Explore Scientific LER Ar 1.25", 20mm, 62° eyepiece (53322)

Explore Scientific's 62° eyepieces are designed to deliver exceptional edge definition, even with fast optics and a large visual field. Their generous pupillary distance allows users to comfortably view the entire field, even while wearing glasses. These eyepieces reduce fatigue caused by awkward neck angles or prolonged observation, ensuring a more enjoyable viewing experience.

The argon gas filling effectively prevents internal fogging, while the watertight seal protects against dust, lens fungus, and cleaning fluids. This durable design guarantees years of high-quality observational enjoyment.

Additional Features:

• Patented EMD coating for maximum contrast

• Carefully blackened lens edges to minimize reflections

• Stainless steel sleeve with a conical safety groove

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