:shrug:Hard to say , they are either a shadow transit ( bottom left ) its nice and round , impact marks ( top right ) its irregular in shape ? or most likely dust on your camera lense .
Nice photo , what did you use to get this image ?

Wonderful image Sebastion. The spots are the shadows of Europa and Io. You also captured Io itself, in the vicinity of the Europa shadow (the leftmost one) but it has fairly low contrast against the disk and cannot quite be distinguished. And Europa is there to the left of the planet. http://www.skyandtelescope.com/observing/objects/javascript/jupiter#

Thanks guys, I didn't think it was dust in the train because it moved with the planet. I used dmk21 au04. TV 2x barlow and shorty 2x barlow 8' newt. The spot nearest the equator rotated against jupiters rotation. thanks again
