The Orion Q70s' super-wide 70-deg apparent field of view causes gas clouds glow and stellar clusters glitter amid a seemingly endless ocean of black space. It has five lens, multi-coated, high-index glass elements for sharp, high-contrast images with excellent color correction. Eye relief is a luxurious 20mm. The eyepiece in the Q70 is 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" filters. Two end caps are included.
