The Askar Colour Magic C2 Duo Band (SII & OIII) filter is an effective tool for capturing sky details with a color CMOS astro camera or camera. This filter reduces the harmful effects of light pollution while enhancing the contrast of deep-sky object details.
The Askar Colour Magic C2 Duo Band filter targets the SII and OIII emission lines, which are essential for observing interstellar gas nebulae and supernova remnants. The 2" size allows for easy integration into various astrophotography systems. Its advanced anti-reflective coating effectively minimizes unwanted reflections.
In the SII range, the filter operates with a 15 nm bandwidth, providing excellent performance at the 672 nm wavelength. In the OIII range, it collects information with a 35 nm bandwidth around the 500.7 nm wavelength, enabling detailed examination of planetary nebulae and other oxygen-rich objects.
- 2" size
- Over 90% light transmission
- 15 nm bandwidth in the SII (672 nm) range
- 35 nm bandwidth in the OIII (500.7 nm) range
The advantage of the filter is that, when combined with the Askar Colour Magic C1 Duo Band filter, it allows for the creation of Hubble palette-like false-color images with a color camera.
