Color filters are of great help when observing the planets with a telescope. They help discern small and low-contrast features on the planetary discs. But there are so many color filters available that one can easily get lost. Even the manufacturers' recommendations are of no great help, since they are mostly for larger apertures of eight inch and more. Here we present a recommended filter set that matches perfectly with a small telescope.

The filters #8 light yellow, #21 orange, #80A blue and Baader Neodymium are an ideal combination for planetary observing with a small refractor, Maksutov or Newtonian telescope. For those who want to add a new dimension to their lunar and planetary observing sessions we compiled an in-depth description of this nice filter set for download.
