Vixen Optics 2" StarGuy Variable Polarizer Filter

Helping to increase the contrast when viewing bright celestial objects with a telescope featuring a 2"-diameter eyepiece, the StarGuy Variable Polarizer Filter from Vixen Optics provides a transmission range of 4 to 50%, making it ideal for extended, detailed viewing of the moon and its features. By adjusting the polarization, you can tune the apparent contrast to suit varying intensities of brightness and reflection and can also observe planets during the daytime, especially when they are 90° from the Sun's location in the sky.
