Description
CCD OR DSLR CAMERAS MAY ALSO BE SENSITIVE IN THE INFRARED AND ULTRAVIOLET SPECTRUM. THIS MAY BE A CHROME BALANCE PROBLEM IN COLOR CAMERA Astrophotography, WHICH IS SOLVED BY USING A UV/IR BLOCKING FILTER.
BESIDES THE COLOR BALANCE, THE UV/IR BLOCK FILTER ALSO IMPROVES THE IMAGE REPRODUCTION CHARACTERISTICS WITH LENS SYSTEMS (FOR EXAMPLE REFRACTOR). THESE SYSTEMS ARE OPTIMIZED FOR THE WAVELENGTHS OF VISIBLE LIGHT, BUT IN THE UV/IR FIELD THE MORE SENSITIVE AREA REPORT A HALO AROUND THE STAR. ALSO THIS INCONVENIENCE IS ELIMINATED BY THE BLOCK FILTER.
ALSO, IT'S PERFECT FOR SOLAR OBSERVING TOO. THESE SHOULD ONLY BE CONDUCTED THROUGH A PROPER PROTECTIVE FILTER OR HERSCHEL PRISM, BUT THE ADDITIONAL BLOCKING OF HARMFUL UV RAYS IS VERY APPRECIABLE.
