In the construction of solar filters and associated instrumentation, Coronado takes enormous care to optimize contrast by minimizing the number of components and designing them so that they do not result in creating residual reflections and spurious light near the image. Until recently, the only component not included in this overall approach was the eyepiece. Now CEMAX (Contrast Enhanced) series eyepiece fills this need. Specifically designed for use at H-Alpha and multi coated on every surface (included cemented surfaces), the CEMAX eyepieces are the ultimate in contrast enhancement for the solar observer. CEMAX eyepieces have also been used successfully for planetary viewing. Kit includes three CEMAX eyepieces, 12mm, 18mm and 25mm, and a 2x Barlow, all in the 1.25" size. All telescope eyepieces feature 20mm eye relief.
Important note: CEMAX eyepieces are not solar filters and cannot be used for solar observing without a safe solar filter. There is the possibility of instant eye injury without using a proper solar filter while viewing the sun.

The edge-to-edge angular diameter of the image displayed in a binocular as seen by the eyes of the observer. It is an inherent specification for a given binocular design. The "angular diameter" of an object is defined as the angle an object makes (subtends) as seen by an observer.
Binocular lenses and prisms are often coated with anti-reflective material to minimize light loss as light travels through the multiple optical surfaces of a typical binocular. Coatings help maximize the amount of light transmitted through each glass surface of a binocular, so as much light as possible reaches the observer's eyes to provide a bright and sharp image.
Good lenses are at least "fully coated," with a single layer of magnesium fluoride coating applied to each air-to-glass lens surface. Multiple layers of coatings are even more effective; the term "multi-coated" means one or more air-to-glass lens surface has multiple coatings. "Fully multi-coated" optics are even better, meaning all lens surfaces have multiple layers of anti-reflective coatings applied for maximum light transmission and optimal image quality.
