Ok Kids...here's the deal...
You will see the stars through tiny teeny gaps in the folaige, that may not be obvious to you and on longer exposed shots because of small movements of said folaige in the breeze etc...after all the light they are shining has travelled light years across the galaxy to be ooohed and aaaaahhhhed at, so there not going to let a few leaves stop them! (O.K. I'm anthropomorphising starlight a bit here, but it's true) I have noticed similar effects on many nights out stargazing...and how do you tell planets from stars? They don't "twinkle" as much and travel mainly along the path of the ecliptic (the path the sun and moon travel)
P.S. Lovely photo James!
