SVBONY UHC 2" Light Pollution Filter for Nebula Observation

SVBONY UHC 2" Light Pollution Filter for Nebula Observation

Description:

The SVBONY UHC 2" filter is designed to selectively reduce the transmission of specific wavelengths of artificial light, such as those from sodium or mercury vapor lamps. This selective blocking darkens the sky background and significantly enhances the contrast of emission nebulae.

It is effective for both visual observation and astrophotography, especially under moderately light-polluted skies. Even in dark-sky locations, the filter helps increase nebular contrast. Compatible with all 2" (M48) accessories, it fits most telescopes with a 2" focuser or adapter.

Thanks to its carefully designed optics, the SVBONY UHC 2" delivers clear, high-contrast, and detailed views. It is widely regarded as an essential tool for amateurs interested in planetary, diffuse, and emission nebulae.

Technical specifications:

• Type: UHC (Ultra High Contrast) filter

• Purpose: light pollution reduction

• Diameter: 2" (M48 x 0.75)

• Selectively blocks artificial wavelengths
