[Utah-astronomy] Comparison of green laser pointer and car headlight

Back in January 2005 when this was a hot topic, I took some photos comparing the brightness of a green laser pointer and a car headlight at 500ft (152 meters) and 1000ft (304 meters) and observed the brightness of the beam out to approximately 1300ft (396 meters). Just got around to typing up my notes and posting the pictures. http://members.csolutions.net/fisherka/astronote/observed/Glptst/index.html Hope this provides a useful collection of references.
