Colour Magic Super D1 Duo Narrowband Filter (OIII&Hα)
Category： Askar
Askar newly launched ColourMagic Super D 2" Duo-narrowband filter, is a professional astrophotography tool specifically designed for deep-sky imaging. The Super D filter, as the name suggests, has the "Super" halo control capability. During the filter research and development process, we made a special design optimization for Super D. And in the end, it becomes a special filter with one bandwidth at 6nm and the other bandwidth outside 6nm.

ColourMagic Super D1 Duo-narrowband filter (OⅢ+Hα) has an ultra-high transmittance over 85% at its center wavelength (500.7nm and 656.3nm). It can effectively enhance the contrast of your pictures, making it easier to display the details of the stars that otherwise are fairly difficult to spot. In areas with very serious light pollution, this filter can also selectively filter light pollution and cluttered signals through the emission lights of the nebula to achieve the ideal shooting effect.
Although it is not a specific high speed filter, through our real test, the Super D Duo-narrowband filter behaves well when using together with a fast telescope even at f/1.9.
