Filter Built-in Light Pollution Suppression

Product information:

The CLS EOS-C is compatible with the following camera types: 7D Mark II, 80D/800D, 77D/70D/760D/750D/700D 650D/600D, 550D/500D, 400D, 100D/1100D/1200D/1300D.
Note: This filter does not work with EF-S camera lenses.

Features:
1. Multilayer anti-reflection film
2. Non-cement optical substrate coating
3. Electron beam gun evaporation technology with ion-assisted deposition coating technology, with durability and scratch resistance, as well as stability on CWL (center wavelength), which is not affected by temperature changes.
4. The planetary rotation system provides the accuracy and uniformity of the coating, ensuring the high-pass band transmission rate and the out-of-band optical density value.
5. Ultra-thin filter, by minimizing vignetting
6. Precision CNC machining sandblasting of aviation metal materials
7. Matte treatment with black anodizing treatment
8. Anti-reflection laser engraving does not fade
9. 90% transmittance of major nebula emission lines (i.e. Ha 656nm, OIII 496nm & 500nm, SII 672nm and H-beta 486nm).
10. 0.1% of out-of-band transmission, especially the main emission lines of artificial light pollution (ie Na 589nm, Hg 435nm and 578nm).
11. Suitable for color CCD cameras and unmodified DSLRs
12. CLS has a wider passband than UHC and is therefore preferred when observed under mild to moderate light pollution.
13. Light pollution filters do not remove the effects of light pollution or increase the brightness of objects. In many cases, they increase the contrast between the nebula and the night sky without brightening the nebula.
14. WARNING: SVBONY's filter is not designed for solar viewing. Do not use the SVBONY filter to look at the sun. If you don't follow the warnings, you will be blinded.
