The L-Pro Astrophotography filter is a filter for improving the contrast of deep-sky objects and dampening the sky background.

• blocks UV and IR (700 - 1100 nm)
• high transmission at passband
• improved color balance for DSLRs and One-Shot Color Astro Cameras, e.g. ASI Color Cameras cooled or uncooled by ZWO.
• high optical quality
• in 1.25" filter cell
• The L-Pro Nebula filter permits roughly 3x longer exposure times than without a filter and therefore improves contrast significantly.

This dual band filter is designed to drastically reduce the effect of light pollution, it isolates the nebulae´s emissions into H-Alpha (red) and OIII (green-blue) and blocks light pollution.

• Transmits the main nebula lines at 656.3 nm and 500.7 nm with 3 nm bandpass
• Blocks light pollution and skyglow
• Designed mainly for astrophotography
• Especially suited for color cameras
• Ideal for urban areas with extreme light pollution
• Incorporates UV/IR cut filter
• Multi layers anti reflection coating
• Ultra thin filter cell maximises compatibility with filter wheels
