The Askar Duo Narrowband Filter with a 6 nm bandwidth is an essential accessory for deep-sky astrophotography, designed to enhance image quality by reducing background light and increasing contrast. Perfect for capturing nebulae and galaxies, this filter is compatible with modern cameras, telescopes, and camera lenses. Its narrow 6 nm bandwidth allows astrophotographers to achieve high-quality images even in light-polluted areas or under bright moonlight. Suitable for both mono and color astro cameras, as well as DSLR and mirrorless cameras, it ensures versatility and outstanding performance.

 

The Colour Magic 6-nm filter also features excellent halation control, minimizing halos and reflections around stars for crisp, detailed images. This makes it an ideal choice for astrophotographers seeking professional-grade results.
