[@SkarestOnGaming]

When the eclipse happened over the US a few years ago, my wife and I decided to drive up from Atlanta to get to the full eclipse. It was kind of a last minute decision, and we did not have any solar filter glasses, and could not find them for anything that was not an insane price to save our lives. But we went anyways. We ended up in the parking lot of a grocery store and this couple near us saw we did not have glasses and gave us their extra pair. It was a small thing, but it made all the difference in the world to my wife and I. If you ever get the chance to do a kind thing, no matter how small, do it. I will never forget being their for that eclipse with my wife, and those folks made it even better.

[@theblackwidower]

During that same eclipse, I was also without glasses. However the local science centre was giving them away, which is nice, but they ran out by the time I got there, which was not nice. But maybe someone would give me their extra pair? No. In fact I saw someone gave his extra pair to his dog.

[@nymalous3428]

Nifty. I play paper and pencil role playing games (such as Dungeons and Dragons). In one of those games, I had created a world with a number of moons orbiting the world on which the game took place. I actually wrote up an Excel spreadsheet detailing their various orbits, conjunctions, eclipses, and so on (the world had rather crazy tides). I bring this up because some of the combinations would only occur once in hundreds of years, and there were a few that only came up one time in a 50'000 year cycle (which was the entirety of that world's history). This video reminded me of that spreadsheet.

Brilliant video! Just for fun: if you have one of those cheap & common 6"/15cm globes - a standard table tennis ball is very close to being a scale model for the moon. Give your friends or kids the globe and ball and ask them how far apart they would be to scale. Most people in my experience estimate a couple of feet or 50-70 cm. It should be about 4.5 meters (this from memory - somebody can correct me). Don't know why but this surprises people and me! There aren't many astronomical distances that can be shown to scale in this way.

"moon covering the sun" is also visible @0:00 to @0:15 as well, and @0:45 onwards, through that greenish reflection exactly in lower middle region of the video - probably due to internal reflections within the lenses of the camera, mitigating the incident light intensity - thereby resulting in clear capture of 'moon covering the sun"

[@pyxyne]

That was some cool editing! For those wondering where the real sun disc went after it was replaced by the fake CGI one, if you look very closely at the ground right below the sun at 2:16, you can see the real sun disc appearing out of thin air at an angle (you can mostly see the handle).

1:35 "Unfortunately, it's not that simple." The 2+1/5 estimate isn't actually terrible! They usually happen every 5 or 6, but sometimes there's only 1! If you have the saros (convergent 7 if [2] is convergent 0), inex (358 synodic months, corresponding here to [2; 5, 1, 6, 1, 1, 1, 2]), and a base eclipse where you know both involved cycle numbers) you can uniquely index every eclipse!

At 3:05 you could define the Synodic month as the exact time it takes to go from a full moon to the next full moon, or new moon to the next new moon. Even a second after that the moon ceases to be full or new, for the sake of precision.

I never realized how much of the sun in the sky is simply "glare", as you can see in your video the sun seemingly "shrinking" until it's suddenly hidden behind a small black circle. It's of course not shrinking but the amount of light that makes up what normally comes off as this big circle in the sky is so much less, we get a smaller circle. COOL
