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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTrue Astrograph Quality\u003c\/strong\u003e\u003cbr\u003eMany 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. \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMechanical Features\u003c\/strong\u003e\u003cbr\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\u003cspan\u003e \u003c\/span\u003e- Flexible tension clutches hold the mirror in place and reduce image shift when taking long exposure astro-images.

At its native f\/10, you can achieve the image scale necessary to capture the smallest of deep sky objects. A Barlow gives you added power for high-resolution planetary, lunar and solar imaging.
