Peering into space with a Q70 2-inch eyepiece puts your favorite nebulas and galaxies in a wonderful new perspective. Gas clouds glow and stellar clusters glitter amid a seemingly endless ocean of black space, thanks to the Q70s' super-wide 70-deg apparent field of view. Each Q70 has five lens, multi-coated, high-index glass elements for sharp, high-contrast images with excellent color correction. Eye relief is a luxurious 24mm. All eyepieces in the Q70 series are parfocal, so you can change eyepieces without refocusing. Machined housings have fold-down rubber eyeguards and a rubber grip band. Threaded chrome-plated barrels accept 2-inch filters. Two end caps are included.
