- Electron beam gun evaporation with Ion-assisted deposition coating technology for durability and resistance to scratching; as well as stability on CWL (central wavelength) no deviation affected by temperature change
- Planetary rotation system offers precision and homogeneity of coatings ensuring high value on transmission of pass-band and Optical density of off band
- 90% transmission of main nebula emission lines; such as Ha 656nm;OIII 496nm&500nm;SII672nm and H-beta 486nm
- 0.1% transmission of off-band; specifically the major emission lines of artificial light pollution; such as Na 589nm;Hg 435nm and 578nm
- Urban optical filter can effectively suppress urban harmful light and improve the contrast of shooting target
Description
CLS Filter for Deep Sky Astrophotography
By selectively reducing the transmission of wavelengths of light pollutants;specifically those produced by artificial lighting including
mercury vapor lamps;both high and low pressure sodium vapor lights and the unwanted natural light caused by neutral oxygen emission in our atmosphere;such as sky glow
Compatible for Canon
Warning: this filter is not for EF-S camera lens
Type: city light suppression filter (CLS Filter)
- Material: optical glass lens; aluminum frame
- Shape: Clip-in
Aero metal material precise CNC machining sand blasting Process black anodized finish extinction treatment to prevent reflection laser engraving no fading CLS with wider pass-band than UHC and hence is more favored when observing under mild to moderate light pollution
Using Method: Together with the highly transparent in main nebula emission lines at OIII 496nm and 500nm;H-beta 486nm;NII 654nm and 658nm;H-alpha 656nm as well as SII 672nm;the filter is suitable for enhancing the contrast and getting more details for both visual and photographic purpose at sub-rural area Multi layers anti-reflection coating Non cementing optical substrate coating Ultra-thin filter cell minimize vignetting by maximize possible.
City Light Reduction Filter
Light pollution filter do not eliminate the effects of light pollution or increase the object’s brightness;
in many cases; they increase the contrast between nebula and night sky;not brightening the nebula
For Canon EOS APS-C DSLR Cameras
Please note that this CLS EOS -C filter is only available for the following models
the CLS EOS -C is suitable the camera type: EOS 60D;7D mark II, 80D;800D , 77D;70D;760D;750D;700D 650D;600D, 550D;500D, 400D, 100D;1100D;1200D;1300D
Doesn't fit for Canon T1i
Important: this filters is not designed for sun observation; do not look directly into the sun with this filter; otherwise it will burn the eyes. Full Spectrum modified cameras will need an additional IR-block-filter.
Use tips
If your camera's model is 70D, this filter may be not clip in tightly. Please pull the border to fit the camera perfectly.
