Its 120mm air-spaced objective includes one element of FPL-53 extra-low dispersion glass in a matched lens assembly, and its 900mm focal length at f\/7.5 gives a generous image scale for the Moon, the planets and smaller deep-sky targets. Sky-Watcher's Metallic High-Transmission Coatings (MHTC) and internal baffling keep stars sharp against a dark, high-contrast background.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003e120mm FPL-53 Doublet with MHTC Coatings\u003c\/h3\u003e\n\u003cp\u003eThe Evostar EDX 120 uses a two-element, air-spaced objective built from a matched lens set that includes one FPL-53 extra-low dispersion element. This apochromatic design virtually eliminates false color, so bright stars and planetary limbs stay free of purple fringing. The objective is multi-coated with Sky-Watcher's Metallic High-Transmission Coatings (MHTC), and internal baffles block stray light before it reaches your eyepiece or camera.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003e44% More Light Than the Evostar EDX 100\u003c\/h3\u003e\n\u003cp\u003eMoving from 100mm to 120mm of aperture increases light-gathering area by 44%.
