This set of three imaging filters includes the most vital filters for optimizing monochrome planetary portraits; includes an ultraviolet "UV" filter; infrared "IR" filter; and methane "CH4" filter Ultraviolet "UV" filter enhances details of atmospheric structures: The included ultraviolet "UV" short pass filter transmits light wavelengths between 300nm and 400nm; while blocking all wavelengths above 300nm and below 400nm Improve Clarity: The infrared "IR" long pass filter transmits light with wavelengths of 650 nm and above; used for high-contrast imaging of the Moon and planets; the infrared filter also provides excellent image steadiness when seeing conditions are poor Methane "CH4" filter boosts contrast and reveals high altitude atmospheric features: The narrowband methane "CH4" filter transmits the specific methane wavelength of 890nm with a 10nm bandwidth; while blocking all other wavelengths Includes protective plastic case with die-cut foam insert; since each included filter passes wavelengths outside of the visible spectrum; they are intended for imaging use only; a monochrome astrophotography camera is required when using this filter set
