Omegon LRGB pro filter set - color filters for use with monochrome CCD cameras
This LRGB filter set allows you to use your monochrome CCD camera to create high resolution color images.
Monochrome CCD cameras typically offer higher resolution than color cameras. But how do you get a high quality color image with them? - you can, using this LRGB filter set consisting of four parts:
luminance filter - for the monochrome channel
red filter
green filter
blue filter
The individual images from each of these four filters are combined to produce a higher resolution color image. This is because each color channel uses all the pixels in your camera, a very different story than color cameras.
This set is best used in conjunction with a filter wheel, which allows you to easily switch to a new filter after each set of exposures by simply turning the filter wheel. The result is that, image by image, the components of the final composite color astronomical image are exposed.
