LRGB Filter Set - Astrophotography with Monochrome CCD Cameras Four filters for a color image: With the LRGB filter set you can take color sky photos with a monochrome chip. Monochrome Astro CCD cameras illuminate deep sky objects with extremely high resolution, as all pixels act together in one image. With a color CCD chip, resolution is lost because ⅓ of the pixels have color filters.
For a very high resolution image it is necessary to use a set of LRGB filters and a monochrome camera.
L - The luminance filter It allows all visible light to pass through and blocks UV and IR rays, so that all the information about the object reaches the observer.
RGB - Each filter has its special mission Each of these letters represents the color (in English) that they highlight. The colors that we appreciate are formed from three basic colors: red, green and blue. Our eyes also mix colors with RGB receptors so that we are able to recognize all shades.
The four images from the LRGB channels are combined to create the final color image.
All the advantages:
