CXB (formerly Astrodon) 1.25" One Shot Color Luminance Filter (UV / IR Cut)

CXB (formerly Astrodon) 1.25" One Shot Color Luminance Filter (UV / IR Cut)

Most one shot color cameras do not include blocking filters to prevent "out-of-band" light from exposing the background of the detector, reducing the over all contrast of your image.

CXB's (formerly Astrodon) One Shot Color Luminance UV/IR Cut filter blocks wavelengths shorter than 400nm and longer than 750nm and produces a significant increase in contrast and detail in your color images.

CXB (formerly Astrodon) 1.25" One Shot Color Luminance Filter (UV / IR Cut)

CXB (formerly Astrodon) 1.25" One Shot Color Luminance Filter (UV / IR Cut) is used primarily to “bracket” the color-corrected band of refracting telescopes. This filter can also be used as a “visible” filter in RGBV (red-green-blue-visible) astrophotography with reflecting telescopes.

Most digital/CCD cameras have built-in infrared filters, however an infrared filter may be used in addition depending on how far into the blue your primary lens is color-corrected. This filter blocks wavelengths shorter than about 400nm. If your camera does not have a built-in infrared filter, CXB's (formerly Astrodon)  One Shot Color Luminance UV/IR Cut filter is recommended, as it blocks all wavelengths longer than 750nm.
