What is LRGB filter?
LRGB filter is a type of astronomical filter that is used in digital astrophotography to capture different levels of luminousity and color information. This type of filter consists of four individual filters- red, green, blue, and luminance- which are stacked together in order to produce an image with higher contrast and detail than can be produced by single-band filters. LRGB filters can also be combined with other types of filters (such as hydrogen-alpha or OIII) to create more expansive images.
