Default Some pics.and a strange fog effect W/1W 445nm. (pic. heavy)

I finally got around to taking some pics. of my 445nm.
Was waiting for a foggy night. I woke up at 4:30 one morning and not only was it foggy but there was a very fine mist in the air. PERFECT!
After taking the pics., I noticed a strange phenomenon in the beam. At the end of the beam there was a Q-tip looking termination of the beam. I know it had something to do with the mist but still found it quite strange. I have never seen any laser pics. with this before.

First set is on a clear night.
Hitting a tree about 200' away.




Hitting my shed about 100' away.

This one below is hitting a tree about a mile away. I'd love to had somebody over there to tell me the dot size.


Next, the foggy night. Note the "Q-tip" In a couple of the pics., you can see the beam vaporizing the mist close to the laser





And last a couple of the beam hitting my fountain. I thought it would look better, but it was too bright for the camera and washed out the patterns.

Nice pics, specially with the fog. Look forward to my own 445 build soon.

You sure the "Q-tip" ending is not just the laser hitting the cloud layer?

It is possible the clouds were that low. Look in the first fog pic., the "Q-tip looks like it is only 15-20 feet above the house. I've shot thousands of beam shots and never seen that effect before. Nor have I seen the beam terminating in such a short distance from the laser. I am going to try again the next foggy night and compare the 445nm to other wavelengths and see.
