The most interesting was a selective bandpass filter to cut a good part of light pollution and greatly intensify the H-alpha wavelength of the visual spectrum to working as a whole like an RGB-Intensifier. The effect is very impressive though, especially if applied on the planets Jupiter and Mars, while at the same time considerably darkening the sky background.
