Baader Planetarium 160mm AstroSolar BDSF 3.8 White-Light Digital Solar Filter for Telescopes

Where precision and safety in solar observation are paramount, the Baader 160mm AstroSolar BDSF 3.8 White-Light Digital Solar Filter emerges as a superior choice for astronomers and astrophotographers alike. This high-quality filter is a product of the renowned Baader Planetarium, a leader in the production of astronomical equipment, ensuring that users receive a product that is both innovative and reliable.

Crafted with meticulous attention to detail, the Baader Digital Solar Filter is equipped with the AstroSolar PHOTO Film OD 3.8, a film that has stood the test of time and has been specifically designed for digital videography and the lucky imaging technique. This innovative film allows for the shortest exposure times, effectively "freezing" atmospheric turbulences and providing crystal-clear images of solar phenomena.

Unlike many ready-made filters that compromise image quality by stretching the filter material taut, the Baader AstroSolar filter is engineered to maintain the film's integrity. The filter must be mounted stress-free to function as a high precision plane optical window, which is why it may exhibit slight ripples - a hallmark of its exceptional design that ensures optimal performance without the distortion found in lesser quality filters.

The Baader Digital Solar Filter boasts a durable, temperature-compensated cell that prevents stress on the AstroSolar film during temperature fluctuations. This ensures that the filter maintains its superior optical quality in a wide range of temperatures, from -30°C to +50°C. The film is carefully cemented onto an injection-molded ring that matches the thermal expansion of the AstroSolar material, creating a free-floating film-carrier ring. This ring is then securely held within an aluminum frame by a fiber-reinforced plastic holding ring, providing maximum security and preventing any potential damage to the cell.

The Baader 160mm AstroSolar BDSF 3.8 White-Light Digital Solar Filter is an efficient and user-friendly solution for those seeking to capture the sun's splendor without compromising their equipment or vision. Its large 160mm filter size allows for an ample amount of light to pass through, resulting in clearer and more detailed images. Whether for professional or amateur use, this solar filter stands out as a top-tier accessory for any high-end telescope, offering both safety and unparalleled optical performance for solar digital imaging.
