About the Astronomik MaxFR 1.25" H-alpha 6 nm CCD Filter

This Astronomik MaxFR 1.25" Round Mounted H-Alpha 6 nm CCD Filter is the optimal narrowband filter for CCD astrophotography. With a 6 nm 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.

About the Astronomik MaxFR Filter Line

This high quality line of astrophotography filters uses a built-in MFR coating technique to produce the best out-of-band blocking possible, from the ultraviolet to the infrared. The MaxFR filter line by Astronomik is manufactured using an entirely new process specifically designed for fast optical systems and focal ratios. This results in extremely high contrast with no haloing!

Please note this filter must NEVER be used for solar observing or imaging. Doing so will cause permanent damage to your eyes.
