High Point #58 Dark Green Filter - 1.25" - 58F1
High Point #58 Dark Green Filter - 1.25"
This High Point Colored Filter has a Wratten number of #58, which is considered Dark Green. It has a transmission of 24%. A green filter can help you see the Great Red Spot on Jupiter, as well as lunar features on the Moon. Mars observations are enhanced pretty much across the board, including the polar ice caps, low clouds, and dust storms. You can also more easily see the cloud patterns on Venus with the #58 green filter, see white features in Saturn's atmosphere, and observe brighter comets.
Colored filters can be 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.
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 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. It therefore makes sense that the larger the optics, the more likely you will have success with filters, especially those with less light transmission.
