But, when I point my 1 watt expanded 520nm green or blue (@4 W) at a high cloud base, I can clearly see a bright spot, so I guess this means someone viewing the spot from a mile or more away will likely only see the spot moving around on the cloud? How cool - That might get some people scratching their heads.
Also I saw a vid a few years ago from a news station on here of "footage of a ufo"? Everyone on here knew it was a 445. It was the beam going up to the clouds.
:crackup::crackup::crackup: I bet that has happened many times, even in the middle of the night you know there is going to be someone else outside somewhere that can see that spot on the clouds, if they aren't laser hobbyists like us they are going to think UFO.:crackup:
Ok I have the 1 watt 520nm diode set up in a massive heat sink with a plug in power supply. Twice in different locations I set the laser pointing straight up and walked away until I could not see it any more. Both times I got about a half mile (measured by google maps) though at that point it was so dim that I had to look straight at where it was and pan my eyes up and down to catch a glimpse. With light pollution it really is not drawing attention past a few hundred meters and is impossible to see over a half mile. I am wondering how much more visible it would be in the middle of nowhere.
i wonder what my 3 watt 445 would do... But I don't want a fake ufo sighting...there's a reason for that guys and its NOT attracting attention it's something else.let's say i was in the right place twice at the right time with my DSLR and 20x80 binos
How's that for a simple build?
