Part: 91030-XLT Item Includes40mm 1.25 " Eyepiece - 9x50mm Finderscope - 1.25 " 90-Degree Mirror Diagonal - 2-Year Warranty DescriptionSee the Universe in HD EdgeHD is an aplanatic, flat field Schmidt-Cassegrain telescope that produces aberration-free images across a wide visual and photographic field of view. The optical system was designed to reduce more than just off-axis star coma; it also provides an astrograph-quality flat focal plane all the way to the edge of the field of view. True Astrograph Quality Many optical designs that advertise themselves as "astrographs" actually only produce pinpoint stars across a curved focal plane. While this may be acceptable for some visual observing, stars will appear out of focus at the edge when used with the flat chip sensor of a digital camera. EdgeHD optics produce a focal plane more than three-times flatter than a standard Schmidt-Cassegrain telescope and dramatically flatter than competing coma-free designs. This guarantees you visibly sharp stars across some of the largest CCD chips available today. Improved Performance Superior edge performance not only creates rounder, more pleasing stars, but actually improves the resolution and limiting magnitude when compared to telescopes of equal aperture. With Celestronfs StarBright XLT optical coatings on every surface, EdgeHD optics gives you maximum light throughput across the widest visual and photographic spectrum. Mechanical Features In addition to EdgeHDfs optimized optical design, the telescope tube has been redesigned to make sure you get the most from your optics each and every night. Mirror clutches - Flexible tension clutches hold the mirror in place and reduce image shift when taking long exposure astro-images. Once focused, the flexible rods allow the mirror to be held in place without putting any force or pressure on the mirror assembly, keeping the image centered in the eyepiece (or on the sensor). Tube vents - Cooling vents located on the rear cell allow hot air to be released from behind the primary mirror. Each vent has an integrated 50-mesh filter guaranteed to let warm air out without letting dust in. Fastar versatility - EdgeHD is the most versatile imaging telescope available today. At its native f/10, you can achieve the image scale necessary to capture the smallest of deep sky objects. Add the optional reducer lensfcustom-designed for your size EdgeHD tubefand you can increase your field of view without sacrificing optical performance. A Barlow gives you added power for high-resolution planetary, lunar and solar imaging. All EdgeHD optical tubes are Fastar-compatible, allowing the secondary mirror to be removed and replaced with a third party lens accessory for ultra-fast f/2 wide field imaging. Individually Tested Every EdgeHD that ships has been tested not only for the surface quality of each optical component, but also with a camera and artificial star to ensure the imaging system meets our rigid quality assurance. This ffinal acceptance testf confirms the EdgeHD will perform in the field and deliver high-quality astroimages.Features8" EdgeHD Optical Tube AssemblyAluminum Optical TubeCelestron's premium StarBright XLT coatings2032 mm focal length (f/10)40 mm eyepiece included (51x)Visual back allows for use with 1.25" accessories9x50 finderscope to help accurately find objectsStar diagonal provides more comfortable viewing position when observing objectsthat are high in the skyMirror Support Knobs hold the mirror in place and reduces image shift during imaging.Tube vents with integrated 60 micron mesh filter allowing hot air to be released from behind the primary mirror.Fastar Compatible optical tubes are equipped with a removable secondary mirror for fast f/2 ccd imagingIncludes dovetail rail compatible with CGE mount .
