New Main: Planetary/Colour filters
Planetary filters, also known as contrast filters, are designed to enhance the visibility of details on the surfaces of planets, such as Jupiter's cloud bands or the polar ice caps on Mars. These filters work by blocking certain wavelengths of light, such as blue or green, while allowing other wavelengths to pass through. This can help to enhance the contrast between light and dark areas on the planet, making it easier to see details that would otherwise be difficult to discern.
Colour filters, on the other hand, are designed to enhance the visibility of specific colours in celestial objects. For example, a red filter can be used to enhance the visibility of features on Mars, while a green filter can be used to enhance the visibility of details on Jupiter or Saturn. Colour filters work by selectively blocking certain wavelengths of light, allowing the desired colours to pass through
