I am imaging JUICE at the moment and after stacking 5x 60s frames (aligned on the star field) I could see a hint of the track. As its a hazy night, that sounds like the bright end of 18th mag. Will do some proper sums tomorrow and post the picture.
Tonight it is 1.4 million miles away.
Time to break out Tycho tracker I think. Will be interested to see how far we can push things.
