Optolong 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 colour imaging. Gap between green and red filters serves to block out the primary Sodium light pollution line at 589nm and improves colour balance and separation.
