Coronado Telescopes has been developing ultra-narrowband filters and technologies for the professional astrology market for over forty years. The most effective method of viewing the sun is by isolating the Hydrogen-Alpha wavelength at 656.3nm and rejecting all other types of light. At this wavelength you are able to view all the features of the chromosphere, which originates just above the photosphere. These features include flares, prominences, filaments, spiculae, faculae, and active regions. Coronado Telescopes have used this technology to provide innovative optics for the amateur and professional solar observer.
