The main purpose of this filter is to enhance astrophotography. It is designed to block all wavelengths of light except for the H-alpha wavelength, which is specific to the emission of hydrogen atoms in the night sky. This allows for capturing detailed images of nebulae, stars, and other celestial objects without the interference of other wavelengths of light.
The enforced contrast is achieved through the filter's design, which allows for the transmission of the H-alpha wavelength only. This results in the reduction of light pollution and enables the capture of even the faintest stars and detailed nebulae.
Central wavelength (CWL) precision refers to the accuracy with which the filter blocks all wavelengths of light except for the H-alpha wavelength. High CWL precision ensures that the filter effectively isolates the H-alpha wavelength, enhancing the clarity and detail of astrophotography images.
This filter is ideally suited for astrophotographers, whether they are professionals or hobbyists. It is designed to enhance the clarity and detail of celestial images, making it a valuable tool for anyone interested in capturing the beauty of the night sky.
This filter is unique due to its narrow 3.5nm H-alpha enforcement. This extremely narrow enforcement allows for greater contrast and detail in images, making it especially effective for capturing intricate details of nebulae and faint stars. It is also produced by Baader Planetarium, a brand renowned for its high-quality optical products.

AstroSolar film is the standard for white light solar filters. This mounting cell has two great advantages for eclipse photographers. The wide flange shades your camera avoiding overheating. The external 3 rubber bumper attachment is easy to remove and replace quickly without disturbing your aim. This is a great advantage for totality in a total solar eclipse. Highly recommended

Enhance your astrophotography experience with the Baader Planetarium 2" Round H-alpha Enforced-Narrowband 3.5nm Filter, meticulously engineered for f/10 to f/3.5 optical systems. This high-quality, durable filter is your gateway to the incredibly narrow 3.5nm H-alpha world, allowing you to delve into the cosmos with unprecedented clarity.
Crafted with innovative technology, this filter dramatically boosts contrast, enabling the capture of even the faintest stars and revealing more intricate details of the most elusive nebulae. Its effectiveness is rooted in the stringent manufacturing process that demands extreme coating homogeneity and exceptional central wavelength (CWL) precision, ensuring that only the H-alpha wavelength is transmitted, while all other wavelengths are blocked.
The enforced contrast achieved through this filter's design results in astrophotography images that are not only more detailed but also more reliable, as it significantly reduces the impact of light pollution. This makes it an indispensable tool for astrophotographers seeking to document the beauty of the night sky in its purest form.
The initial production of these innovative filters has focused on the most essential sizes, including the 2" / 50.4 mm round and 50x50 mm square formats, with additional sizes anticipated to meet the needs of various optical systems. With a full width at half maximum (FWHM) that defines the precision of this filter, astrophotographers can trust in the consistent performance and quality that Baader Planetarium is renowned for.
Choose the Baader Planetarium 2" Round H-alpha Enforced-Narrowband 3.5nm Filter for a transformative astrophotography experience, capturing celestial wonders with unparalleled detail and clarity.
