Jupiters moons

Shot using a 70-200mm lens plus x2 extender on a Canon 7D camera, I was very surprised to see that the moons could be seen beside Jupiter this morning using this setup. (cropped image)

Form my own experience can tell your nothing like a discovery like this (mine came with a simple bino) and lucky you, you got them moons in a very nice phase and formation.
Now if you felt that way, just think how Galileo must have felt the same exact experience, many years back on a January like this only some 400 years back, around 1610. Considering tools no way as refine as your!
Keep up the good work but be careful. This habit is contagious and can cost you significantly, in no time!

Thanks Samsen. I can see how Galileo would have got excited.
