Named after the famous Danish astronomer, Tycho Brahe, it is a spectacular sight with very high-rimmed walls. But he said it would not surprise him to find it was at LEAST 1/6th wave and maybe 1/8th or more. We will be glad to help. 800-483-6287 The Grand Canyon of Mars, Valles Mariners, dwarfs that of our Earth's Grand Canyon, but it still requires superb optics to view, even though it is 150 miles wide and 4 miles deep. North of Tycho appearing brightly in a basin is the famous Rupes Rect (the Straight Wall), an 800 foot mountain that is a "must see" for amateur astronomers. First, it has superior dispersion characteristics compared to pure silica-based glass. This focuser offers 2-speed fine and ultra-fine focusing adjustments. The objective lens cell is light-baffled to reject stray, unfocused light. Sky-Watcher Evostar 150ED DS-Pro - A busted flush? Sky-Watcher ED-APOs – the Ultimate Refractors. Sky-Watcher ED apochromatic refractors deliver dramatic coal-back skies and faithful, contrast-rich views of planetary and deep-space phenomenon that are second to none. I have a StellarVue in there. Get high enough in altitude, and use a well corrected EP and I just don't see it. Olympus Mons, a volcanic crater 375 miles across and 16 miles high, is just one of the quests your capable SW120ED can tackle. Nirgal Vallis is a channel 600 miles long that responds well to the razor sharp contrast provided by the SW 120ED. The gas giant Jupiter displays its swirling equatorial bands in high-definition with festoons and tonality within the bands. There is no diffraction pattern interference caused by a diagonal mirror or secondary mirror being suspended in the optical path (central obstruction) as is the case with reflectors. Read our 101 article or get in touch. Each air-to-glass lens surface has exotic anti-reflection metallic coatings applied to ensure optimum light through-put. Powered by Shopify, A Fine Telescope at any Price, Let Alone IT'S Price. I would suggest to any serious amateur astronomer that appreciates a quality refractor and who doesn't have a ton of money to spend to seriously consider investing in this scope - I'm glad I did. The proprietary Sky-Watcher “Metallic High-Transmission Coatings” (MHC) are the finest photon anti-rejection coatings in their class. It is located south of Tycho. Every lens element is individually inspected for purity and absence of striae and other image-degrading imperfections. Sky-Watcher is a leader in the design and manufacturer of ED-APO systems. It functions as a high-index lens with very low dispersion. The front and back cells are cast-aluminum painted white, or black. Many advanced amateur astronomers feel the ED-APO experience is astronomy’s richest. M5 is a worthy object for viewing. To the southeast, the famous crater Theophilus is 65 miles across. Couldn't decide between Evostar 120 vs 150 and just didn't know how the quality compares to other brands, but I found this scope is completely awesome (and i've owned dozens of scopes) and no need to spend money on others costing way more I use mine for visual only. Your Sky-Watcher EvoStar 120ED … Please Log in to save it permanently. The Sky-Watcher APO optical tubes come with attachment hardware that allows them to be securely fastened to compatible mounts. You will love this scope. These objects will stand out in bold relief contrasted against a very dark velvet-black sky background. I enjoyed some nice views of Jupiter, the moon and some DSOs I'm having my attention on slightly bigger aperture and still portable refractor these days such as the SW Startravel 150 F/5. Every lens is pitched polished to exacting standards of optical fabrication and performance by highly skilled opticians utilizing state-of-the-art methodology and rigidly controlled optical testing procedures. A *HINT*. Only one complaint, Since I bought it, the curse of the bad skies has followed me here in California, only about 10 decent nights of viewing from December 15th until April 17th. The only false color I see is atmospheric or eyepiece caused. With regular observation, you will be able to follow storms and disturbances cross the planet in the southern equatorial band. The Grand Canyon of Mars, Valles Mariners, dwarfs that of our Earth's Grand Canyon, but it still requires superb optics to view, even though it is 150 miles wide and 4 miles deep. The superb capabilities of the Sky-Watcher 120ED provide performance on a par with a reflector of perhaps up to 7" in diameter on lunar, planetary, double-stars, globular star clusters, even the brighter nebulae. While Schott glass is only used in selected models, all other models utilize top-quality, Grade-A glass from perhaps less famous but, nonetheless, highly respected, high-quality glass manufacturers. And has done this test and DPAC tests on all scopes he owns. 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. The crater has massive walls and the basin is 14,000 feet deep. To the southeast, the famous crater Theophilus is 65 miles across. Figure 1. He would not specifically pronounce exactly how good without using a DPAC. I like the way it looks. I now own a Sky-Watcher 80MM ED 3.1 APO for grab and go....And the the Celestron Nexstar.....Well.. Hence the cost of manufacturing a fluorite lens is quite high compared to a Flint lens element, for instance. It is not too heavy and easy to balance the scope by moving the OTA within the tube rings. The views you will experience are so clear and sharp it might just feel like a veritable space-walk. chromatic aberration) normally present in 2-element achromatic lens designs which utilize standard crown and flint glasses. Surprisingly both eyepieces (20 and 5mm) are darn fine for included eyepieces. Every lens is pitched polished to exacting standards of optical fabrication and performance by highly skilled opticians utilizing state-of-the-art methodology and rigidly controlled optical testing procedures. The draw tube is likewise baffled to insure optimum contrast. Chromatic aberration is non-existent, even on "bright" blue stars in long-exposure images. Nirgal Vallis is a channel 600 miles long that responds well to the razor sharp contrast provided by the SW 120ED. Bob in Oakland, Calif. Included Components for Selected Models. As an astrograph, the SW EvoStar 120ED APO performs superbly delivering crisp, high-fidelity imaging of planetary, lunar and aperture appropriate deep-space phenomenon.
