Explore Scientific Eyepiece 82° Ar 4.7 mm 1.25″

Explore Scientific 82° Ar 4.7mm: Maximum Planetary Magnification with Wide Field of View

The Explore Scientific 82-degree AR 4.7mm is a waterproof, argon-filled wide-angle eyepiece. The argon filling definitively keeps moisture, dust, and mold out of the optics: the eyepiece will not fog up internally and is even rinseable when cleaning.

With a 4.7 mm focal length, this is the eyepiece for the highest magnifications: moon craters at their sharpest, Saturn's ring divisions, and detail on Mars under calm skies.

82 degree field of view

The apparent field of view of 82 degrees gives the feeling of looking into space instead of through a tube. Furthermore, on a Dobsonian without a tracking motor, objects remain in view longer before you need to make adjustments.

EMD coating

The patented EMD (Enhanced Multilayer Deposition) coating increases light transmission and suppresses reflections and ghosting, leading to a high-contrast image right to the edge, along with blackened lens edges.

Built for years of outdoor use

The all-metal housing is argon-filled and sealed. The flip-up eyecup allows for eyeglass wearers, and the connection size has filter threading for color and haze filters.

Featured accessories

Combine this eyepiece with a moon filter or a planetary observation filter set and an eyepiece case for safe transport. The filters from the Explore Scientific filter sets fit directly into the 1.25-inch thread.

For whom yes and for whom no

• ✓ Observers who want a waterproof, wide-angle eyepiece that can withstand dew and field use
• ✓ Dobson owners who want to keep objects in view longer
• For those who mainly observe deep-sky objects at low power: choose a longer focal length or a 2-inch eyepiece.
