Explore Scientific Eyepiece 62° LER Ar 5.5mm 1.25" (55994)

Explore Scientific's 62° eyepieces provide outstanding edge definition, even when used with fast optics and a wide visual field. Their generous pupillary distance ensures users can view the entire field comfortably, even while wearing glasses. These eyepieces are designed to minimize fatigue caused by awkward neck angles or prolonged observation, offering an exceptional viewing experience.

The argon gas filling prevents internal fogging, while the watertight seal protects against dust, lens fungus, and cleaning fluids. This durable design ensures years of reliable performance and observational enjoyment.

Additional Features:

• Patented EMD coating for maximum contrast

• Carefully blackened lens edges to reduce reflections

• Stainless steel sleeve with a conical safety groove

The abbreviation "LER" stands for long eye relief, meaning these eyepieces offer a large pupillary distance, making them ideal for glasses wearers.
