Since 2014, we were conducting comparative studies on the brightness of Milky Way in all skies using digital cameras equipped with diagonal fisheye lenses. In the last year, considering the influence of atmospheric light reduction near the surface of the earth, although incorporating a correction formula, the Milky Way’s magnitude does not have the same value every second number, etc. still have problems. To solve them, we made the hypothesis that the reference star for grading conversion was incorrect to examine the reference star and the photometry method.
