Askar Colour Magic Ultra E1 3 nm Duo Narrowband Filter (OIII&H-alpha), 2 Inch

Askar newly launched ColourMagic Ultra E1 2" Duo-narrowband Filter is a professional astrophotography tool specifically designed for deep-sky imaging. The Ultra E1 filter has, as the name suggests, the "Ultra" halo control capability. During the filter research and development process, Askar made a special design optimization for Ultra E1. And in the end, it becomes a special filter with one bandwidth at 3.7 nm and the other bandwidth of 4.0 nm.

Askar Ultra E1 duo-band filter has an extremely narrow bandwidth, and an ultra-high transmittance over 85% at the center of its wavelength ranges (656.6 nm and 500.7 nm). It can effectively eliminate the influence of light pollution. Even if you are in an area seriously affected by light pollution, the pictures taken with the ColourMagic Ultra E 2" Duo-narrowband Filter are still very good. It is so practical and efficient that you can get astronomical images of high quality with just one duo-band filter and an ordinary astronomical colour camera, but of course high quality images are also possible with monochrome cameras.

The ColourMagic Ultra E 2" Duo-narrowband Filter is ideal for photographing diffuse emission nebulae, planetary nebulae or supernova remnants. The highly narrow bandwidth of the filter effectively blocks out the effects of light pollution or other distracting factors such as night glow.
