Artesky APO 80ED F/7.0 refractor (SKU: ART80EDF7) is a compact apochromatic refractor designed for astrophotography and visual observing. It features an 80 mm aperture and a 560 mm focal length, and with a dedicated 0.8× reducer it can also operate at 450 mm and F/5.6. The optical design, based on Ohara FCD1-B glass and a lanthanum element, provides very good color correction together with high sharpness and contrast.
