Explore Scientific 82° Series LER Eyepiece

This eyepiece features a standard 1.25-inch barrel diameter, making it compatible with the vast majority of modern telescopes that accept 1.25-inch accessories.

An 82-degree apparent field of view provides an immersive, 'spacewalk' experience, allowing you to see a much wider area of the sky at once compared to standard eyepieces. This helps you locate objects more easily and provides a more natural, expansive view of deep-sky targets.

Yes, the 'LER' in the product name stands for Long Eye Relief. With 15.9 mm of eye relief, it is designed to be comfortable for most observers, even those who need to keep their glasses on while viewing.

The eyepiece is argon-purged and sealed to be waterproof, which prevents internal fogging and keeps dust or moisture from entering the optical assembly. This ensures the optics remain clean and clear even when observing in humid or rapidly changing temperature conditions.

A 4.5 mm focal length provides high magnification, making it an excellent choice for detailed planetary observation or viewing small, bright deep-sky objects like globular clusters and planetary nebulae. It is best used on nights with steady atmospheric conditions to get the sharpest possible view.
