This Sky-Watcher 120 mm Evostar APO telescope is a doublet ED-Apochromatic refractor that provides the finest images obtainable in this design and price class. This doublet refractor delivers dramatic, jet-black skies and faithful, contrast-rich views of planetary and deep-space phenomenon that are second to none. This scope is your ticket to exploring the wonders of the celestial sphere which you have been waiting to see.
Due to their unobstructed aperture and textbook-like diffraction patterns and exotic optical properties, the ED-APO produces the sharpest, highest quality imaging obtainable from any telescope optical design. These breathtaking sharp, contrasty celestial views are coveted by experienced amateur astronomers. A 120 mm refractor will provide a crisp, well-defined image which is inherently superior to even a larger reflector; this is due to its objective aperture not being obstructed by any other optics.
Fortunate indeed is the amateur astronomer with a Skywatcher ED-APO 120 mm Evostar refractor on a clear night with transparent skies and a stable atmosphere. The Sky-Watcher ED-APO 120 mm is a moderate magnification telescope offering bright, beautiful views of sky. It is well suited for astronomical observation of prominent nebulae, star clusters and galaxies from a dark-sky location, or can be used as an astrograph for sky photography. As an astrograph, the SW EvoStar 120 ED APO performs superbly delivering crisp, high-fidelity imaging of planetary, lunar and aperture appropriate deep-space phenomenon. For visual observing work on most of the popular celestial objects, this scope will never disappoint you!
As an astrograph, the EvoStar 120 ED-APO delivers superb performance, imaging a wide spectrum of astronomical phenomenon. Sky-Watcher ED-APO refractors will provide exceptional viewing or photography. ED-APO optical design assures virtual elimination of residual “false color” (chromatic aberration) normally present in 2-element achromatic optics. Sky-Watcher APO refractors utilize the finest extra-low dispersion (ED) glass available, FPL-53. This results in the best color correction for an ED doublet objective for a telescope. Schott Glass is used by Sky-Watcher for the front crown glass element and also for the ED 2 lens element because Schott is the recognized world leader in glass utilized for precision optical lens systems. 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 rigorous, exacting standards of optical and mechanical quality to insure the amateur astronomer peak performance.
The objective lens cell is light-baffled to reject stray, unfocused light. The draw tube is likewise baffled to insure optimum contrast. The tube interior is flat blackened to help prevent unfocused internal light reflections from reaching the focal plane. The optical tube material is aluminum, powder-coated reflective gloss black with gold fleck accent. The front and back cells are cast-aluminum painted white or black. The Sky-Watcher APO optical tubes come with attachment hardware that allows them to be securely fastened to compatible mounts with quick-release tube rings. All Sky-Watcher USA EvoStar's come with 2-speed backlash-free 2” Crayford-type focusers and a quality foam-lined metal carrying case, as standard equipment.
This scope includes an 8×50 Right-Angle Erect-Image Finder Scope and a 2" Dielectric type Star Diagonal, and two Eyepieces.
