Compared to 3nm CaK, it is also very excellent on the upper surface of the chromosphere. Significantly better than the surface on a 3nm optical sphere layer. - It is worth noting that due to the low sensitivity of the eyes to CaK frequency, the bandpass of CaK (393nm) makes it almost impossible for the human eye to see the characteristics of the sun.
