Celestron Filters

Eyepiece filters are an invaluable aid in lunar and planetary observing. They reduce glare and light scattering, increase contrast through selective filtration, increase definition and resolution, reduce irradiation and lessen eye fatigue. Celestron’s filters are made of high quality, solid plane parallel glass with excellent homogeneity. They’re anti-reflection coated to prevent glaring and ghosting. All eyepiece filters are threaded to fit Celestron’s, and most other manufacturer’s, 1¼" eyepieces, and offer a full 26mm clear aperture.
