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 | • Optical system: | the apochromatic triplet | | • Lens diameter: | 80 mm | | • Focal length of the lens: | 480 mm | | • Lighted: | f / 6 | | • Switching capacity: | 1.45 '' | | • Theoretical range: | 12 magicians | | • Anti-reflective layers: | EMD (Enhanced Multilayer Deposition) | | • Length of the optical tube: | 38 cm (without diffuser) / 47.5 cm (with difler) | | • Diameter of the tube: | 85 mm | | • Weight: | 3.4 kg (without packaging) |
