Talking Varied exposures 100mW 650nm beamshots

At night to my eyes it appears dimly from the side, but is pretty visible and far reaching when I'm behind it. It was a fairly clear night so I took my Nikon D90 out and did some varied exposures to bring out the beam. Here are the results

I lasers secured in a tripod and clamp to ensure there are no accidents. This shot was done on bulb mode at F3.5, 18mm. ISO 2000. I did about 15 seconds of regular shot then for a second illuminated the subject with an LED head torch before releasing the shutter. That way the beam remained vibrant and the rest of the image would expose. You can tell it was windy as the lanyard has blurred.



There's a bit of light pollution from a town near me, but this is a nice image with reasonable depth of field. Focal length was 18mm, F3.5 with ISO set to I think... 1600, cable release, bulb mode for 24 seconds.



Here it is on my garden table zapping skyward on a shorter exposure.



Thank you for taking a look, I hope you liked the beamshots, hoping to do some more soon!!

Hey Aardvark,
Nice shots! Since I never really hand hold my lasers , I took off all of the lanyards as they would always get in the way, or like you, outdoors in the wind moving around.

Thank you That is true Brucemir, however this one is the weakest and least visible of my lasers, and I like to take out and hold it by hand. There is a crazy sounding story to it, it's got an unusual use I'm a bit nutty when you get to know me
