Astronomik H-alpha 6nm CCD MFR – 36mm Round

This Astronomik MaxFR 36mm Round Mounted H-alpha 6nm CCD Filter is the optimal narrowband filter for CCD astrophotography. With a 6nm FWHM, this parfocal filter is ideal for standard CCD cameras, allowing very fast optics to be employed.

The contrast between objects with H-alpha emission lines and the skyglow background is greatly enhanced by the Astronomik MaxFR H-alpha CCD Filter. In addition, this filter completely cuts off light from spurious sources such as the mercury and sodium-vapor lines from street lamps, making it an outstanding light pollution filter! Due to the Astronomik CCD H-alpha substrate’s high optical quality, you’ll see the same razor sharp stars you’d see if you were using your regular telescope.

• Designed for fast optical systems.
• MaxFR coating allows use down to focal ratio of f/2.
• High contrast without halos.
