DayStar's owner, Del Woods, began manufacturing narrow-band hydrogen-alpha solar filters more than 48 years ago. These precision filters have been used in multiple configurations by amateur and professional astronomers around the world with hydrogen-alpha as well as calcium wavelengths. Thus, DayStar gradually became the first solar filter manufacturer in the world.
