The Sky Watcher 254N EQ5 PRO Newtonian Reflector Telescope S11650 offers amazing light gathering capability combined with portability. The Sky Watcher Telescope has the potential to capture extraordinary fine detail of the solar system and of other deep-space objects. Its large 254mm aperture will allow the observer to capture faint galaxies, nebulae, and star clusters the way they should be seen. Sky Watcher's 254N Eq5 PRO Newtonian Telescope will hit the sweet spot for many serious amateurs out there searching for large aperture, a reasonable cost and GO-TO capability.
The additional detail that can be seen with this Sky Watcher Newtonian Reflector Telescope is truly impressive. Its larger light gathering ability pays big dividends in brightness and increased resolution, especially with respect to faint magnitude objects beyond the visual limit of an 8 inch (203mm) telescope.
Objects that can be seen with an 8" telescope will look even better with the Sky-Watcher 254N EQ5 PRO Newtonian Reflector Telescope, such as diffuse emission nebulae in the summer sky like the Lagoon(M8), Trifid(M20), and Swan(M17), The winter sky's Great Orion Nebula(M42) in Constellation Orion, and the beautiful Rosette Nebula in Constellation Monoceros which takes on the appearance of blooming.
The classical Newtonian optical design of this Reflector Telescope by Sky-Watcher utilizes a parabolic shaped primary mirror, and an ellipse shaped diagonal mirror suspended by a holder and vane assembly in the front of the optical tube. The diagonal mirror projects the image through an opening in the optical tube to the observing position at the focuser-assembly. The tube length of a classic reflector telescope is longer than that of of a Schmidt-Cassegrain Telescope because the Schmidt-Cassegrain Telescope folds the focal length back on itself. Unlike the upright terrestrial image orientation provided by refractors and mirror-lens reflectors, the classic Newtonian presents images upside-down. However, this is perfectly acceptable for astronomical use where directional orientation is relative. The powerful advantage of the Newtonian design is lower cost. Compared to a refractor or mirror-lens design of equal aperture, a Newtonian provides higher resolution per dollar invested.
