Explore Scientific 1.25", 24mm 68° N2-filled eyepiece (25049)

This 68° field of view eyepiece is a waterproof and gas-filled optical instrument designed for superior performance. The gas filling effectively prevents internal fogging, ingress of dust and moisture, and formation of fungal blooms. This protection ensures that the high-quality multi-coating remains well-preserved and durable. Cleaning is simplified, as the eyepiece can be treated with cleaning fluid without risk, and even heavy internal condensation cannot penetrate between the lens elements. These features guarantee perfect observing conditions for many years to come.

Image quality is not compromised, as the eyepiece provides a sharp, high-contrast image across the entire field of view, even with 'fast' telescopes. The use of high-quality glass, blackened lens edges, and the patented EMD multi-coating ensure maximum contrast.

Additional Features:

• Foldable rubber eyecup

• Standard filter thread

• Conical locking groove in the stainless-steel barrel

• Parfocal design within the 68° series, eliminating the need for focus adjustment when switching between eyepieces
