DO NOT LOOK AT THE SUN DIRECTLY! Here's how to turn a pair of binoculars into a projector to safely observe the Sun. You'll need a tripod (or a stack of books), duct tape, a boxer cutter or scissors and two pieces of white cardboard.

Awesome tips. This one works way better than the cereal box one.

I made this rig with some dusty binoculars, cleaned as best I could. I saw some dots on the projection and thought it was more dust. I went to spaceweather to see what the sun looks like today. Those specks were SUN SPOTS! I've not done this before. Cool! There is dust trapped inside the binoculars, but the dots came into focus just as the sun's outline did, too.

Use good judgement. As long as your paper isn't a mirror, you should be OK. But if it seems way bright, use off-white paper or brown cardboard.

And/or place the paper farther away from the binoculars. That'll make the image larger, too.

If the sun on the paper looks too bright, just pop on some sunglasses. I watched the transit in 2004 like this and there was no danger of it being too bright at all, maybe because I focused it further away than in the video, roughly a meter. The sun was bigger and the light more spread out over that larger area. I also tried it through a small open window in an otherwise dark room and focused the sun nice and big even further away. Have fun!

Hey, would weak magnification in my binoculars effect this?

This video has a very interesting element. Look at 0:38, 0:45 second. One can see the Moon. But that is not all. If you see carefully then you can make out things on the Earth is illuminated exactly the way the Moon is. Note the shadow of the head of the girl (sorry I missed you name) on her shoulders. If at this point in time if some one was holding a ball then the ball too would have looked exactly like the Moon behind.

how does the moon come between earth and moon with us ever seeing the moon in front of the sun

@narcovice 6 жыл бұрын

they say the physical moon in front of the sun and earth are seen as shadow but not the moon itself

@edwardng6337 6 жыл бұрын

In the position near the time of the solar eclipse, you are looking at the dark (unlit) side of the moon. With no light shining on the backside of the moon, it is not visible to us on earth at that moment. It's akin to being in a dark room with the light turned off. The walls are not black. It's just that there's no light shining on the walls to make them visible. Another example, at night time during those times when the moon is not a full moon, you really only see the part that is lit up. The other part is not visible. Because it's night time, you might think the "dark" part of the moon is black. It's actually not black -- it's just not reflecting any light that would let you see that part of the moon. The other reason that you have no chance of seeing any hint of the moon just before the eclipse is the blue sky. In the daytime hours when solar eclipses occur, the blue sky you see is actually the sun's illumination of earth's thin layer of atmosphere. The earth's lit atmosphere further obscures any possible view of the back side of the moon.

the back of the moon is never shown from earth like the edge of the earth that apears flat

I got better option for you to look at sun with bare eye Take a piece clear flat glass burn it with matches or lighter till it gets smoky covers in smoke , take look at the sun enjoy

faarhaann khan Please be careful using the Match and Mirror technique, it is very dangerous, some people are successful, others have gone blind if you did not do it correctly by mistake. Please protect your eyes, do more research and view more videos and find the best way that you feel comfortable with. The main thing is to be safe, protect your eyes! It's not worth it if anything goes wrong. Thank you for sharing all your ideas.
