Orion 2" LRGB Astrophotography Filter Set

The Orion 2" LRGB (Luminance / IR cutoff, Red, Green and Blue) Astrophotography Filter Set is useful for a variety of imaging systems including larger format CCDs. These specialized filters are designed for creating high-quality composite color astrophotos of with monochrome imaging cameras. Combining separate images taken through these four filters with a monochrome CCD provides a higher resolution final image with better color rendition than an image from a comparably sized color CCD.

The 2" LRGB filter set features robust dichroic glass filters designed for maximum light transmission. The color filters have a IR (infrared) and UV (ultraviolet) blocking coating and all filters are parfocal to eliminate the tedious task of refocusing between exposure sets.
