Description

Askar ColourMagic E1 ULTRA Duo-Band Narrowband Filter

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, as the name suggests, has the "Ultra" halo control capability. During the filter research and development process, we made a special design optimization for Ultra E1. And in the end, it becomes a special filter with one bandwidth at 3nm and the other bandwidth outside 3nm. These filters are extremely efficient because astrophotographers don’t need to purchase a filter wheel or a whole narrowband filter set. And imagers don’t have to buy a monochrome astronomy camera as the duo-band narrowband filter goes well with ordinary colour cameras. So the duo-band filter is an economical admission ticket for astrophotography lovers into the world of narrowband technology and deep-sky object imaging.

Askar Ultra E1 duo-band filter has an extremely narrow bandwidth, and an ultra-high transmittance over 85% at its centre wavelength (500.7nm and 656.6nm). 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.

The ColourMagic Ultra E 2” Duo-narrowband Filter is ideal for photographing 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.
