MRC StarKeeper | Night Filter

More visible and defined stars by H&Y StarKeeper

Photographer: Dibyendu Das


The H&Y StarKeeper 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.

Get Tough with Corning® Gorilla® Glass

At the very heart of H&Y filters, we have taken our manufacturing process to the toughest level by incorporating technology from Corning®. The glass we use is Gorilla® Glass 3 which is not only chemically strengthened — its atomic configuration is formulated so that the glass is more durable. Corning® Gorilla® Glass 3 is fundamentally tougher and more damage resistant even before chemical strengthening. And yet, how tough is it? Gorilla® Glass 3 enables improved damage resistance and toughness compared to previous Gorilla glass compositions. This is a unique feature of Gorilla® Glass 3. Something Corning is able to provide due to a proprietary glass composition that is better able to resist the deep scratches that cause glass to break.

Once you experienced the magnetic convenience, NEVER will you miss your old slot-in system again.
