IR Blocking


                                                                 

This filter has an extremely sharp cutoff at 690nm yet leaves all the visible red, including the important 656nm H-alpha emission line, preventing IR wavelengths from blurring fine detail in your digital images.
 
Recommended For Use With CCD, Video & WebCams for sharper images Works with any CCD camera, eyepiece, or adapter that accepts 1.25" cells.
