The H&Y StarKeeper Night Filter is made up of glass constructed by the oxidization of the chemical Neodymium, creating a purple/blue effect that absorbs yellow sodium-vapor, mercury-vapor, and yellow light from low CRI LED’s. By absorbing this unwanted light, the contrast will be increased and stars will appear more visible and defined – giving you that “pop” when shooting into clear skies at night.
