It's actually worse than that. On a flat earth, even if you were pointed straight up, the mount still wouldn't work, because (according to all the common explanations of how the sky works in a flat earth model) the stars are supposedly all relatively close above us (not trillions of miles away), and they're rotating in a plane or dome around the north pole (not moving like a sphere). This means that, unless you were actually _at_ the north pole, the rotating mount would actually be rotating around _a different part of the sky_ than the stars are. You could either have the right part of the sky but the wrong axis of rotation, or the right axis of rotation, but pointed at the wrong part of the sky. You wouldn't be able to get both at the same time. A different way of looking at basically the same problem is that in a flat-earth model with a relatively close "firmament" rotating above the Earth, the stars would actually also be moving closer to you and away from you all the time as they rotated through the sky, which it's impossible to correct for by just spinning your camera like this.

Unfortunately the experiment can't be done as the earth is not flat which in part is shown by the fact that the standard polar alignment method works. Yes even in the Southern Hemisphere with the mount pointing south.

Thank you, finally someone said it! I'm an amateur astrophotographer myself and I've long said that this is all the proof you need. I have both a Celestron VFX and a Skywatcher HEQ5 Pro equatorial mount, and driving either of them with software like Stellarium, it literally lets you toggle the Alt-Az and Equatorial grids off and on and you can see the obvious difference. Simply looking at that and running through the various times of night (or day) while you plan to shoot a specific target should demonstrate to anyone how the sky operates, especially if you shoot from wildly different latitudes like me. Considering Flat Earthers advocate "doing your own research", this is a very simple and easy place to start (though, admittedly not cheap with good astrophotography gear). I suggest they go to an astronomy event so they can see it for themselves without having to layout a penny. Or hell, just download Stellarium for free, it's on every platform there is, you can even change your latitude on it to see from different vantage points.

They don’t even need the mount thingy. They can just look up and see where the stars are moving. They can also take a camera, set it still and see where the centre of rotation is for the star trails. IT’S SUCH OBVIOUS PROOF. But you just know they’re incapable of changing their mind, so they’ll twist and break everything into the weirdest shapes just to deny it doesn’t fit. It keeps getting weirder, and I love it. I hate it, but it’s intriguing how ridiculous they’ll go the longer time goes on. So I love hearing about it.

Got to visit an old observatory once. The telescope was mounted in a rig similar to that and the 'motor' was a pendulum and weights system similar to a mechanical clock (well, when you think about it, it IS a clock of sorts). The professor explained how it worked basically and how they would lock onto a small patch of sky and start the mechanism, then sit up most of the night with it. This was built something like 1912 or whatever, long before NASA and internet. Yet it worked pretty darn well (or so the professor claimed).

I have noticed that flat earthers don't have a response to any points we show them that debunks the flat earth; until someone points things out. For example they always say "water finds it's level" well no flat earther was saying anything about water droplets curving, and ocean waves curving until Professor Dave mentioned it in his vídeos. Only then they made memes saying water droplets aren't examples of water curving because they aren't the size of oceans. Well it's the same thing with the star trackers, no one was saying anything about them until you and others like Reds Rhetoric, Astronomy Live, have been showing them how they wouldn't work on a flat earther. Now there's a few flat earthers already talking about how star trackers don't work properly, or don't work beyond the horizon ect. You do great work please keep the debunking videos coming.

You can easily discount the fact that the maths then doesn’t work, and that Polaris wouldn’t be on the horizon at the equator by making up some pseudoscience word salad, possible latitude specific negative refraction coefficient, or assigning a magic refraction index to the ‘Dome’ and then mute any dissenting voices.

Dave, I hope you can continue to stay true to the course of not going down the route of so many other channels who just smirk, laugh, insinuate people are dumb, or all the other "space comma", "flerf", head-slapping, traits that tend to be found on them. I didn't tune in for long as it was late, but I did catch a bit of the livestream with McToon and some of this kind of talk and behaviour was creeping in. It would be easy to get accustomed to this kind of thing too much and that would be a terrible shame. What's always impressed me is the general lack of this on your debunks, along with really concise, clear, explanations - even mock ups with light-sources and whatever - to show where these people are being misled and not thinking rationally. These are the kinds of things that really ought to help flat Earthers question themselves (considering that they are "open minded" and "interested in the science" etc!) as to whether they are right, or whether, sadly, they have been manipulated into falling for a lie. These are the kinds of videos and approaches that I feel I could compile and share with somebody in my own life who is sadly down a very deep rabbit hole with this cult and a whole host of other conspiracy theories and religious issues - whereas I could not, ever, show them material from SciManDan, FTFE, McToon or especially "Creaky Blinder". It is one thing to challenge Flat Earthers and to robustly tackle some of their leaders who operate this cult for their own status and profit, as sometimes it just has to be done - but it is quite another thing to actually help get people OUT of flat Earth. The other channels seem to forget this, or have simply given up trying. I can understand why (as they are some of the most stubborn people you can possibly encounter and it is an absolute nightmare to reach them when they are so far gone), but cracking out video after video that are always taking the piss or chuckling with "I just can't believe they said this!" mirth is not an environment that would be appealing for anybody to change their mind on. In fact, I reckon it would only send them on the defensive and entrench their views of "defending" their side. I was impressed again with the way you dealt with Nathan Oakley. This is a valuable channel in my opinion and I'm glad you're doing what you do, in the way you tend to do it.

@mcgeorgerl there are a couple factors that might go into play on that. First, some time after Eratosthenes, a man named Posidonius used a similar method to measure between two other points from Eratosthenes, and got an inaccurate result which cut the circumference down from 24-26k miles to roughly 18k miles, the lower estimate seemed more accurate to Ptolemy, who included it in his "treatise on geography" in the 2nd century, which was used by the European explorers. The other factor being that Eratosthenes' measurement was accurate to the length of the equator, so a West-East circumference rather than the Meridian which is a North-South. I can link the article with this info if you'd like to read it for yourself.

Hard sometimes to believe that so much of this was based upon the lack of decent timepieces. So, Columbus's calculation East-to-West was off. His West-to- East was probably off as well since he was a reader of the tales of Marco Polo although I do not know if Columbus made a map of Polo's exploits as others had. I've also tried to find examples of earliest globes. Some of the early cartographers would draw 'gores' that people would acquire and then glue them onto appropriate sized wooden balls.

The merry go round analogy was a very good explanation for the lay person... it clearly shows how you would align with the rotation of a flat earth. I wonder if there's some similar simple example that would show how an equatorial mount works with a the actual Earth (something folks could intuitively 'get'). If there WAS a flat earther who actually was interested in the truth (a bit mythological... but it IS possible) then examples that are simple and intuitive might be a good way to reach them.

Advice for people who are stupid enough to believe that the Earth is flat - Find a ball, like a beach ball. Tape a small plastic person to the top of it, and tape another small plastic person to the bottom of it. Now pretend that one of those is at the north pole, and the other is at the south pole. Now rotate the ball, and see if you can tell what each of those small plastic persons would see if they look straight up. One of them will see everything above them rotating clockwise, and the other will see everything above them rotating counterclockwise. Now tape a small plastic person exactly between the other two, and rotate the ball again. The new person when he looks up will not see any rotation above him at all. That new plastic person will only see everything moving across the sky above him. He will observe no rotation, even though you know the ball is rotating, because you're the person who is making it rotate. Try putting small plastic people on the ball in various places, and rotate the ball, and figure out what they will see if they look straight up. All of this matches exactly what people on Earth see when they look up. Now try to tape small plastic people to a flat disk, and see if you can get them to look up and see the same thing that people see on the real Earth when they look up. Rotating the disk is allowed, but bending the disk is not allowed. This is the best way that I can think of for stupid people to figure out for themselves if the Earth is flat or round, rather than having to just decide who to trust.

More simply put, an equatorial mount rotates on a plane, since the earth is rotating. On a flat earth, the camera would have to spin in a cone to keep focused on a single celestial body, and the cone would have to be wider the further the celestial body you are centered on was away from Polaris. Since it doesn't rotate in a cone, it wouldn't work on a flat earth.

did you notice sun illumunates flat-earth in a circle at a time? but real data show half of the earth can see the sun at anytime. and if you try to draw this on flat-earth you need to try really hard whereas globe is perfectly illumunated at-half without any fancy drawing.

Yep. Flerfers have yet to explain how a small, nearby Sun can somehow extend its light all the way out to the edge of the world, while at the same time limiting its range to only the north pole (during the equinox anyways). Of course, they've yet to explain pretty much every one of their stupid conjectures, as far as that goes!

No, it isn't a question of trying really hard. It's a question of being impossible to show varying day length and seasons simultaneously without invoking magic or denying that what we observe in the northern hemisphere also happens in the southern hemisphere. It's all total bollocks.

@@PeerAdder it actually still possible to map the light. afterall, we can still map globe to a flat paper. the thing is, the shape is not something to draw easily, plus it needs to explain how other areas gets dark. you need some magical barrier to stop light so to create night. for globe-earth the explanation is simple: sun-facing surfaces are light, the other side is dark.

@@YilmazDurmaz no, we really *cannot* map the globe to a flat piece of paper or vice versa without introducing cuts, creases or distortions. We *can* correct for the distortions, this is how every atlas works, but the distortions are unavoidable going from a sphere to a plane. We can't just put a ruler or protractor on the resulting flat map and measure distances and angles directly. Which is precisely why no accurate, undistorted map of flat earth exists. It's the same going from a plane to a sphere. If the earth really were flat then we absolutely *could not* produce an accurate globe map, no matter how hard we tried. Try wrapping a ball in a sheet of paper, or unfolding an orange peel so that it lies flat, and you'll see exactly what the problem is. And of course the Flat Earth explanation for day/night variations amounts to "if it's sunny it's because it's sunny, and if it's dark it's because it's dark". Which is no explanation at all, like all their other so-called explanations.

i mean the STARS prove we're on a ball! they don't have a north star in the south! why would the entire perimeter of the pizza tray surrounded by the ice wall have the same stars and not have the north star! i love the collective fun we have at the expense of flat earthers

Only recently discovered the wonderful world of flat earth and the delightful Mr Oakley. I'm an astrophotographer and it made me think whether there was practical proof that I could secure with my telescope, just for fun (since its all CGI anyway according to flerfs). But then I remembered how my EQ mount functions and realised all of my deep space images prove a globe.... Res ipsa loquitur. The mount CANNOT function on a flat earth and ESPECIALLY not in the southern hemisphere if the NCP is about the geographic centre. So glad someone has actually made a good video on this as it is definitive proof.

@@melvinp1324 how is it not? It's not even "clever kit" on the tracker. It just rotates along two axes at a specific rate. How can it work on a flat plane given that the point it is rotating in line with (the NCP) would be moving laterally away from and/or towards the mount? Similarly how would that track using the same method in the southern hemisphere bearing in mind the tracker doesn't know if you're in the north or south? The actual mechanical motion of the tracker requires it to be on a rotating sphere (or mostly sphere like shape) or on a sphere which everything else in the universe rotates around for it to work irrespective of your position on the earth. Similarly, the tracker could take an image of the NCP also and only need to rotate along one axis. Which would be impossible on a flat plane with a dome/firmament above it where either the flat plane or the dome rotates due to the fact that the stars would move along two axes (as they would move closer and further away and left/right over the course of one night)
