Product description
Askar Duo Narrowband Filter with 6 nm Bandwidth for Deep-Sky Astrophotography
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 6 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 6 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 b&w/mono and with color astro cameras, DSLR and mirrorless system cameras.
In addition, the Colour Magic 6-nm nebula filter offers very good halation control, which significantly reduces annoying halos and reflections around stars.
