Reflections of Venus
Here is my image of Venus reflecting off the sea (as always click to enlarge). The track of Venus was quite clear, but unlike last night there was no fireworks to go with it. The image was taken with my Canon IXUS at 9:40 pm ACDST (about 1 hour 15 minutes after sunset), from a height of about 10 meters looking down to the sea. Exposure time was 10 second at ISO 400 (Focal lenght 6.2 mm apature 2.8). Venus is at near maximum brightness (Magnitude -4.5), and at a sufficent height above the sea for it to remain visible after nautical twighligh a a decent distance above the sea, but not too high (10 degrees in this case). In the next few days the waxing Moon will drwon out Venus's refelection so try and see it if you can.
Other people have done better photos, see this one here.
