Variable Polarizing Filter

This versatile 1.25" Orion Variable Polarizing Telescope Filter acts like a dimmer switch for your telescope, toning down the brightness of the Moon or planets to a comfortable level and revealing more surface details.

It consists of two high-grade glass polarizing filters in a rotating cell that allows you to vary the amount of light transmission from 1 to 40%. Such control is highly desirable for lunar observing because the Moon's brightness varies with its phase and with the aperture and magnification of the telescope you are using. It's also a must for viewing the Moon in daylight hours.

Reducing the glare to an optimal level will reveal dramatically more lunar and planetary features, without significantly altering the objects' color.
