The moon, unfiltered, is too bright. A variable polarizing filter really works well. The have special filter for each individual object in space that helps few that specific object.. one for Mars, another for Jupiter, etc.... but for me the polarizing filter for the Moon was the biggest help of them all.
Personal taste comes into play... which is why I suggested a variable... but almost certainly you'll see improved detail no matter how 'dark' you adjust it too. - JamesJM
