Mercury Setting in Volcanic Sunset.
The accompanying montage of Mercury approaching the horizon and setting on 1st August was prepared from 4 still photographs selected from a time-lapse sequence of 54 taken between 6.23 and 6.27 pm using a tripod-mounted Panasonic Lumix DMC-TZ60 compact camera in manual exposure mode. Light levels were too low to record video.
