Explore Scientific 6.7mm 82° eyepiece 1.25″
Looking for an eyepiece that delivers a truly immersive experience when observing star clusters, nebulae or planets? The Explore Scientific 6.7mm eyepiece from the 82° Series is exactly what you need. It combines an apparent field of view of 82° with a focal length of 6.7mm and a barrel diameter of 1.25″, making it compatible with the vast majority of amateur and semi-professional telescopes. The result is a bright, high-contrast and geometrically accurate image that will not leave you indifferent.
Optical construction and image quality
The eyepiece is built around a proven 7-element, 4-group optical design that delivers excellent correction of optical aberrations across the entire field of view - from the centre to the very edge. All optical surfaces feature fully multi-coated anti-reflection coatings, lens edges are blackened, and the inner barrel is matte black to eliminate unwanted reflections and light scatter. The result is high contrast and outstanding image quality even under demanding observing conditions.
The eyepiece is purged with nitrogen or argon, which prevents internal fogging of the optical surfaces when working in cold and humid conditions - something you will appreciate during every night session outdoors.
Comfort during observation
An eye relief of 15mm is an above-average value for a 6.7mm focal length - you do not need to press your eye tightly against the eyepiece, which significantly reduces fatigue during extended observing sessions. The retractable rubber eyecup with a twist-up mechanism allows smooth height adjustment to suit individual preferences, and can be used comfortably with glasses.
Experienced astronomers know well that eye comfort is decisive when you are trying to get the most out of your telescope - whether you are hunting a faint galaxy using averted vision or concentrating on fine details in planetary nebulae.
Wide field of view - a window to the universe
A wide-angle eyepiece with an 82° field of view gives the observer the feeling of a true window onto the universe. When used in shorter refractors or Newtonians of moderate focal length, the 6.7mm focal length will provide medium to high magnification - ideal for detailed study of open star clusters, planetary nebulae and bright globular clusters.
Who is this eyepiece for?
The Explore Scientific 6.7mm 82° eyepiece will be appreciated by both experienced amateur astronomers looking for proven optics with an excellent performance-to-price ratio, and beginners who want to invest in quality accessories that will last throughout their entire astronomical journey. Thanks to the standard 1.25″ barrel diameter, it can be used with virtually any telescope on the market.
