Moonbows
The sky was clear at last, I set up "Don" the 8" scope for some some sky gazing. Of course by the time everything was set up, the sky had clouded over.There was a bonus though. Moonbows, well actually they are corona. These are produced by produced by the diffraction of light by tiny cloud droplets or sometimes small ice crystals. Ironically, I had only the other day written to someone about this relatively rare phenomenon.
The top image is the Moon with an exposure of 6 seconds, you can clearly see the dirracted bands of colour. You can also see Antares and Jupiter and the stars in the head of Scorpius (click to enlarge).
In the bottom image, I tried to block the Moon itself, to get a better view of the rings. I don't think it worked so well.Labels: corona, Moon, photography
