Long exposure (duh, as if any of your special effects pictures are ever anything else), put in one target for x seconds, remove, place another. Probably with a long stick.

Photoshop? Ha ha ha. Just kidding TDU. I suspect the rotating arm and 5 ground points, but you did manage to achieve quite a nice separation between the points.

Hmmm.... I think I took an ordinary photo once. No, maybe I imagined it. I don't do sticks.

Correct. And where was I standing to take the picture?

Correct. I used my "skycam" suspended about 17 feet in the air ie 10 feet above the TC using a wide angle lens. It is in a custom support which is rain/sun/EMF resistant yet able to pass IR from the font to allow the long distance remote control to work. Also the flash can be used.
I turn the camera on and prefocus at 10 feet and set exposure for 15 seconds. Then it is assembled and screwed/fastened in position. Once it is lofted up, I get a torch and look at the multiple lens reflections to get the exact aim. I did also have balancing rods/level markers as well. There is a separate fine fishing line from one of the balancing rods to provide damping and reduce swinging. It is attached at right angles to a fixed ground object (my control box).
The TC is run in a normal vertical position. Around it I have 5 x 6 foot earthed vertical rods which protrude roughly level with my short rotating breakout point. The gap from breakout point to rotating rod is only about 2 feet in the top photo and I think 3 feet in the bottom. I couldn't have it too wide or the camera won't fit it in.
The third picture has me on the ground looking up. Everything except the sparks are blurred because there was wind moving the camera - even at 10pm when I had my final shot. Hence the round toroid and the circle of the breakout points are odd shapes.
This hasn't been as star shaped as I would have liked. I could have done a horizontal setup much more easily but wanted to get some experience with the elevated camera. A windless night is a requirement. So on to further planning for an Xmas tree in sparks.....
