    High Point #11 Yellow Green Filter - 1.25"

    This #11 Yellow Green Filter, 40% transmission by High Point Scientific is an invaluable aid to lunar and planetary observing. This filter will reduce glare and light scattering, increase contrast through selective filtration, increase definition and resolution, reduce irradiation and lessen eye fatigue. The Yellow Green Filter has a Wratten number of #11 and darkens the maria on Mars. With a transmission of 40%, this green filter will also enhance the Cassini Division between Saturn's rings. If you have a telescope with at least 11" of aperture, you can use a green filter to improve detail on both Neptune and Uranus.

    All of High Point's colored filters are made of high quality, solid plane parallel glass that has been anti-reflection coated to prevent glare and ghosting. They have a full 26mm clear aperture and are mounted in a black anodized aluminum cell that is threaded on both sides to fit most 1.25" eyepieces and stack with each other.

    Please note that the effectiveness of this filter depends on several factors, including the aperture and focal length of your telescope, the magnification being used, and the seeing conditions at the time. Remember that filters lower the amount of light that reaches your eye. You'll need an aperture of at least 8 inches for dark filters such as the #47 Violet, with only 3% transmission, the #25 Red with just 14% transmission, or the #38A Blue with 17% transmission.
