I have a 5mw green pointer and 1.7w+- 445nm pointer. When I shine them both into the night sky they both seem to go on until a certain point. The point is the same with the both of them. How far is it?
I have a theory that its the intersection of a straight line from my eye versus a straight line from my hand but that doesnt seem correct because the distance seems the same when I mount it in a tripod.
I am sure there is some scientific name for this and explanation
