The LRGB filter set is designed for maximum contrast and with extremely high gradients for clear differentiation of colours. The LRGB filter set divides the spectrum into its components red, green, blue and luminance. OIII emission overlaps on blue and green filters with maximum transmission to allow high efficiency and natural color imaging. Gap between green and red filters serves to block out the primary Sodium light pollution line at 589nm and improves color balance and separation.
Main Use and PerformanceWork well with debayered monochrome CCD cameras.Suitable for deepsky and planetary CCD imaging.RGB-imaging allows equal weighting factors for each channel, very important for automated imaging.The ideal raw material for image processing in the sRGB color space is available with LRGB filter set and mono CCD camera.
