Moon - 19.8.2021 at 22.54 Helsinki Observation number 100665

Visibility IV / V

Surprisingly, the sky became clearer and the Moon, which grew by almost 87 percent, shone between the clouds. The second image is a composite image: with normal exposure, the Moon would only appear as a bright bright dial. That’s why I stacked two images - a deliberately less exposed number one image with the Moon’s dark spots and craters clearly visible, and an image where the exposure mostly highlighted the clouds. In this way, the human eye sees the situation, that is, it corrects the "overexposure" of the Moon; the camera can only illuminate according to either the clouds or the bright moon. I hope I was able to explain my views in an understandable way.
