I also own a Bogen tripod with a fluid head. (Professional tripods are usually sold with legs and head separate.

      I would never do anything like this in real life, but it would be possible for me to somehow strap a laser pointer onto my camcorder. I would then need to stand my tripod up securely and calibrate it, so the laser points at the exact middle of the image. I could do this by just pointing the whole thing at a wall, zooming in, and then fine-tuning the laser aim until it shows in the middle of my viewfinder. I could then do the same thing for a distant object, like the wall of a house several blocks away, and fine-tune the laser aim even more until the point was in the middle of the viewfinder.

      Keep in mind the whole point of a fluid tripod head is to give the operator fine pressure-sensitive control of where the camera is pointing. There are no rubber pads pushed up against metal, seizing the metal and making fine movement impossible. Fluid heads use oil cartridges and tension knobs that let you tighten or loosen, but never completely lock, the horizontal or vertical movement. If you zoom a camera way in, tighten the tension knobs, and just lay one finger on the tripod pan handle, you can see the camera v-e-r-y s-l-o-w-l-y tracking. To an outside observer you can't even tell the camera is moving, but the viewfinder shows the camera is not only moving, but it's moving smoothly at a constant rate.

Curiously, however, the Navy to this day maintains Jack's injuries never occurred. And evidence compiled by Judicial Watch suggests the Clinton Administration covered up the attack in order to avoid international conflict.

    "Jack Daly certainly deserves a medal for his injury from a hostile force," said JW President Tom Fitton. "For more than six years, the U.S. government has refused to acknowledge an attack of a U.S. serviceman in American waters."

    "Lt. Cmdr. Jack Daly (Ret.) was partially blinded by a laser attack. The laser was fired at Daly from the Russian spy ship Kapitan Man in April, 1997, while Daly was on an official reconnaissance mission, flying over the Straits of Juan de Fuca, Puget Sound, WA. During his surveillance, which took place aboard a Canadian military helicopter, Daly felt a flash of brilliant light strike his eyes, causing him to turn away. Later in the day he would experience stinging in his eyes and sharp pains in his head. The next morning he awoke with a small pool of blood in one of his eyes.

    Military doctors told Daly that he and his Canadian chopper pilot, Captain Pat Barnes (Ret.), had been shot at with a laser by the Russians. The damage would be permanent.

    Rather than standing by their injured military official, however, Clinton Administration officials treated the incident as an inconvenient stumbling block on the path to improved relations with the Russian government and covered it up.

    The Kapitan Man was not searched until several days later and only after at least 10 hours advanced warning given to the Russians. Though a thorough search should have taken 2-3 days, U.S. inspectors were aboard for less than 4 hours. Predictably, no evidence was found.

That alone would be quite difficult, since it'll need to be capable of making really tiny and precise adjustments. The second one is that it needs some kind of very precise system that would keep it pointing to a moving target. The minimum would be some kind of very good motorized telescope mount, controlled by a computer.

First of all you have the atmosphere, with all the air and crap floating in it. Second, as the beam spreads it will become a lot less powerful. If the radius of the laser beam doubles, the area becomes 4 times larger. Either your laser has to be insanely powerful to overcome this, or you have to have an insanely good mount and tracking system. And neither of those things looks cheap, easy to get, or move around.
