Technical data sheet
ZWO DB2 – 2” Duo-Band Filter for Nebula Astrophotography
The ZWO DB2 is a 2-inch Duo-Band filter designed for deep-sky astrophotography with color cameras. It selectively isolates the H-alpha (656 nm) and OIII (500 nm) emission bands, drastically improving nebula contrast even under light-polluted skies.
Key Features
- Duo-Band Hα + OIII Filter for emission nebulae.
- 2” Format compatible with EFWs and filter drawers.
- Ideal for OSC (One-Shot Color) cameras.
- Reduces light pollution.
- Increases contrast and details of nebulae.
- High-transmission multi-layer coatings.
- High-quality optical glass construction.
Higher contrast nebulae even from urban skies
The ZWO DB2 allows you to:
- Photograph nebulae even in the presence of heavy light pollution
- Reduce the impact of LED and sodium lamps
- Obtain cleaner, higher-contrast images
- Simplify post-processing
It is an ideal filter for those using color cameras who want effective results without switching to monochrome systems.
