Baader Planetarium 50.4mm Round 3.5nm Ultra-Narrowband H-alpha CCD Imaging Filter, Unmounted

An exceptional tool for astrophotographers, the 50.4mm Round 3.5nm Ultra-Narrowband H-alpha CCD Imaging Filter is meticulously designed for f/10 to f/3.5 optical systems. This precision-grade enforced H-alpha filter unlocks the incredibly detailed world of 3.5nm H-alpha imaging, allowing you to capture even the faintest celestial bodies with enhanced clarity.

The filter's unique design significantly boosts contrast, enabling the detection of more signals from the most elusive nebulae details. This heightened sensitivity to faint stars and nebulae details sets this filter apart in the realm of astrophotography equipment.

The production of such an ultra-narrow filter demands exceptional coating homogeneity and high precision in the Center-wavelength (CWL). This filter meets these stringent requirements, ensuring optimal performance and consistent results. Furthermore, it maintains a high degree of precision in the Full Width Half Maximum (FWHM), a critical factor in determining the filter's bandwidth.

In summary, the 50.4mm Round 3.5nm Ultra-Narrowband H-alpha CCD Imaging Filter, Unmounted, is a superior choice for astrophotographers seeking to elevate their imaging capabilities. Its precision engineering and high-quality construction make it an indispensable tool for capturing the intricate details of the cosmos.
