HOW TO BUILD A LASER POINTER FOR POINTING OUT STARS/PLANETS? Answered
I keep seeing DIY plans for "Burning Lasers" are these the same as the red or green
Lasers used to point into the night sky at selected stars,planets etc??
Can anyone direct me to info on this type of Laser? I don't want to burn anything.
Just a very strong beam that will point out objects in the night sky.
