Details:
Convection cell walls, are composed of filaments. At 393.02nm these filaments are visible in the form of neutral iron and they conform to the convection cell walls- as they are in fact made of tiny filaments which were recently photographed at extremely high resolution . This is the basis for my theory about the 393.02nm wavelength and allowing one to document photospheric iron filaments that end up very very long.
