H-alpha 6nm CCD MaxFR Clip-Filter Sony Alpha 7

The Astronomik H-alpha 6nm CCD MaxFR Clip-Filter for Sony Alpha 7 is a premium narrowband filter engineered for deep-sky imaging of hydrogen-rich emission nebulae. Featuring the MaxFR coating designed for fast optical systems, this filter provides unlimited usability from f/2.2 to f/6 with excellent transmission performance, making it ideal for both light-polluted urban sites and dark skies. With a narrow 6nm bandwidth, it achieves superior contrast by isolating H-alpha emissions at 656nm while effectively blocking light pollution and minimizing background stars, allowing for crisp, high-contrast images of objects like the Orion Nebula and Rosette Nebula.
