Orion 1.25" Variable Polarizing Telescope Filter

Discuss this article in our forums
Looking at the full moon through a 10" dobsonian can be blinding. It is so bright it is hard to look at and will ruin your night vision. The Orion Variable Polarizing Filter makes viewing the moon a more pleasurable experience. Unlike a neutral density filter that lets a set amount of light though this one allows you to control the amount of light transmission from 1% to 40%. It screws on to the end of your eyepiece and you rotate it to vary the light transmission. I find this better than a neutral density filter because you can vary the amount of light according the phase of the moon. By reducing the glare it helps bring out more detail. The only thing I don't like about it is that you have to remove your eyepiece in order to adjust it.
