The structure of the chromosphere is studied primarily using filtergrams. Filtergrams are images of the sun taken through a filter that lets in a very narrow wavelength band of light, such as light emitted by the Hydrogen-alpha transition.
chromosphere
Photosphere, Chromosphere, and Corona.
The photosphere comes first, followed by the chromosphere and then the corona. The photosphere is the Sun's visible surface, the chromosphere is the middle layer above the photosphere, and the corona is the outermost layer extending into space.
Astronomers study celestial bodies, helio astronomers specifically study suns.
The three layers of the Sun's atmosphere are the photosphere, the chromosphere, and the corona. The photosphere is the visible surface where sunspots are found. The chromosphere is a thin layer above the photosphere where solar flares occur. The corona is the outermost layer of the Sun's atmosphere, extending millions of kilometers into space.

Chromosphere and corona
Considering the solar atmosphere to have three layers (photosphere, chromosphere, and corona), the "middle" would be the chromosphere.
The photosphere comes first, followed by the chromosphere and then the corona. The photosphere is the Sun's visible surface, the chromosphere is the middle layer above the photosphere, and the corona is the outermost layer extending into space.
Chromosphere A + LS.
The sun's atmosphere includes the photosphere, the chromosphere, and the corona.
