Omegon Filters 1.25'' L-RGB CCD Filter Set

LRGB filter set: for astrophotography with monochrome CCD cameras

Four filters for a color image: The LRGB filter set is used to photograph the sky in color with a chip monochrome camera. Monochrome CCD cameras used for astrophotography provide a bright image of deep-sky objects with very high resolution, as all the pixels on the chip work together to produce the image. However, resolution is minimized with cameras using color CCD chips, since about ⅓ of the pixels have color filters.

Only one set of LRGB filters with a monochrome camera uses the entire chip and can therefore generate a high resolution color image.

L - the luminance filter

The luminance filter passes through the entire visible light spectrum, but blocks near UV and IR light, so this filter collects all the useful information about the object.

RGB - each filter has a special task

These three letters stand for the three different RGB color filters from which you ultimately create your color photograph. The colors we perceive consist of the three primary colors: red, green, and blue. Combined, these give all the colors we can see. Our eyes also mix all the colors in our world from internal RGB receptors (or filters).

The four images from the LRGB channels are combined in the image processing procedure and essentially create the final color photograph.

Tip: Using the Omegon Filter Wheel with the LRGB Filter Set for your astrophotography allows you to change filters in seconds.
