The Optolong LRGB filter set is designed for maximum contrast and with extremely high gradients for clear differentiation of colors. The filters divide the spectrum into red, green, blue and luminance. 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.
31mm and 36mm filters are unmounted
