Courthouse Stars

Here is my first attempt at night photography.  The Shot is of Courthouse rock in Arches National Park.  Before I headed to Utah, I did some goggleing  on Night Photography (Astrophotography) and had acquired some of the basic info.
What made this shot so "Lucky" was that while I knew had to set the camera in order to capture the stars,  the rock itself was being lit by passing cars passing by on the roadside.  Also lucky was the capture of a faint Milk Way just behind.
