OPT #56 Light Green Color Filter for 1.25" Eyepieces

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.

OPT filters are made of high quality, solid plane parallel glass with excellent homogeneity. They are anti-reflection coated to prevent glaring and ghosting. All eyepiece filters are threaded to fit most 1.25" eyepieces and offer a full 26mm clear aperture. Comes with a hinged, plastic case to keep your filter safe and clean when not in use.

#56 Light Green (53% transmission): The OPT 56 Light Green Filter is excellent for the observation of Mars polar ice caps as well as yellow-tinted dust storms on the Martian surface. This filter increases contrast of the red and blue regions in Jupiter’s atmosphere as well as in the cloud belts, and is also useful for enhancing lunar detail.
