This versatile 2″ Orion Variable Polarising 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.
The 2″ Orion Variable Polarising Telescope Filter consists of two high-grade glass polarising 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’ colour.
