Explore Scientific 52° LER Eyepiece 4,5mm Ar

1. Long Eye Relief (LER): With a generous 20.9 mm of eye relief, this eyepiece greatly enhances viewing comfort, particularly for observers wearing eyeglasses. The extended distance between the eye and the lens allows for a full field of view without discomfort.

2. Argon Purged: Internally purged with inert argon gas, the eyepiece is completely waterproof and resistant to internal fogging. This ensures consistent optical performance in varying weather conditions and prolongs the lifespan of the internal optical elements.

3. 52° Apparent Field of View: This eyepiece provides a comfortable and immersive 52-degree apparent field of view, offering clear and sharp images across the entire field. The view is bright and contrasts are enhanced, bringing out subtle details in celestial objects.

4. Advanced Optics: Featuring a sophisticated optical design with fully multi-coated lenses, the 4.5 mm LER eyepiece delivers exceptional light transmission and minimizes reflections. The result is superior image clarity, brightness, and color fidelity, crucial for detailed astronomical observations.
