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 newly-launched Color Magic Duo Ultra-Narrowband deep-sky filters are a professional astrophotography tool specifically designed for deep-sky imaging.
The Askar Color Magic Ultra-Narrowband filters have an extremely narrow bandwidth, and an ultra-high transmittance over 88% at its center wavelength (656.3nm). With a narrower band pass than the Askar 5nm deep-sky filters, the Color Magic Ultra-Narrowband allow you can capture high-quality deep-sky pictures, even if your are at an area affected by the urban light pollution, night glow and other undesired light. Even if you are in an area seriously affected by light pollution, the pictures taken with the Askar Color Magic Ultra-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 color camera.
