Using his own pinpoint methodology to determine sight it therefore leads onto the necessary continuation where he can't trust his eyesight which have field of view.

Yes, especially if the pole star is visible in the pic. There are diagrams in the article showing roughly what patterns of trails to expect when looking in each direction for both hemispheres.
You dont need a time lapse camera, almost any will do. If you cant do long exposures you can do lots of consecutive shots and stack them together in one image to get the same result.

There are loads of guides about this on line. Get a tripod, a digital camera and put it into manual mode. Point to a bright star, zoom in on the display as much as you can and focus manually until it is as crisp (or as small) as you can get it, then return to normal zoom. Set the aperture to the lowest number, might be something like f/4.6 depending on your lens, if you have a f/1.8 or something that is really good. Set the ISO fairly low. The thing that really makes it easier is a invervalometer, basically a small gadget that will keep snapping away for you. I have one of these which is quite cheap:

I set mine to around a minute exposure (you want as many stars as you can get without looking washed out from light pollution in the sky), continual shooting and have a gap of a second or two to give the camera time to save the image. Set it going for an hour or so and go do something else.

This will give you loads of pictures of the stars. There are a few star trail stackers out there. I just realised I never reinstalled when I got a new laptop, but I think this was the one I've used before:

A few clicks and job done.

The only extra bit in the process I would say, depending on where you live, is to go through each frame and look to see if there is anything unwanted, like a passing plane. When I have had that, I've just used a photo editor (gonk) to select the background sky colour and airbrush it out, leaving as many of the stars around as possible. It will look like a bit of a naff job on the individual frame but that disappears through the stacking.

Someone in this thread previously mentioned that the curvature of the earth isn’t a parabola, but indeed a sine wave. The trails to the left and to the right of the straight line trajectory will be (unless I’m wrong) follow the same mathematical principles.

The drop over the horizon can be calculated by
h = r - r * cos(d/r)
Where h is the height of the drop, r is the radius of the planet and d is the distance along the surface you are calculating the drop to.

That gives a cosine wave and the top half of that describes a circle. (Graphing sin squared x + cos squared x gives a circle). Once you start calculating the drop on anything more than half the earth (imagine standing at the 'top' of a slice of earth like a clock and you are at 12, beyond 9 or 3 in the other direction) it starts to become meaningless because the drop is straight through the planet.

Love space and astronomy but it all baffles me the locations etc all the maths behind it.

Not my strong point maths

By definition you can't like space and astronomy because you don't understand maths and therefore are getting your info from authority. Flat Earth lad says so!

He knows the rest of us just follow narratives, and that's fine, in his words. We just go about our daily lives not needing to challenge the narrative as it's not important. We have work to do, and it doesn't matter about such things. He actually knows the truth as he's looked deeper into things because he uses pure logic to solve problems. Proper unhindered reasoning. It's 2022 and he has cracked the code after all these thousands of years, not millions as the cell doesn't live that long.

Amazing thing is though we could all do what @DaveH has done and come up with the same results 👌
Wonder why 🤔😂

the maths is offered on a plate like the global model to give you false results
