Palomar Observatory is a great place to study the universe. It is also occasionally a very nice place to watch rocket launches. Tonight it is well suited for both as the skies are clear, the seeing is quite good and the USAF launched an Atlas V rocket from Vandenberg Air Force Base.
This picture shows the rocket crossing just above Orion's Belt.
This photo shows a staging event a little later. Both images were 30-second exposures taken with an Canon 5D and a 17mm lens.
