Good on ya.

Thanks Lester, it was a brilliant night. Those dots aren't dots at all. It is the sphere of Io, however there is some albedo shading on it. The poles are darker than the equatorial region.

Thanks Graeme, when I read yours and Lesters comment about the dots I had to have another look to see what these dots were, it is Io but the poles are much darker, I suppose that gives the dot impression.
Each channel was captured for 40 sec's, at 30 fps. Exposures were, red channel 1/30th sec, green 1/38th sec, blue 1/30th sec. Histogram was 250.
