An ideal addition to your telescope accessory kit, the 2" Ice Lipo Light Pollution Filter is a jack-of-all-trades multi-tasker that, when used by itself or stacked with colored planetary filters, will enhance your views and appreciation of the night sky. This model of the Ice Lipo is designed to fit larger 2" eyepieces and accessories.
The filter is designed to block specific wavelengths of light, targeting those bands that are transmitted by artificial light such as mercury vapor and high- and low-pressure sodium vapor lights. By blocking this stray atmospheric light, the filter turns the sky a pitch black for enhanced contrast of bright and dim objects against the backdrop of space. It also helps to correct chromatic aberrations on refractors and removes the bluish tint, or lack of contrast, that is common during lunar and terrestrial observation to produce natural and neutral colors.
