Earth is about 3/5ths of the way from the Center of the galaxy. ( The galactic center is in the bottom of the image.)  This image was taken using a Cannon EOS camera and a 24MM lens at F/4.5. The camera tracked perfectly on the stars for over 13 minutes via a StarSync Tracker without which the stars would have stretched into thin horizontal lines due to earth's rotation.   For more info on a StarSync Tracker go to WWW.StarSync Trackers
