The CEMAX Eyepiece Set from Coronado is comprised of the CEMAX 12, 18, and 25 mm eyepieces, and the CEMAX 2x Barlow lens. These are high-quality oculars for telescopes that accept 1.25" eyepieces. The Plossl-type eyepieces feature sharp optics, a compact form-factor, long eye relief, and a standard apparent field of view. The 2x Barlow lens doubles the power of the CEMAX eyepieces, and it is designed with a minimum of components to eliminate spurious light.
CEMAX is an acronym for 'Contrast Enhanced'. Designed specifically for use with Coronado's H-Alpha solar viewing systems, CEMAX oculars are fully multicoated to ensure maximum contrast enhancement for solar viewers. CEMAX oculars are not filters. When employed as part of a solar viewing system, they must be used in conjunction with a blocking filter and a SolarMax filter.
