Here the try to catch Uranus at the Observatory Gilching. The blue colour is good to see, but details are in floorground observation point not able. Ok this planet is also far away. To get more exact, the distance is about 2,9 billion kilometer. It would be interesting what the good old saw 1781 at the discovery of the blue gas planet.
