This ZWO LRGB Filter set comes with four 1.25" filters that offers better coatings, separates colours and better transmission. The ZWO 1.25-Inch LRGB Filter Set is designed to enhance monochrome astrophotography by separating light into luminance (L), red (R), green (G), and blue (B) components. These filters allow precise color reproduction and improved image quality by transmitting specific wavelengths and blocking unwanted light.

Each filter features over 92% transmission at passband, ensuring bright and clear images while minimising light loss. They are optimised with multi-layer anti-reflection coatings to reduce ghosting and flare. The filters include an IR cut-off at 700-1100nm to eliminate infrared interference and are designed to be parfocal, requiring minimal focus adjustment during filter changes.

ZWO LRGB Set features:

• Schott substrate material
• Glass thickness 1.1mm
• Fine-optically polished to ensure accurate 1/4 wavefront
• 90% transmission at passband
• Infrared wavelength 700-1100nm cut-off
• Precision off-band blocking
• Multi-layers anti-reflection coating
