Celestron EdgeHD 8" Telescope Optical Tube Assembly 91031-XLT is an extremely powerful telescope component that is designed to help you see incredibly distant objects in the night sky such as star clusters, galaxies, and nebula. These potent telescopes utilize EdgeHD optics, premium StarBright XLT coatings, and a wide eight inch aperture to create extremely bright, high-clarity images of the farthest cosmic bodies. With a large focal length of 2032mm and a 40mm eyepiece, you can achieve high magnification rates with the Edge HD telescope without sacrificing any image clarity. Celestron has built the tube of the Celestron Edge-HD 8in Telescope Aplanatic HD Optical Tube out of durable aluminum, and it is equipped with a dovetail rail that can mount easily to a Celestron CG5 mount. Mirror support knobs on the Celestron telescope reduce image shift by holding the mirrors steadily in place during imaging for sharp, non-blurred images at high magnification. The Celestron Edge HD 2032mm Focal Optical Tube Assembly operates efficiently, with an integrated 60 micron mesh filter that releases hot air from behind the primary mirror, keeping the telescope cool throughout your observation.

The Celestron EdgeHD StarBright XLT 8 Inch Telescope Optical Tube delivers true astrograph quality with its Celestron Edge HD optics system, which gives an incredibly flat focal plane with edge to edge clarity and brightness. This particular model in the Celestron EdgeHD series features a visual backplate that allows you to easily mount 1.25" telescope accessories to the tube, including Barlow lenses, reducers, and extra eyepieces. A 9x50 finderscope is included with the Celestron EdgeHD 8in Aluminum Aplanatic Telescope Optical Tube Assembly and can be mounted to the top of the telescope to expand your field of view when you're trying to locate new subjects in the night sky. The optical tube is even comfortable to use when you're looking at objects at a high angle, thanks to the included star diagonal. For a powerful optical tube assembly with a flat focal field, enhanced mechanics, incredibly precise optics, and amazingly clear visuals, install the Celestron Edge-HD 8in Astrograph Optical Tube Assembly.
