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 Color Magic Duo Super-Narrowband filter is a professional astrophotography tool specifically designed for deep-sky imaging.
With the help of Askar Color Magic Super-Narrowband Filters, even if you are in an area affected by urban light pollution, night glow, or other undesired light, you can capture high-quality deep-sky pictures. The narrower bandwidth and efficient light transmission considerably enhances the contrast of your pictures, making it easier to display the details of the faint nebulosity that otherwise would be difficult to see. At the same time, the Color Magic Super-Narrowband Filters have good halation control, providing more contribution to your astrophotography.
After the 2” Super-Narrowband filter (Hα+OIII), Askar Color Magic launched the SII+OIII 2" Super-Narrowband filter, which is further convenient for astronomy enthusiasts while maintaining quality. When shooting with the 2" Super-Narrowband filters (Hα+OIII) and a color camera, users will have remarkable results.
Usually in astrophotography, the Hα signal-to-noise ratio is stronger while the OIII is relatively weak. As our two Super-Narrowband filters are Hα+OIII and SII+OIII, the combination can balance the signal-to-noise ratio of each channel when shooting, and after software processing, it can achieve the ideal result almost as well as shooting with a combination of three narrowband filters and mono camera.
We name the Hα+OIII 2" Super-Narrowband filter “D1” and the SII+OIII filter “D2”, the combination of them is Askar's latest "D" filter set. It offers a new way for color camera users to get similar results without using a mono camera and the SHO filters. The Askar D filter set offers a new option for astronomy enthusiasts and is sure to please.
