ZWO LRGB 2" Filter Set (2 inch)
ZWO LRGB 2-inch Filter Set
The ZWO LRGB2 Filter Set includes four 2” mounted astrophotography filters that pass red, green, and blue bands of light as well the full luminance spectrum across the visible band.
By taking individual images with each of these filters and a monochrome astronomy camera and combining the separate images with standard processing techniques, you can create beautiful correct-color images of planets and deep-sky objects.
The new ZWO 2″ LRGB Filters have great performance in transmission, also they have excellent coatings producing good color separation.
