These are safe full aperture (sometimes referred as clear aperture) solar filters. This means that it allows the most light possible into the telescope because it allows the full aperture of your telescope to be viewed. The full aperture allows the best possible daytime viewing when there is minimal atmospheric turbulence.

The ZWO 7nm OIII filter is centered around the Oxygen III band of 501nm. Oxygen III or double ionised oxygen occurs at primarily at 500.7nm and secondarily 495.9nm. The highest levels of OIII are usually found in diffuse and planetary nebulae. The OIII emission lines were first discovered in the 1860s in spectra of planetary nebulae. OIII wavelengths relate to the green-turquoise-cyan in colour on the spectrum whilst the narrowband width makes the background space very black.
