These solar filters ensure safe observation of the Sun, offering full aperture (also known as clear aperture) coverage. This design maximizes light intake into your telescope by permitting the complete aperture to be visible. Optimal for daytime viewing under minimal atmospheric disturbance, they include a mask feature for reducing aperture size in turbulent conditions.
