When it comes to capturing the breathtaking beauty of the cosmos, the Baader Planetarium 8.5 nm OIII CCD Filter stands out as a high-quality, innovative, and durable choice. Specifically designed for astrophotography, this filter is renowned for delivering the highest contrast deep sky images in H-Alpha, H-Beta, Oxygen III, and Sulfur-II, all while ensuring the shortest possible exposure times. The filter's ultra-narrow bandwidths boast incredibly high transmissions, effectively rejecting light pollution and blocking longer wavelengths. This results in more accurate and detailed images of celestial objects, making it a versatile tool for both amateur and professional astrophotographers. The Baader Oxygen III filters are celebrated for their high optical quality, ensuring no loss in sharpness or contrast. Each filter substrate is fine-optically polished plane parallel, delivering a smooth and accurate 1/4 wavefront over the entire surface. This level of precision sets Baader filters apart from other commercially precision-polished filter substrates. The coatings on these filters are applied using the most sophisticated 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. Moreover, the Baader coatings were meticulously developed to eliminate the annoying reflections often found in other narrowband astro-filters. This was achieved through careful design and testing of the coating stacks. The anti-reflection coatings are specifically designed to prevent halos and are balanced to prevent physical deformation of the optically flat substrates. Each filter is individually coated, permanently sealing the coating edges, to ensure 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 a long-lasting, high-quality product. In conclusion, the Baader Planetarium 8.5 nm OIII CCD Filter is a colorful, high-quality, durable, innovative, and versatile choice for anyone looking to delve into the captivating world of astrophotography.
