ZWO 36mm LRGB Filter Set

The ZWO 36mm LRGB Filter Set includes four 36mm unmounted LRGB filters. Red, Green, Blue, and Luminance. They are a great match for the ZWO five-position color filter wheel. The filters have high transmission (over 90%), are anti-reflection coated on both sides and have IR-Cut built-in.

The ZWO LRGB 36mm filter has better transmission, better coating, better color separation the RGB color combine weights will be approximately 1:1:1
