Antlia LRGB-V Pro 50 mm Unmounted Filter Set for Professional Astrophotography

The Antlia LRGB-V Pro 50 mm Unmounted Filter Set is the ultimate choice for professional astrophotographers looking to enhance their imaging capabilities. Specifically designed for use with both CCD and CMOS monochrome cameras, these filters offer exceptional performance to capture the cosmos in stunning detail.

Each filter in this set is crafted with precision on a 2 mm thick substrate, ensuring both durability and parafocal consistency. While these filters maintain focus effectively, it's advisable to check and adjust focus every one to two hours to account for temperature changes.

The Antlia LRGB-V Pro filters are engineered to maximize the transmission of essential spectral lines for astrophotography, such as Hα, S II, and O III. The R filter achieves a remarkable 95% transmission of Hα and S II lines, while the overlapping B and G filters enhance the capture efficiency of the O III line.

These filters are not only efficient but also excel in minimizing light pollution. By separating the G and R channels, they effectively block sodium lamp emissions, allowing for clear, high-contrast imaging even in urban areas. Multi-layer anti-reflective coatings further reduce glare and halo effects.

Note: The Antlia LRGB-V Pro filters are designed exclusively for astrophotography and are not suitable for visual observations.
