Product Details

  • This versatile variable polarizing filter by Orion acts like a dimmer switch for your telescope, toning down the brightness of the Moon or planets to a level that is comfortable. The reduction in brightness and glare unmasks detail in your viewing subject and greatly improves contrast, and unlike regular moon filters, you can adjust the amount of dimming to match the brightness of your subject. 

    The Orion Variable Polarizing Filter consists of two high-grade glass polarizing filters in a rotating cell that allows you to adjust the amount of light transmission from 1 to 40-percent. Such control is highly desirable for lunar observing because the Moon's brightness varies depending on its phase. The filter is great for terrestrial observing too, especially on sunny days.

    The filter has an anodized aluminum cell, which threads into the barrel of any standard 1.25-inch or 2" eyepieces. Storage case included.

It does what it says

Easy to assemble and use. However, very little movement is needed to effect a large change in transmission, so it could be fiddly for some, especially with gloves. The first use was with the Orion Premium Binoviewer on a 7" Mak-Cass at the Moon. Wow - what a sight - and no more night-vision loss with this little gem. It does what it says, just as it should.
