Even with binos the moon, especially a full moon is too bight to look at for long, which is a shame because it's fascinating. Well, not anymore. This little filter cuts out the eye watering brightness but does nothing to diminish the view, in fact it seems to enhance the craters and their shadows.

No need to buy anything more expensive, this little filter does a great job at minimizing the glare from the moon (and other bright objects like Saturn and Jupiter). Seems to darken moon images the perfect amount, not too dark to lose any features but definately dark enough to make viewing much more friendly to your eyes.
Improves contrast when viewing the moon.

Does what it says on the tin, this dramatically improves the detail that you can see on the moon's surface.
