This ColourMagic Super D 2" Duo-narrowband filter set has a narrow bandwidth of 6nm.

The narrower bandwidth and efficient light transmission considerably enhance the contrast of your pictures, making it easier to display the details of the stars that otherwise are fairly difficult to spot.

Although they are not specifically high speed filters, the Super D Duo-narrowband filters behave well when used together with a fast telescope, even at f/1.9.

With its efficient and excellent halo control performance, as well as a fun and innovative shooting experience, this Super D filter set will become your favorite in no time!
