Its nine element 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 (almost 4.5mm with the typical f\/4.5 Dob). Its very wide field also makes it convenient for moderate power lunar and globular cluster observing with Dobsonians, as you have much longer to observe before the planet drifts out of the field and the scope has to be repositioned than you do with a 60° or 70° (or even 82°) field eyepiece.

It's the widest field of view available in any commercial eyepiece. An astronomy first from Explore Scientific, the 120° apparent field of this new 9mm Explore Scientific shows more than twice the sky area of an 82° eyepiece and even a whopping 44% larger area than a 100° eyepiece.\u003c\/p\u003e\n\u003cp\u003eThe prototype 9mm was field-tested for the first time at Starfest in Canada, August 2011. Experienced astronomers who waited in line to get a chance to view through the hyperwide 120° Explore Scientific 9mm were stunned by the full-immersion observing experience. Even when compared with a 9mm 100° field eyepiece, the difference was \"quite palpable,\" to quote one experienced observer. The telescope seemed to truly disappear in the 120° field, bringing them face to face with the Universe in an intimate and personal way never before possible. It's an awe-inspiring observing experience you can repeat for yourself every night you go out with your scope.\u003c\/p\u003e\n\u003cp\u003eThis deep sky eyepiece, the first of its kind for astronomy, produces a highly corrected field across its entire 120° apparent field. The views of compact globular clusters, nebulas, and galaxies are breathtaking. You can use the field of view calculator under the formula tab above to see just how much sky the Explore Scientific can reveal with your telescope.\u003c\/p\u003e\n\u003cp\u003eThe Explore Scientific 9mm is designed specifically for nighttime deep sky observing. It is not an eyepiece for daytime use and will show some lateral color at the edges of the very wide field in daytime use.

Internally sealing the eyepiece and purging it with inert, dry argon gas (which has lower permeability through the eyepiece's polymer seals than nitrogen) prevents internal fogging in the eyepiece when observing at sub-freezing temperatures.

For observers in very humid climates, sealing prevents the growth of fungus on the internal lens elements.

You may be startled at the amazingly wide expanse of inky black sky you behold the first time you bring your eye to a 100° Series eyepiece, and after awhile, you may even forget that you have an eyepiece between you and the universe!

Between complex mounts, confusing specs, and all those technical terms, it’s easy to wonder where to begin.
