Sky-Watcher Evostar PRO 120 mm f/7.5 ED APO OTA

SkyWatcher ED APO refractors are able to generate sharp images superior in quality to those achieveable through any telescope optical design due to their nearly flawless unobstructed diffraction patterns and novel optical properties. The resulting spectacular celestial views are the kind of pristine views envied by experienced amateur astronomers.

Observing with the Sky-Watcher EvoStar PRO 120ED APO Refractor:

Touring the Moon: The rugged Southern Highlands of the lunar surface are rich in craters. To the southeast, the famous crater Theophilus is 65 miles across. The raised triple-peaked central area is striking to observe in your Sky-Watcher 120ED. The crater has massive walls and a 14,000 foot deep basin. One of the southernmost craters, Clavius, is a very large crater that measures 145 miles across. It is located south of Tycho. In this same area can be found craters Maginus and Longomotanus which are also worthy of exploration. To the north, the young crater Tycho dominates the southern lunar landscape. Named after the famous Danish astronomer Tycho Brahe, it is a spectacular sight with very high-rimmed walls. Your SW 120ED will provide an impressive view. 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. Your Sky-Watcher EvoStar 120ED will show it clearly and sharply the way you want to see it. On the north end of Mare Nubium, almost on the lunar North-South and East-West center line, three craters grouped together can be found: Arzachel, a young impact crater 60 miles across and 13,000 feet deep that shows a terraced structure and a system of channel-like narrow depressions in its basin called "rilles". Nearby are Alphonsus, a 70 mile wide crater, and Ptolemaus a prominent ancient crater 90 miles across with a heavily worn dark interior. The Earth's Moon offers a treasure trove of fascinating detail to explore with your Sky-Watcher EvoStar PRO 120 mm ED APO Refractor.

Planets are Spectacular: The inner solar system presents the colorful rusty-red planet Mars. Typicall a challenge for amateur astronomers, your EvoStar PRO 120ED will show some intriguing details. Olympus Mons, a volcanic crater 375 miles across and 16 miles high, is just one of the quests your SW 120ED is capable of handling. Nirgal Vallis is a channel 600 miles long that responds well to the razor sharp contrast provided by the SkyWatcher 120ED. 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's 150 miles wide and 4 miles deep. When prominent, the gleaming white Mars polar cap is in stark contrast to the reddish-orange surface landscape of the rest of the planet. The 120 mm EvoStar Pro ED APO Refractor will show you this detail like you want to see it. The gas giant Jupiter displays its swirling equatorial bands in high-definition with festoons, and tonality within the bands. With regular observation you will be able to follow storms and disturbances across the planet in the southern equatorial band. Saturn's storied surface phenomenon is simply stunning.

Wonders of Deep-Space: Beyond the solar-system, the SW 120ED lets you hunt down double stars like Epsilon Lyrae, the "double-double" in Lyra. A 120 mm ED-APO refractor provides a crisp, well-defined image on par with an up to a 7" reflector. Always a star-party favorite, the beautiful double Alberio located in the tail of Cygnus is sensational. Alberio appears like a gold sparkler and its companion looks like a blue-green sparkler. Algol, an eclipsing variable star, sometimes called the "winking eye" fluctuates in brightness and is a suitable subject for the Sky-Watcher 120ED. Aldebaran, a beautiful orange giant in Constellation Taurus is also a delightful sight. In the eastern corner of Constellation Orion, Rigel, a bright blue double has a blue-green companion that requires excellent optics to see, is another worthy subject. Tight globular star clusters like M13 in Constellation Hercules appear like a beehive of crisp stellar pin points circling the central core, star upon thousands of stars.

As an astrograph, the Sky-Watcher EvoStar PRO 100ED provides outstanding performance imaging an abundance of celestial wonders.

Refractors, the Ultimate Imaging Instruments: In a given aperture size, refractors will always exhibit sharper images than other optical designs because the refractor concentrates more light into the central airy-disk and first diffraction rings. 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.

Sky-Watcher ED-APO the Ultimate Refractors:

Virtually Eliminates Residual Chromatic Aberration: For their design class, ED-APO refractors from Sky-Watcher offer the finest obtainable images. If you covet the ultimate in pristine, virtually flawless astronomical imaging, you've finally found what you're looking for! With Sky-Watcher ED apochromatic refractors, you'll experience breathtaking reliably high contrast views that have no equal of planetary and deep-space objects against pitch black skies. As an investment in advanced instrumentation for exceptional viewing or astrophotography, Sky-Watcher ED-APO refractors are the logical choice.

Schott Glass Used for Front Crown Element and ED 2 Lens Element: The EvoStar Pro 120ED benefits from the incorporation of Schott glass being utilized for the objective's positive front Crown element. For glass used for precision optical lens systems, including medical instrumentation, as well as well-known camera lenses, Schott is recognized as the world leader. Although Schott glass is only included in certain models, all other telescopes use high quality, Grade A glass from highly respected, if less famous, glass manufacturers.

Pride and Perfection in Optical Manufacturing: To ensure purity and absence of striae and other image corrupting deficiencies, all lens elements are separately inspected. Highly skilled opticians use advanced techniques and tightly controlled optical testing procedures to pitch polish each lens to exacting standards of optical fabrication and performance. This enables high quality, diffraction-limited optics that perform to the theoretical confines of their specific aperture sizes. All lenses are evenly air-spaced in their cell housings.

Sky-Watcher offers one of the most extensive lines of ED-APOCHROMATIC refractors in the world: 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. We know the amateur astronomer has very high expectations regarding astronomical equipment purchases. Sky-Watcher has been delivering consistent satisfaction for over a decade.

Metallic High-Transmission Lens Coatings: All air-to-glass lens surfaces features exceptional anti-reflection metallic coatings to ensure ideal light throughput. Sky-Watcher's proprietary Metallica High-Transmission Coatings (MHC) are the best available anti-rejection coatings in their class.

Light-Baffled Optical Systems

The objective lens cell features light baffles to eliminate excess, unfocused light. Likewise, the drawtube is baffled for supreme contrast. The interior of the optical tube is flat blackened to keep unfocused internal light reflections from arriving at the focal plane.

Precision 2" Crayford-style Focuser is Standard

Optical focus is obtained via a mechanically ultra-smooth precision 2" Crayford-style focuser with no backlash. Includes 1.25" adapter. This M56x1 threaded focuser provides two speed for fine as well as ultra-fine focusing adjustments.

Tube Materials:

Optical tube features aluminum construction and powder-coated reflective gloss black with gold fleck accents. The front and back cells are cast-aluminum and painted either white or black.

Telescope Tube Attachment Hardware:

Sky-Watcher APO optical tubes come with attachment hardware that allows them to be securely fastened to the SkyWatcher EQ5P mount. The quick-release tube rings provided with Sky-Watcher ED-APO models 80ED 100ED and 120ED are cast-aluminum, painted white.

Included Components for Selected Models:

Sky-Watcher EvoStar Pro ED-APO telescope models come with an 8x50 right angle viewfinder and bracket, 2" dielectric diagonal, a pair of 1.25" eyepieces with long eye relief (25 mm and 5 mm), 1.25" focuser adapter, tube ring attachment hardware for mounting to the Sky-Watcher EQ5PRO Mount (or other compatible mount), and a foam-lined aluminum carry and storage case for both the optical tube and accessories.
