Askar's new ColorMagic C 2" Duo-band filter is a professional astrophotography tool specifically designed for deep-sky imaging. The Color Magic C2 duo-band filter is an SII+OIII filter.
When shooting deep-sky galaxies with color cameras, a duo-band filter in the Hα +OⅢ bands is often used; whereas with a mono camera, a narrowband filter in the Hα, SⅡ, and OⅢ bands is often used, leaving users with color cameras missing one band of nebula detail. This can be compensated by using the Color Magic C Duo-band filter (SⅡ+OIII).
The Color Magic C2 Duo-band filter (SII+OIII) has a high transmittance of over 90% at its center wavelengths (500.7nm and 672nm). It can effectively improve the quality of the image by making the sky background of the image darker while maximizing the contrast throughout the image, enhancing the contrast of your pictures, and making it easier to display the details of the stars. In areas with very serious light pollution, this filter can also selectively filter light pollution and cluttered signals through the emission lights of the nebula to achieve the ideal shooting effect.
This filter has a broader passband and is a more economical alternative to Askar's "D1" filter.
Specifications:
- FWHM:
- OIII: 35nm ± 5nm
- SII: 15nm±3nm
- CWL: 500.7nm & 672nm
- Peak transmittance: 90%
- Thickness: 2 ± 0.05mm
- Barrier property: ≥OD3 @ 200-1000nm
- Surface finish: 60/40
Other Information
- Country of Manufacture: China
