  1. Hey Charlie, not a dumb question at all!
    I’m imaging through narrowband filters that don’t pass most of the wavelengths of light given off by Sodium and Mercury-vapor lights. If you’re imaging with a DSLR or a colour CCD you can get broadband light pollution filters that can help a fair bit too.
    Clear skies :-)

  2. Depends on the filter, I’ve used an Astronomik CLS and it gave the images a blue tint, mostly fixable. I’ve heard good things about the Hutech IDAS also.
