Another US resident means you are in the USA, correct?
If yes, wtf are you doing posting pictures of shining the laser into the clouds? This is why I get pissed about the 445 hand held lasers! They are cool, but too many people are temped to do stupid shit with them....
Is it actually illegal in the States to point a laser up into the clouds? I thought it was o.k. for such as pointing out stars etc for astronomical purposes. I'm in the UK so i'm uncertain of US law... Can you clarify for me what is and isn't allowed with regard to astronomy? I can understand it near an airport/flightpath, but you guys have a lot of empty space out there...

Technically, in the USA if a laser beam above 5mW powers projected into navigable air space it requires FAA approval or non-objection.
"An outdoor laser light show/demonstration is considered to be a laser product by the Food and Drug Administration’s Center for Devices and Radiological Health (CDRH) and, if the irradiance is greater than 5 miliwatts per square centimeter, the demonstration requires a variance to Title 21, Code of Federal Regulations, Section 1040.11c. The variance (issued by the CDRH) requires the laser user to notify the Federal Aviation Administration (FAA) of the proposed laser operation and resolve any objections that the FAA may have."
"The FAA's safety rules and the criminal law provisions outlining interference with crewmembers are independent of any rules promulgated by the FDA. Therefore, before conducting any outdoor laser operation, a researcher must ensure all physical, procedural, and automated control measures are used to ensure no aircraft will be exposed to levels of illumination greater than the respective maximum irradiance levels established for the various protection zones. This includes any laser that is in a building but may exit the building through an opening"
Because of these ding bats with the 445 pointers (like the one posted here) and because of the jack asses pointing them up into the sky, we *PROFESSIONAL* Laserists and people trying to run their companies have to sell a kidney, fast for 30 days pray to all gods out there in every religion and petition congress to accomodate a client for an outdoor show.

Thanks Marc, that's pretty much clarifies it. However, the wording here is slightly ambiguous...
Would pointing a pointer into the sky for the purposes of stargazing constitute a "laser light show/demonstration"? Having said that I guess the 5mW clause has got it pretty much covered.

Marc beat me to it. I was going to make the following points:
1. The chance that the laser pointer is certified and varianced is less than zero.
2. The chance that there was a show report done and FAA clearance for the show is less than zero.
3. The first idiot asshole that hits a plane with a 1W 445 is going to cause all hell to break loose - and there is a very remote chance that one incident "could" jeopardize our supply of 445nm diodes. And could even worse, crash a plane. I will grant you it is a slight possibility to blind a pilot for long enough that he could not land, but it IS possible with a 1W laser. Especially at night.
I just can't understand why people don't think before they do stupid stuff....
The last picture looks to me like the lights of a city in the clouds. Almost certain that close to every city there is an airport with airplanes flying to and from it.
A swimming pool in the yard and city lights. Probably not out in the empty spaces of the USA. I think the biggest empty space around there is between willpine's ears.
