Explore Scientific 80 mm APO from the Essential line is a true apochromatic triplet, with diffraction limited optics, charac- terizing chromatic aberration corrected practically to zero. Made of low-dispersion ED glass from HOYA, it provides excellent contrast. All optical surfaces have been covered with excellent EMD layers.
Excellent equipment for photographing Deep Sky's objects, observing planets and as a telescope for observation and nature photography from a high quality shelf.
• real apochromatic triplet with an air break with 80/480 f / 6, Hoya glass
• all optical surfaces covered with anti-reflective layers EMD (TM) ensure very high efficiency of the system
• the tube is equipped with internal diaphragms and carefully matt blackened, thanks to which the reflections are practically eliminated
• retractable diffuser slows the dew condensation process on the lens optics and effectively reduces glare during daytime observation
