Colour Magic 2" Duo-Narrowband 6nm D

The Askar Colour Magic 2" Duo-Narrowband 6nm D filter is a professional narrowband imaging tool designed for deep-sky astrophotography with one-shot color cameras. This dual-band filter combines advanced optics with exceptional halo control to capture hydrogen-alpha and oxygen-III (OIII) or sulfur-II and oxygen-III wavelengths simultaneously, enabling astronomers to achieve full SHO (Sulfur II, Hydrogen-alpha, Oxygen III) imaging results comparable to traditional mono camera setups with three dedicated filters. With peak transmittance of 85% and precise bandpass isolation, the filter excels at revealing intricate nebula details while effectively suppressing light pollution and enhancing image contrast in urban and light-polluted skies.
