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\u003cp style=\"box-sizing: inherit; margin: 0px 0px 15px; padding: 0px; color: rgb(51, 62, 72); font-family: \" open sans arial helvetica sans-serif font-size:=\"\"\u003e\u003cspan style=\"box-sizing: inherit; font-weight: bolder;\"\u003eImproved Performance\u003c\/span\u003e\u003cbr style=\"box-sizing: inherit;\"\u003eSuperior edge performance not only creates rounder, more pleasing stars, but actually improves the resolution and limiting magnitude when compared to telescopes of equal aperture.
