L-Synergy SII/OIII 7nm Dual Band Filter – High Efficiency and Light Pollution Suppression
The L-Synergy SII/OIII 7nm Dual Band Filter by Optolong is designed for deep-sky astrophotography with both color and monochrome cameras. Thanks to its dual-peak 7nm passband centered on Sulfur II (SII) and Oxygen III (OIII) emissions, it offers exceptional contrast even under skies affected by light pollution. The high-efficiency multi-layer coating ensures over 90% transmission, blocking major artificial light sources and enhancing the color rendition of emission nebulae.
- Dual Band filter centered on SII (672 nm) and OIII (500 nm) emission lines
- 7nm bandwidth – perfect balance between contrast and brightness
- Multi-layer coating with >90% transmission
- Effectively blocks city glow and light pollution
- Ideal for deep-sky astrophotography with one-shot color (OSC) or monochrome cameras
- Made of high-quality optical glass, polished and individually tested
- Anti-reflection and anti-halo treatment for artifact-free images
- Compatible with f/4–f/10 telescopes and CMOS/CCD cameras
