Description:

Because H-Alpha is 656nm mainly through the high permeability of the spectrum, and 656nm spectrum of the color presented by the red-based, 300-1100nm cut-off depth to get the details of the launch nebula richer. Extremely narrow bandwidth allows only the 656nm band to pass through the filter, can effectively cut off the artificial light Na lamp and Hg lamp interference to make the transmission line through, so as to improve the nebula contrast. With CCD is better choice for deep sky photography and wide-field astrophotography.

Craftsmanship:
1. Optical high-precision double-sided polishing to ensure that the parallelism is higher than 30 ‘and high flatness 1 / 4λ, to ensure that does not affect the image quality of the image.
2. Precision double-sided optical coating, non-two-piece glue, effectively improve the transmittance and cut-off depth.
3. Electron Giun Evaporation Technology (E-Beam Giun)
4. Ion source assisted coating technology (IAD), to improve the density of the film to ensure that the filter wavelength to minimize the impact of temperature caused by the temperature drift.
5. High uniformity planetary wheel coating fixture to improve the uniformity of the filter wavelength
6. Optical equipment professional fine sandblasting and anode treatment, the box to do extinction treatment to prevent reflection
7. Laser engraving LOGO-never fades, fade
8. Metal frame, superior aviation aluminum

Features:

1. The SVBONY CLS EOS -C Filter is suitable the Camera Type: 60D/60DA, 7D Mark II, 80D/800D, 77D/70D/760D/750D/700D 650D/600D, 550D/500D, 400D, 100D/1100D/1200D/1300D. Notes, this Filter is not for EF-S camera Lens.
2. High cutoff is effective has been the light damage and other stray light interference
3. Clip filter design reduces internal reflection and color cast shift
