  • Enjoy the flexibility of a Variable Polarizing Filter Set when viewing the Moon, Venus, and other bright objects!
  • This Future Optics Variable Polarizer consists of two polarizing filters. One filter has threads on the bottom that attach securely to your 1.25" eyepiece or other 1.25" threaded barrel, and the second filter rotates 360°.
  • Turning the polarizing filter will provide varying degrees of transmission, so that you can adjust how much incoming light you block based on the circumstances.
  • It is like having "transition sunglasses" for your telescope; bright light can be filtered more heavily by the simple turn of the top filter. If you make adjustments while you are looking through the telescope, you will easily see where the best position is for the filter.
  • This filter is not for solar observing. It can, however, be used in the daytime if you are using your telescope on terrestrial objects, and at night when looking at the Moon and brighter planets.

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.

Questions & Answers

Product Questions

is this filter green like my old moon filter or neutral?

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?
