Tonight was my first chance to get a photo of the latest conjunction (I posted the earlier one a while ago). This was my best attempt, slightly cropped from the view with 40D and the 100-400L plus 1.4x extender, giving 560mm. This was 0.3s f/8 ISO1600, using mirror lock up, and with a little Lightroom 3 noise reduction. I labelled everything up, including the four Galilean satellites, tonight all on one side. I was pleased that on the original you can see the blue-green colour of Uranus. There was a thin layer of hazy cloud, responsible for the glare around Jupiter.
I thought I'd see what the 100-400+1.4x could do with Jupiter, so I took 20 shots at 1/50 f/8 ISO500 and played with them in Registax (though I'm a beginner with that). Here was the best I could get, at 200%.
