Is this a Hubble image of a distant nebula of gas and dust swirling swirling around a giant star factory? No, it's better than that, it is almost a hole in clouds over Potugal, separating an observer from Earth's lovely Moon. Here is Michael's description: Image obtained on Halloween night. The Moon was covered by a layer of clouds with a slight haze, which led to a decrease in intensity in the light of the Moon and refractive possible ice crystals that produced a diffuse lunar halo effect. To get a good exposure for both, the impressive clouds as well as the Moon, two images were taken with different apertures, processed separately and later combined. The final result is a ghostly Moon in a night of witches, well known as "Halloween" night, but I preferred to call "The Moon Halo-Win".
