a dramatic increase in resolution and a heighten sense of seeing lunar and planetary surface phenomenon in seemingly 3D high-definition. chromatic aberration) normally present in 2-element achromatic lens designs which utilize standard crown and flint glasses. Refractors are coveted for their superb contrast, high-definition and coal-black sky background that make stars appear like diamonds embedded in black velvet. Surprisingly both eyepieces (20 and 5mm) are darn fine for included eyepieces. Very straight and sharp lines with only a *hint* of curvature. Start Chat
The finder is 'serviceable'. I replaced it with a Moonlite focuser, and the result is a first-rate instrument for visual and photographic applications. The Sky-Watcher APO optical tubes come with attachment hardware that allows them to be securely fastened to compatible mounts. Nirgal Vallis is a channel 600 miles long that responds well to the razor sharp contrast provided by the SW 120ED.
