The Sky-Watcher Pro SW 100ED APO 100mm ED Refractor Telescope is manufactured using only the finest fabrication materials available for 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. Turning the telescope to the first quarter Moon, the Apennine Mountains snap into focus revealing a cornucopia of jagged mountain ridges, canyons and numerous small craters in razor-sharp detail.
Not far removed, reaching skyward the crater wall of Archimedes pops into view in bold relief against the smooth flatlands that transverse the distance between it and the Apennine Mountains. This is lunar observing at its best - HD style. The gas giant Jupiter displays its swirling equatorial bands in high-definition with festoons and tonality within the bands. The great spot is clearly visible, discreetly contrasted from the surrounding Jovian landscape. Saturn's storied surface phenomenon is simply stunning. Hunt down double stars like Epsilon Lyrae, the "double-double" in Lyra. A 100mm refractor will provide a crisp well defined image superior to even a larger reflector.
Always a star-party favorite, Alberio located in the tail of Cygnus never fails to please as it is a beautiful double. Alberio appears like a gold sparkler and its companion looks blue-green. It is a perfect refractor object. Compact globular star clusters lend themselves well to a refractor. Located outside our galaxy the globular M2 will probably resolve more stars in a 4" refractor than a 6" reflector. M4, M10 and many other globular cluster can be seen well with a 100mm refractor. M13, the fantastic globular in Hercules is a stunning sight in a 100mm refractor.
The bright central cores of prominent nebulae can be seen and the brightest stars can be resolved. As an astrograph, the SW PRO 120ED APO performs superbly delivering crisp, high-fidelity imaging of planetary, lunar and aperture appropriate deep-space phenomenon. 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 refractor provides the finest images obtainable-bar none-in their design class. Sky-Watcher ED apochromatic refractor delivers dramatic coal-back skies and faithful, contrast-rich views of planetary and deep-space phenomenon that are second to none. Sky-Watcher ED-APO refractor is the logical choice as an investment in advanced instrumentation for exceptional viewing or photography.
