Baader Planetarium 8.5nm H-Beta CCD Filter, 50x50x3mm Unmounted Square

Bring your astrophotography to new heights with the Baader Planetarium H-Beta 8.5 nm CCD Filter, an innovative and reliable tool designed for capturing high-contrast deep sky images. This high-quality filter is specifically engineered to work with H-Alpha, H-Beta, Oxygen III, and Sulfur-II wavelengths, allowing you to achieve stunning images with shorter exposure times.

The Baader Planetarium H-Beta filter stands out with its ultra-narrow bandwidths that boast incredibly high transmissions. It effectively rejects light pollution and blocks longer wavelengths, ensuring that your astrophotography is free from unwanted interference. The filter's large 50x50x3mm size allows more light to pass through, providing a wider field of view for capturing breathtaking celestial images.

Crafted with the highest optical quality, this durable filter ensures no loss in sharpness or contrast. Each substrate is fine-optically polished plane parallel, delivering a smooth and accurate 1/4 wavefront over the entire surface. This meticulous custom polishing process sets Baader filters apart from other commercially precision-polished filter substrates.

In addition to its superior transmission properties, the Baader Planetarium H-Beta filter features carefully designed and tested coating stacks that eliminate the annoying reflections often found in other narrowband astro-filters. The anti-reflection coatings are balanced to prevent physical deformation of the optically flat substrates and designed to prevent halos, providing you with clear, reflection-free images.

The ultra-hard ionbeam deposition ensures the coatings will never degrade from use or normal cleaning. Unlike filters cut from pre-coated sheets of glass, Baader's mil-spec coatings won't degrade, peel, or flake off, as the cutting operation leaves the coating edges smooth and intact, preventing moisture penetration between the coatings and substrate.

Choose the Baader Planetarium H-Beta 8.5 nm CCD Filter for your astrophotography needs and experience the difference in quality and performance that Baader Planetarium products offer.
