Its advanced optical system corrects more than just off-axis coma, providing an astrograph-quality flat focal plane that maintains sharp, detailed images all the way to the edge of the field.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTrue Astrograph Quality\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eMany telescopes marketed as “astrographs” produce pinpoint stars across a curved focal plane. While this may be suitable for visual observing, it can cause stars near the edges of a flat digital camera sensor to appear out of focus. EdgeHD optics feature a focal plane that is more than three times flatter than a standard Schmidt-Cassegrain telescope and significantly flatter than competing coma-free designs, helping deliver sharp, well-focused stars across the entire field, even with some of the largest CCD sensors available today.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eImproved Performance\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eSuperior edge performance produces rounder, more natural-looking stars while improving resolution and limiting magnitude compared to telescopes with the same aperture. Combined with Celestron’s StarBright XLT optical coatings applied to every optical surface, EdgeHD optics maximize light transmission across a broad visual and photographic spectrum.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMechanical Features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eIn addition to EdgeHD’s optimized optical design, the telescope tube has been redesigned to make sure you get the most from your optics each and every night.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMirror clutches\u003c\/strong\u003e - 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).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTube vents\u003c\/strong\u003e - Cooling vents located on the rear cell allow hot air to be released from behind the primary mirror.

At its native f\/11, you can achieve the image scale necessary to capture the smallest of deep sky objects. Add the optional reducer lens—custom-designed for your size EdgeHD tube—and 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.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eIndividually Tested\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eEvery 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.
