Narrowband SII 7nm SVBONY filter for CCD

This filter transmits a 7nm passband centered at 672nm and reduces other transmissions considerably, including wavelengths responsible for light pollution.

Characteristics

• High-quality glass material; The SVBONY filter is made with multi-layered Schott glass using ion-assisted deposition technology to ensure scratch resistance and stability on the central wavelength or CWL.
• Robust metal frame; The SVBONY filter cell is made with lightweight yet solid metal and is CNC machined, sandblasted, black anodized, and laser engraved.
• Standard 2-inch thread size; The filter cell screws directly into the 2-inch barrel of your telescope eyepiece.

The SVBONY SII-CCD 2-inch filter is designed for astrophotography and allows you to increase contrast when photographing deep-sky objects. It stands out better against the background of the night sky, allowing details that were not apparent before to be seen.
