    High Point #12 Yellow Filter - 1.25"

    This #12 Yellow Filter by High Point Scientific, 74% transmission is an invaluable aid to lunar and planetary observing. Colored filters reduce light scattering and glare while increasing contrast via selective filtration. Filters also provide increased definition, reduced irradiation, and lessen eye fatigue. The Yellow Filter has a Wratten number of #12 and can help you view the many surface features of Mars. It will darken the maria, oases, and canal markings while lightening desert regions that are orange in color. When observing Jupiter and Saturn, this filter will help you study the belts and zones and to darken the subtle blue tones of the atmospheric currents. With a transmission of 74%, this yellow filter increases comet tail definition. If you have a telescope with at least 11" of aperture, you can use a yellow 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.
