Become an astrophotography enthusiast with the Baader Planetarium 8 nm SII CCD Filter, a top-tier accessory designed to deliver the highest contrast deep sky images in H-Alpha, H-Beta, Oxygen III, and Sulfur-II. This filter is engineered to provide the shortest exposures possible, making it an essential tool for capturing stunning celestial images.Boasting ultra-narrow bandwidths, this filter ensures extremely high transmissions, effectively rejecting light pollution and blocking longer wavelengths. The superior optical quality of the Baader Oxygen III filters ensures no compromise on sharpness or contrast, making every shot a masterpiece.Each filter substrate is fine-optically polished plane parallel, a meticulous process that guarantees a smooth and accurate 1/4 wavefront over the entire surface. This unique custom polishing operation sets Baader filters apart from the standard commercially precision-polished filter substrates commonly used by other manufacturers.The coatings on these filters are professionally applied using the most advanced equipment available, ensuring high consistency for bandpass centering and transmission. The ultra-hard ionbeam deposition guarantees that the coatings will never degrade from use or normal cleaning, offering long-lasting performance.One of the key features of the Baader coatings is their ability to eliminate the annoying reflections often found in other narrowband astro-filters. This freedom from reflections, along with excellent out of band blocking, is achieved through careful design and rigorous testing of the coating stacks.Each filter is individually coated, permanently sealing the coating edges to guarantee lifetime coating durability and uniformity. Unlike filters cut from pre-coated sheets of glass, Baader's mil-spec coatings won't degrade, peel, or flake off, ensuring the longevity of your investment.In summary, the Baader Planetarium 8 nm SII CCD Filter is a high-quality, durable, and reliable accessory for any astrophotography setup, designed to deliver exceptional image quality and performance.
