Askar Duo narrow band filter for deep sky astrophotography
For all astrophotographers, filters are one of the essential accessories for achieving 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. The Color Magic duo narrowband filters from Askar have been specially developed for astrophotography with modern cameras and are suitable for telescopes and camera lenses.

The larger bandwidths of 35 or 15 nm allow you to capture high-quality deep sky images with comparatively short exposure times in moderate light pollution. The contrast is significantly improved. The filter can be used with color astro cameras, DSLRs and mirrorless system cameras.

In addition, Color Magic nebula filters offer very good halo suppression, which significantly reduces annoying halos and reflections around stars.
