Explore Scientific 100° and 120° Eyepieces

Explore Scientific 100° and 120° eyepieces have some of the widest apparent fields made, so the field stop sits at the edge of your vision. The 100° series includes 5.5mm, 9mm, 14mm, 20mm and 25mm models in 2" barrels and a 30mm in a 3" barrel, while the 120° 9mm goes wider still.

All are waterproof and argon-purged against internal fogging. They suit deep-sky observers with Dobsonians and fast telescopes who want large star fields at useful magnification.
