H&Y Magnetic Circular Filters

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, contrast will be increased and stars will appear more visible and defined – giving you that “pop” when shooting into clear skies at night.

Water and oil-resistant coating are applied to make the cleaning process effortlessly easy. As shown in the above testing results, water will dry out and become stinks on filters without water-repellent coating, while water will stay in the form of droplets and still be easy to clean after a long period of time.
