- The Orion Variable Polarizing eyepiece filter acts like a dimmer switch for your telescope, to tone down brightness and accentuate contrast of bright celestial objects.
- Gives you much finer control of the image brightness compared to a standard fixed-transmission telescope eyepiece filter for optimal performance.
- Adjust the amount of light transmission from 1% to 40% by rotating the eyepiece filter housing
