For all astrophotographers, filters are one of the indispensable accessories to achieve perfect deep-sky images. Nebula filters for deep-sky photography can effectively eliminate the influence of background light and improve the contrasts of your photos. Askar´s 3 nm Deep Sky Duo Narrowband Filter Colour Magic is designed specifically for astrophotography with modern cameras and is suitable for telescopes and camera lenses.
The narrow bandwidth of 3 nm allows you to capture high-quality deep-sky images even in the presence of significant light pollution or even bright moonlight. The contrast is significantly improved. The filter can be used with color astro cameras, DSLR and mirrorless system cameras.
In addition, the Colour Magic 3-nm nebula filter offers very good halo suppression, which significantly reduces annoying halos and reflections around stars.
