    Explore Scientific 25mm 100 Degree 2" Waterproof Eyepiece EP10025-01 Shopping


    Best Review Explore Scientific 25mm 100 Degree 2" Waterproof Eyepiece EP10025-01

    This on-line sellers provide the best quality and save expense price which included super save shipping (in U.S.A. only) for Explore Scientific 25mm 100 Degree 2" Waterproof Eyepiece EP10025-01. Reading opinions delivers you having a a whole lot of fuller info on the cons and pros of the Explore Scientific 25mm 100 Degree 2" Waterproof Eyepiece EP10025-01.




    Explore Scientific 25mm 100 Degree 2" Waterproof Eyepiece EP10025-01

    The Explore Scientific new 25mm, 100 Degree field, 2" eyepiece is argon-purged and O-ring sealed to be 100% waterproof. Explore Scientific did various tests on ever eyepiece in one meter of water for 30 minutes to ensure perfect seal before shipping.

    The Explore Scientific 25mm eyepiece is superb under almost any weather conditions. With the internal sealing of the eyepiece and purging it with inert, dry argon gas prevents internal fogging in the eyepiece when observing at sub-freezing temperatures. In dusty climates, the sealing effectively keeps wind blown dust and fine particulates from entering the eyepiece body. If observing in a more humid climate, the sealing prevents growth of fungus on the internal lens elements. Overall, the complete sealing and testing of the Explore Scientific 25mm eyepiece maximizes the life of the internal optical coatings while also making the eyepiece easier to clean.

    The 25mm Explore Scientific eyepiece has high contrast, comfortable eye relief, and full field sharpness - with well-controlled astigmatism, field curvature, and lateral color. Its optical system (using lenses of dense crown, light crown, dense flint, and lanthanum rare earth optical glasses) is designed for maximum field/medium power deep space use with telescopes having focal ratios down as low as f/4. It is exceptionally effective on nebulas with fast f/ratio reflectors, such as Dobsonians, as it gives both an immense field and a bright exit pupil (over 5.5mm with the typical f/4.5 Dob). Convenient for moderate power globular and lunar cluster observing with Dobsonians is made possible with its very wide field. You will also have a much longer time to observe before the planet drifts out of the field and the scope has to be repositioned than you would with a 60, 70 or 82 degree field eyepiece. The Explore Scientific 25mm eyepiece is a superb tool for observing nebula
