The Explore Scientific 100° Series™ eyepieces are hyper-wide class oculars that can transform your visual astronomy experience. 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! With an apparent field of view that is close to the maximum for hyper-wide eyepiece design, objects are not only easier to locate, but for non-driven telescopes the object will stay in the field of view for a very long time before any adjustments need to be made.
5.5mm, 9mm, 14mm, 20mm, and 25mm eyepieces have a 2" barrel.
The 30mm focal length eyepiece has a 3" barrel.
