There is a solar eclipse coming soon!!! How can we safely watch it? Did you know that all you need in order to safely view the sun is a piece of paper? Or that you can project an image of the sun using a cheap telescope? In this video we look at some different methods for SAFELY viewing a solar eclipse, or looking for sunspots. We discuss the difference between using a pinhole and lenses for viewing the sun, and see how easy it is to safely view a large image of the sun.

Disclaimer: It is never safe to look directly at the sun. Whenever attempting to view the sun exercise extreme caution, and be careful to protect your eyes. Do not point expensive telescopes directly at the sun! Solar projection works best with cheap refractor telescopes.

Good job Aaron! This is really interesting and useful info.

@DARRBEV Год назад

Some really great tips here, particularly like the telescope projection idea

Excellent video. I subscribed. We're going to be near the band of totality in Boise. I'm going to try the telescope in my back yard.

Thanks! Please share some pictures! twitter.com/aaron_stafford

Yes with projection method u can see sun spots 😊with out looking at sun😊

@seaturtle841 4 месяца назад

U must focus the outer edge of circle to see spots u can do it with mounted binoculars 😮❤too

@sunjasonjb2773 7 лет назад

What's the magnification of the eyepiece you're using for the telescope? I'm using a Tasco telescope but I can't seem to get a good image of the sun. It's not clear enough to see sunspots.

@morethanthesum6318 7 лет назад

I think mine is a 100x magnification. You can check where the sunspots are here: sohowww.nascom.nasa.gov/sunspots/ If you haven't adjusted the focus, that could prevent you from seeing them too.

@sanjaytamil1376 6 лет назад

i have a question. doesn't the pinhole only focus a small portion of the sun? or does it focus the enter circumference of the sun into the pinhole?

@morethanthesum6318 6 лет назад

The entire circumference of the sun, however it is blocking a lot of light, so it is not the entire brightness of the sun. The light from the sun is scattered - it is traveling in a variety of directions. With a pinhole you block out the scattered light, and only allow the beams of light that converge at that single point. This means light originating from all parts of the sun can get through, but only if it passes through that small opening.

Thanks! I have a big project and my group is very confused about this.

@rithishk4117 3 года назад

Can we view a solar eclipse by this method and Can we see exactly like this by Celestron Powerseeker 70AZ Telescope by using a 20mm or 10mm lens ??

@morethanthesum6318 3 года назад

I can’t speak to the telescope you have except to say that you should only use it if you are ok with the possibility that it may be damaged by pointing it at the sun without a solar filter. You could try switching the lenses to see which one you prefer.

@dr.abhishekjohri 4 года назад

Which eyepiece you are using?

@morethanthesum6318 4 года назад

I think I was using the higher magnification one. The challenge is the higher the magnification, the harder to keep it in the field of view. I think it works with both too.

@@morethanthesum6318 thanks.

@eman21_gg76 4 года назад

Do sunspots appear all the time?

@morethanthesum6318 4 года назад

I think there are usually some present, but the size and amount can fluctuate. The sun also rotates, so potentially there are none that are big enough to see at a particular moment. If you want to verify what you are seeing, if you do a web search for nasa and current picture of the sun, they will have a picture that shows the current surface of the sun.

@seaturtle841 4 месяца назад

Right now there spots are at a high everr 10yrs....😮

@seaturtle841 4 месяца назад

Get a cheap telescope so u don't have to worry about eye piece shattering..😮been doing it 50yrs...😊

@ashutoshsatpathy8368 3 года назад

Bro I have tried the telescope hack but the lens of my telescope got burnt and destroyed this costs upto 5000₹😱

@morethanthesum6318 3 года назад

Should not have attempted this with anything you weren’t willing to part with. Telescopes are not made to point directly at sun without solar filter. They can survive, and do, but can also get destroyed.
