With EdgeHD optics, you see sharp point-like stars to the very edges of some of the largest CCD and DSLR chips available today.įor the ultimate in brightness and contrast, the 8' EdgeHD optical tube has state-of-the-art Starbright XLT multicoatings. Stars are smaller and more concentrated, creating brighter images and allowing you to see down to a fainter magnitude than other equally-sized telescopes.

In addition to reduced off-axis coma, the EdgeHD optics deliver an astrograph-quality focal plane more than three times flatter than standard Schmidt-Cassegrains and dramatically flatter than competing coma-free designs. The advanced EdgeHD optical system uses a dedicated dual-element field flattener lens made from premium Schott optical glass in its central baffle tube to reduce off-axis coma and produce aberration-free images across a wide 42mm image circle (as large as the diagonal of a 35mm negative or large format CCD chip and ideal for astrophotography). The compact and easily transportable Celestron 8' EdgeHD optical tube has new and unique 8' aperture aplanatic (free from coma and corrected for spherical aberration) EdgeHD high definition/high contrast Schmidt optics.
