For all astrophotography enthusiasts, filters are one of the indispensable accessories to achieve perfect deep-sky imaging. The dedicated astronomy filters for deep-sky imaging can effectively eliminate the influence from the background light and enhance the contract of your photographs and make the targets displayed more clearly and delicately. Askar’ s new-launched 3nm deep-sky narrowband filter set colour Magic is a professional astrophotography tool specifically designed for deep-sky imaging.
Compared with the previous Askar 5nm deep-sky filters, this filter set has a narrower bandwidth. Therefore, even if your are at an area affected by the urban light pollution, night glow and other undesired light, you can capture high-quality deep-sky pictures with the help of Askar 3nm narrowband filters. The narrower bandwidth and efficient light transmission considerably enhance the contrast of your pictures, making it easier to display the details of the stars that otherwise are fairly difficult to spot.
At the same time, the colour Magic 3nm deep-sky narrowband filter has very good halation control, providing more contribution to your astrophotography.
Askar 3nm Duo-Band Filter
Askar 3nm duo-band filter has an extremely narrow bandwidth, and an ultra-high transmittance over 88% at its center wavelength (500.7nm and 656.3nm). Askar 3nm duo-band filter 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 Askar 3nm duo-band 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 Askar 3nm duo-band filter is ideal for photographing emission nebulae, planetary nebulae or supernova remnants, and has a very high transmittance at the central wavelength. The highly narrow bandwidth of the filter effectively blocks out the effects of light pollution or other distracting factors such as night glow.
