High Point #58 Dark Green Filter - 1.25"
This #58 Dark Green Filter, 24% transmission by High Point Scientific is an invaluable aid to lunar and planetary observing. Colored filters reduce light scattering and glare while increasing contrast via selective filtration. Colored filters also provide increased definition, reduced irradiation, and lessen eye fatigue. The Deep Green Filter has a Wratten number of #58 and can enhance definition in brighter comets. Easily view cloud patterns on Venus and white features in Saturn's atmosphere. With a transmission of 24%, this dark green filter helps you observe the Great Red Spot on Jupiter, as well as surface features on the Moon. Mars will also benefit from a green filter by enhancing views of the polar ice caps, low clouds, and dust storms.
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.
