The Orion EON 70mm ED Quadruplet Astrograph is an exceptional wide-field ED astrograph featuring a 350mm f/5 lens system with four-element optics utilizing two Hoya FCD-100 ED lenses for ultimate color correction and contrast. With a 43mm image circle providing almost 6-degrees of sky on a full-format camera, this refractor delivers flat-field imaging for cameras up to 35mm full-format without requiring a separate field flattener. The 360° rotatable focuser enables precise photographic composition, making this astrograph ideal for wide-field astrophotography of the Milky Way, nebulae, and star clusters.
