This photo shows the waxing crescent Moon, in the constellation of Gemini, and earthshine as observed from near Ottobeuren, Germany on May 26, 2020. I paid close attention to not show more than the naked eye could see. At the time I snapped the photo, the Moon was but 3-days old, the optimum time to discern earthshine -- the faint glow on the shadowed portion of the Moon caused by the reflection of sunlight from the Earth. See if you're able to detect this subtle glow after sunset this evening.
