The LRGB filter set is designed for maximum contrast and has extremely high gradients for clear differentiation of colors. The LRGB filter set divides the spectrum into Red, Green, Blue and Luminance (UV/IR cut). OIII emission overlaps on blue and green filters with maximum transmission to allow high efficiency and natural color imaging. The gap between green and red filters serves to block out the primary Sodium light pollution line at 589nm and improves color balance and separation.
WARNING: iOptron filters are not designed for direct solar observation. NEVER use these filters for observing or imaging the Sun, or permanent eye and equipment damage will result.
