Thank you all for your comments.
Mike you are right. The drawing is in fact out of Starry Night. I tried it with the drawings from Stellarium also, but it appeard to be to infantile.
I donŽt know if it was very creative, I would bet somebody did it already before me.
But anyhow it is a nice method to make images of constellations more expressive and I think it won`t be the last time I used it.
I dream of a photographic view of all constellations, which are visible at my location in that style.
Would be cool and IŽll give it a try!
