These solar filters ensure safe and full aperture (sometimes called clear aperture) coverage, allowing maximum light to enter the telescope for optimal daytime viewing, especially in conditions of minimal atmospheric turbulence. In the presence of turbulence, a mask can be applied over the filter's end to effectively reduce the aperture.
