Future Optics Variable Polarizer for 1.25" Eyepieces
The Future Optics Variable Polarizer is a great tool to have in your astronomy accessory box. Simply screw it onto the end of an 1.25" eyepiece, and then turn the top filter until the amount of filtering that takes place is pleasing to your eye. A variable polarizer works wonders on the Moon and other bright objects, like the planet Venus. Sometimes the moon is so bright that your eyes are unable to see all but the most obvious details. It can be similar to staring into a headlight, especially when viewing with larger telescopes! A common solution for this problem is the "moon filter". It does what it is supposed to do, but the benefit of a variable polarizer over a standard moon filter is the ability to adjust the brightness level. Therefore, when viewing a full moon you would most likely crank it all the way up, but when viewing a crescent moon, or other objects that are less bright, you can turn the rotating filter until the brightness is dimmed just a little.

Product QuestionsWhat is the range of brightness attenuation adjustments on this Future Optics Variable Polarizer ?Can the two polarizers be seperated, to put one on the diagonal, and one on the eyepiece, so you only have to rotate the eyepiece itself to adjust brightness?Question by: bill on Feb 25, 2014 1:38:54 PMThis one is pretty neutral. Taking a look at/through one in a well lit room, there is no visibly observable color introduced. The perfectionist in me prevents me from saying that it is completely neutral, as we'd be relying purely on my eyes... but this is a far cry from the greenish ND filters often called moon-filters.Answer by: Eric_B (Admin) on Feb 25, 2014 2:48:54 PM
