The Moon and Da Vinci glow: Astrophotographer captures a beautiful celestial phenomenon

Astrophotographer Andrew McCarthy has published another incredibly spectacular space portrait. On it, you can see the moon of our planet and its neighbors in the sky.

McCarthy’s photo shows a half-lit moon surrounded by stars and clouds. This is a composite image. To obtain it, McCarthy used two cameras and two telescopes.

This shooting technique is explained by the fact that the Moon is many orders of magnitude brighter than the stars in the sky, and they are simply lost in its light. Therefore, two cameras are usually used to shoot such portraits. One takes pictures of the moon, and the other of the surrounding background. Then their pictures are combined into a single image.

You can also note that although the Moon is half illuminated, we can still see the outlines of its night side and the contours of the seas. This effect is sometimes called ashen glow or Da Vinci glow. It is explained by the fact that sunlight reflected from the Earth illuminates the surface of the Moon. It is best seen when the lunar disk is in the stage of a thin sickle.

Earlier, we talked about which planets can be seen next to the Moon this month.
