Sky Safari. It has been a while. The rains are moving in now and are very welcome. Some sky Safari tips. The large (bottom) and small (upper) Magellanic clouds are actually companion galaxies orbiting our own on something insane like a 4 billion years orbit. We will round the crazy figures up and call them both about 200,000 light years away. Neighbors in space terms as far as other galaxies go. And the crazy thing is that under dark skies on safari here in Zambia they can be seen with the naked eye. As always, let your eyes adjust and after dinner look South. Use averted vision (so look away a little bit) and you will see two faint but obvious smudges.
If you want to photograph them then the widest and fastest lens is what to use. F2.8 will work. Set your focus to manual and try and get to infinity (point at a super bright object - Venus is low in the west - and rotate your focus ring until it is as small as you can get it. Don't touch the focus and point south again. The camera must be on a tripod. Go to iso 1600 or even higher and try for say 20s exposures. It's not that hard. Congratulations, you have just photographed another galaxy. Or two. And if you pick up a faint smudge or two remember that until Edwin Hubble in 1926 we didn't even know there were other galaxies out there.
