Mushroom like thing

I was all excited on my way home. Inspired by a couple that I subscribe to - one of whom did a lovely moon shot yesterday, and another who did a picture of Uranus, I was all excited at the blue sky thinking I could use my 400mm bad boy to try and get a picture of Jupiter and see if any of the Gallileon moons were going to be visible.

Answer is none as the sky has completely clouded over. So a dull (in comparison), mushroomy blip
