SVBONY Light Pollution Filter
CLS Filter 2 inch enhances the visibility of deep-sky objects like nebulae by selectively reducing the transmission of light pollution wavelengths, specifically targeting both artificial light pollution and detrimental natural light.
SvBony CLS Filter 2 inch Features:
- 90% transmission of main nebula emission lines (i.e. 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 (i.e. Na 589nm, Hg 435nmand 578nm).
- CLS filter with wider pass-band than UHC filter
2 inch Light Pollution Filter for telescope is unbeatable for revealing nebulosity, for get superb views of the M42, Lagoon, Swan and other extended nebulae.
CLS Light Pollution Filter Details
Multi-layers anti-reflection coating
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.
Aluminum alloy process
Process Black Anodized Finish Extinction Treatment to. Prevent Reflection Laser Engraving No Fading.
CLS Filter out the brightening of the sky due to artificial light. As many celestial objects, such as nebulae, radiate at other wavelengths, a considerable increase in contrast can be achieved by this.The background sky appears darker and, all at once, faint details become visible.
