Celestron EdgeHD 1100 XLT Optical Tube Assembly - 91050-XLT Celestron EdgeHD 1100 XLT ® Optical Tube Assembly - 91050-XLT SKU: 91050-XLT The EdgeHD 11 Optical Tube Assembly from Celestron features an Aplanatic Schmidt- Cassegrain optical system. This compound, or catadioptric, light-path employs a combination of mirrors and lenses that offer a large high-resolution aperture, a shorter tube length, and enhanced portability. This telescope has an 11" aperture, a focal length of 2800 mm, and a focal ratio of f/10. The EdgeHD optical system consists of a zero power corrector plate, a spherical primary mirror, and a secondary mirror along with a set of field flattening lenses integrated into the baffle tube. The optics of an EdgeHD telescopes feature StarBright XLT multi-layer coatings on the... Less

The Skywatcher 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 Skywatcher 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... Less

The VMC200L is a unique catadioptric optical system. It incorporates a primary mirror and a meniscus corrector just before a secondary mirror. By doing so, light is corrected twice on the optical path. The end result is that spherical aberration and field curvature are corrected to a high degree of optical performance. The VMC200L’s primary mirror is f/2.5; the compound optical system is f/9.75. This makes the system much more compact and portable than its competition. With the optical correction placed before the secondary mirror, the VMC200L avoids the necessity of having a corrector plate and all the dewing problems associated with a closed optical tube.
