Baader Planetarium 1.25" Round 3.5nm Ultra-Narrowband H-alpha CCD Imaging Filter with LPFC Mount

When capturing the ethereal beauty of the cosmos, the 1.25" Round 3.5nm Ultra-Narrowband H-alpha CCD Imaging Filter with LPFC Mount from Baader Planetarium stands as an indispensable tool for the discerning astrophotographer. This high-quality, durable filter is precision-engineered for optical systems ranging from f/10 to f/3.5, ensuring compatibility with a wide array of telescopes.

Delving into the extremely narrow 3.5nm H-alpha world, this filter is an exemplar of innovation, opening up new possibilities for imaging the night sky. It effectively isolates the H-alpha spectral line, which is essential for capturing the vibrant red hues of emission nebulae and other astronomical phenomena. The result is a dramatic increase in contrast that brings out even the faintest stars and the most delicate details of nebulae, often lost in broader spectrum captures.

The reliable performance of this filter is a testament to Baader Planetarium's commitment to excellence. The production of such an ultra-narrowband filter demands extreme coating homogeneity and very high center-wavelength (CWL) precision. These stringent requirements are met and exceeded, ensuring that each filter provides the full width at half maximum (FWHM) necessary for professional-level astrophotography.

Astrophotographers seeking to elevate their work will find this filter's effective suppression of light pollution and background skyglow invaluable. The LPFC mount adds to the filter's robustness, ensuring a secure and stable connection to your imaging setup.

In summary, the 1.25" Round 3.5nm Ultra-Narrowband H-alpha CCD Imaging Filter with LPFC Mount is a testament to Baader Planetarium's innovative approach to astrophotography equipment. It is an effective, reliable, and durable choice for those looking to capture the night sky with unparalleled clarity and detail.
