642 IR Pass Filters

Astronomik’s IR pass filters from their ProPlanet 642 series are exceptional filters for not only astrophotographers capturing deep sky objects in H-alpha regions, but also daytime IR photographers and lunar/planetary imaging. With a wide range of sizes and mount styles, there’s a ProPlanet filter for every type of camera.

Astronomik is a well-known maker of affordable, reliable filters for astronomy. The company was founded on the principle that everyone should have access to high-quality filters, and it has never strayed from this philosophy. The ProPlanet series is just the latest in a long line of filters that have surpassed expectations.
