Sun and Moon... and Mercury

The sun comes out during the day and the moon at night... well, not quite. Here is a picture I took of the moon late one afternoon. The colour of the sky and that of the moon are continuous with each other giving an interesting transparency effect. On another occasion, I took a photograph of the sun (using, of course, appropriate filters and precautions). I did so to catch the transit of Mercury on 9th May last year. It can be seen as the tidy dot in the lower left quadrant.
