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.
