Re light pollution filters:
They do work, to an extent. Broadband filters improve contrast by darkening the background sky. Narrowband go one better by blocking more light, and they are absolutely fantastic for emission nebula. But they both ruin galaxies, as they emit exactly the kind of light that the filters block. For planetary viewing, you won't need them, the planets are bright enough.

Clear skies,
Shane
