Agena Astro affiliate Cuiv the Lazy Geek recently made this Askar Color Magic filter review:
Askar's new ColorMagic C 2" Duo-band filter is a professional astrophotography tool specifically designed for deep-sky imaging. The ColorMagic C1 duo-band filter is a dual Ha+OIII filter.
The Color Magic C1 Duo-band filter (Hα+OIII) has a high transmittance of over 90% at its center wavelengths (500.7nm and 656.6nm). 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
- Ha: 15nm ± 3nm
- CWL: 500.7nm & 656.6nm
- Peak transmittance: 90%
- Thickness: 2 ± 0.05mm
- Barrier property: ≥OD3 @ 200-1000nm
- Surface finish: 60/40
