SII 7nm Narrowband Filter SVBONY for CCD

This filter transmits a bandwidth of 7nm centered at 672nm and significantly reduces other transmissions, including the wavelengths responsible for light pollution.

Features

• Quality glass material; the SVBONY filter is made with multi-layer Schott glass using ion-assisted deposition technology to ensure scratch resistance and stability at the central wavelength or CWL.
• Robust metal frame; the SVBONY filter cell is made with lightweight yet strong metal and is CNC machined, sandblasted, anodized black, 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 enhance contrast when photographing deep-sky objects. It stands out better against the background of the night sky, allowing for details that were not previously apparent to be seen.
