The lovely, weird-looking, globular cluster Messier 4, lies about 1½° West of Antares. Notice the bright bar of stars running through the centre of the cluster.

George used a Canon EOS350D mounted at the prime focus of a Meade LX90 SCT 8-inch f/10. With the ISO set to 400, he took six 5-minute exposures, "guided off-axis with a Meade LPI and my trusty laptop from the city of Rustenburg."

"I figure it is probably best to take photos of clusters from town and the fainter subtle stuff under dark skies," George writes, after recently showing vividly the effects of light pollution on long-exposure photos.
