- The Antares Variable Cross Polarizing eyepiece filter acts like a dimmer switch for your telescope, to tone down brightness and accentuate the contrast of bright celestial objects
- It 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
- It consists of two high-grade glass polarizing filters in an 1.25" rotating anodized aluminum cell
- Threaded for use with any 1.25" telescope eyepiece equipped with filter threads
Neutral density filters can reduce brightness across the visual spectrum without losing resolution, enhancing lunar-planetary observation.
Can be used stacked with color filters. The 1.25" FXP varies transmission from 40%-3% and threads into all 1.25" accessories.
