Technical data sheet
Optolong L-QEF 2” – Quad Band Filter
The Optolong 2” L-QEF filter (Quad Enhance Filter) is an advanced multi-band filter designed for color astrophotography. It selectively isolates the main H-alpha, H-beta, OIII, and SII emissions, enhancing the contrast of nebulae even under light-polluted skies.
Main Features
- Quad Band Filter (Hα, Hβ, OIII, SII).
- 2” format with standard M48 threading.
- Optimized for color cameras.
- Effective light pollution reduction.
- Ideal for emission nebulae.
Astro-imaging Performance
The L-QEF allows for high-contrast images with better color separation, enabling more effective post-processing compared to traditional broad-band filters. It is an ideal intermediate solution between L-Pro filters and extreme narrowband filters.
Recommended Use
Perfect for deep-sky color astrophotography with OSC cameras, especially on nebulae such as the North America, Veil, Rosette, Soul, and similar targets.
Compatibility
Compatible with color astronomical cameras and modified DSLR/Mirrorless cameras. Can be used on refractors, Newtonians, and RCs with 2” filter holders or filter wheels.
