Antlia Solar Discover 5Å H-alpha 656.28 nm 1.25" is a specialized solar filter designed for use in H-alpha observation systems based on etalon technology. With a central wavelength of 656.28 nm and a bandwidth of 0.5 nm (5 Å), it enables detailed observation of solar chromosphere structures when used within a proper optical system. The hard-coated design and integrated blocking filter set ensure effective suppression of out-of-band radiation.
