รายละเอียด
ฟิลเตอร์ลดแสงรบกวน SVBONY CLS Light Pollution Broadband Filters, 2"
- Designed to improve visibility of various Deepsky objects
- Selectively reduce transmission of wavelengths of light pollutants, specifically those produced by artificial lightings including mercury vapor lamps, both high & low pressure sodium vapor lights and the unwanted natural light caused by neutral oxygen emission in our atmosphere (i.e. skyglow)
- Together with 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), Svbony CLS filter is suitable for enhancing contrast and details for both visual and photographic purpose at sub-rural area
- Do not eliminate 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
