This filter set is perfect for anyone who owns a monochrome CCD camera and wants to make color images using the trichromy technique. Using monochrome CCD camera, you record 3 images (one for each filter) which can then be added together with appropriate software (indicating that each filter corresponds to one of the R, G and B channels) to reconstruct the color image! Selecting only particular wavelengths and eliminating light pollution, these filters dramatically increase the contrast of the image so that the background sky turns black making appear areas and details of the nebulae that are not visible without a filter. The filter also decreases the size of the stars highlighting even more nebulae.
The filters are always available in two diameters: 31.8mm and 50.8mm. These standards are commonly used by telescopes and their accessories. For example, depending on their function, they can be used with a CCD ora a DSLR camera (using appropriate photo adapters), but also screwed to optical accessories such as eyepieces or diagonals. Warning: 31.8mm filters do not work with 50.8mm diameter accessories and vice versa (unless there are special adapters). When you choose the version of your filter, be careful to identify the diameter compatible with your equipment.
