A simple and affordable solution to a frustrating problem, our Zhumell Ultra High Contrast Filter is available in both 2-inch and 1.25-inch format eyepieces to suit your needs. It works by filtering out specific wavelengths of light to expose objects invisible the naked eye or unfiltered telescope eyepieces.
