ED80 Air-Spaced Triplet Refractor Telescopes

The Explore Scientific ED80 is an 80mm air-spaced triplet apochromatic refractor that has become one of the most popular small APO telescopes for astrophotography and travel. Its extra-low dispersion triplet optics deliver sharp, color-corrected images, while its compact size and light weight make it easy to carry, mount and set up anywhere.

An 80mm refractor with a moderate focal length provides a wide field of view, making the ED80 ideal for imaging large deep-sky targets such as the Andromeda Galaxy, the Orion Nebula, the Pleiades and the North America Nebula. Its light weight means it rides easily on compact tracking mounts like the iEXOS-100, making it a forgiving and affordable platform for beginning astrophotographers. Visually, the ED80 delivers crisp, high-contrast views of the Moon, planets and wide star fields.

The ED80 is available in Essential Series and FCD100 Series versions, and in packages with a field flattener, 0.8x focal reducer or iEXOS-100 tracker. For imaging, a flattener or reducer ensures round stars across the frame; for visual observing, add a quality diagonal and eyepieces. Whether used as a primary imaging scope, a travel telescope or a guide scope, the ED80 is a versatile performer.
