Professional Astrophotography with ZWO 7nm Narrowband Set
The ZWO 36mm Narrowband Filter Set is essential for high-end CCD/CMOS astrophotography. By isolating specific emission lines (Ha, OIII, SII), these filters allow you to photograph nebulae even under light-polluted skies, delivering the high contrast and detail required for the famous Hubble Palette images.
What’s in the Box?
- H-Alpha (7nm): Captures the dominant red emission of star-forming regions.
- OIII (7nm): Reveals the blue-green light from planetary nebulae and supernova remnants.
- SII (7nm): Isolates the deep red sulfur emissions for complex nebula structures.
- Protection: Includes 3x individual plastic cases for safe storage.
