Baader Planetarium 31mm Round 3.5nm Ultra-Narrowband H-alpha CCD Imaging Filter, Unmounted

Why settle for anything less than the pinnacle of astrophotography precision The 31mm Round 3.5nm Ultra-Narrowband H-alpha CCD Imaging Filter, unmounted, is a testament to the fusion of durability and high-quality innovation that Baader Planetarium is renowned for. This filter is meticulously crafted for astrophotographers who demand the utmost in image clarity and detail when capturing the elusive beauty of the cosmos.

Designed to work seamlessly with optical systems ranging from f/10 to f/3.5, this filter is a gateway to the extraordinarily narrow 3.5nm H-alpha world. It significantly enhances contrast, allowing even the faintest of stars to emerge with clarity, and provides an increased signal of the faintest nebulae details that are often lost with lesser filters. The result is a breathtaking view of the night sky, with celestial objects revealed in stunning detail.

The production of such an ultra-narrowband filter requires exceptional coating uniformity and precise control of the center-wavelength (CWL), ensuring that only the H-alpha wavelength is transmitted. This level of precision is achieved through advanced manufacturing techniques, resulting in a filter with a full width at half maximum (FWHM) that is finely tuned for astrophotography excellence.

Reliable and effective, this filter is a crucial tool for any astrophotographer looking to push the boundaries of their craft. Whether you're capturing the intricate structures of a distant nebula or the delicate tracery of a star cluster, the 31mm Round 3.5nm Ultra-Narrowband H-alpha CCD Imaging Filter ensures that your images will be imbued with the depth and detail that only true specialization can provide. Embrace the innovative technology that sets this filter apart and let your astrophotography ascend to celestial heights.
