Explore Scientific 82° Series Eyepiece

This eyepiece features a standard 1.25-inch barrel diameter, which is compatible with the vast majority of modern telescopes. If your telescope focuser accepts 1.25-inch accessories, this will fit perfectly.

Yes. With 16.3 mm of eye relief, this eyepiece is designed to be comfortable for eyeglass wearers, allowing you to see the full 82-degree field of view without needing to remove your glasses.

The eyepiece is purged with an inert gas and sealed to prevent internal fogging and moisture buildup. This is particularly useful if you observe in humid conditions or experience rapid temperature changes, as it keeps the internal optics clean and clear.

An 82-degree apparent field of view provides an immersive, 'spacewalk' effect where the edges of the eyepiece seem to disappear. This wide view makes it much easier to track objects as they drift across the sky and provides a more expansive context for deep-sky targets.

Edge-blackening reduces internal light scattering and reflections within the eyepiece. This results in higher contrast and darker backgrounds, which helps you see finer details on faint objects like nebulae or galaxies.

An 8.5mm focal length provides medium-to-high magnification, making it an excellent choice for observing the moon, planetary details, and smaller deep-sky objects like globular clusters. It strikes a great balance between magnification and image brightness for most mid-sized telescopes.
