2017 Eclipse Viewing Using Telescope Projection Method and howto - Sun Spots too!
HTML-код
- Опубликовано: 20 авг 2017
- I deployed a safe and highly productive method of viewing the 2017 Solar Eclipse in the USA. Unfortunately, because I am in Maryland, we only saw 80% coverage, and our view of the eclipse never got to totality. Still, what we did experience was awesome. If you are looking for a way to safely view an eclipse of the sun... I highly recommend this telescope projection method. You can also use this method to view sun spots even in times when there is not an eclipse.
I said the next one like this will not be for another 100 years...but I believe they are referring to a path of totality that spans across the entire US. There will be some other total eclipses....just not as wide of a path across the US!
I have exact same telescope and my Sun len is no good. Didn't think of it until on day of April 8th 2024 eclipse, I was about to use my welding shield (not helmet), I decided to check RUclips for pinhole and paper setup for my son. Came across your video and I have everything, took me 5 min to set it up and was very pleased with the setup!! It was perfect and able to use my telescope and whiteboard to observe Eclipse and took photo of phases. I use 25x len. Perfect!!! Thankyou!!!
I just used your idea for the ring of fire eclipse. It worked great. We had a viewing party and everyone loved being able to see the progress and ring. Thank you for this video!
It is unclear how you avoided the heat causing the secondary falling onto the primary. Also, some eyepieces are incapable of coping with the heat.
My telescope is an ancient Sears refractor. It came with a screen & lens & attachment method especially for solar projection. Its about the only thing we've ever used it for. They sell a newer lens to help increase resolution now. But I seldom want to mess with setting it up. So I never bothered getting it.
VERY well done! I've got an 8" dobsonian. Might be the same model! I'm going to copy your method for the 10/14/23 eclipse that runs through Portland! I'm North of Seattle, and we are expecting 80% up here! Thanks! :)
Thank you for posting this, very helpful!
did you check your eyepieces after the experience? were some of them burned?
Hey, are you gonna use this technique again in the April 8th, 2024 eclipse?
I hope you still own your set up for the solar eclipse in April. Not quite a hundred years later. Lol
Which eyepiece do you have?
could i use this without a filter without ruining eyepieces or my telescope?
You are a genius!
Great idea ❤
I , think 🤔💬 ? ; I will try the same - setup - you have on my latter.

I , am thinking 🤔💭 ? ; put my projection screen ( on the side ) of my ladder 🪜 with clothespins , instead of clamps on the ladder steps.

Thank you 💘

Does the telescope have to be pointed directly at the sun? Soeone try to answer by tomorrow, because the eclipse is tomorrow and i have no idea what im doing 😂
Hey I'm getting prepped to do a similar setup. Did you need any filters on the telescope? Also can you explain how you safely aimed the telescope initially? Just trial and error?
I know this is from 5 months ago, but thought I’d answer for folks looking for an answer in the future.
There are plans online for a diy device to help you aim it, and even some things you can 3D print. From my experience you don’t need anything other than the telescope. Since the idea is to point directly at the sun, just look at the telescope’s shadow on the ground. If you’re off center you’ll see a cylindrical shape, but when it’s pointed in the right direction you will only see a circle.
Your mileage may vary depending on your tripod and what types of attachments are on the side of your telescope, but the general idea should hold.
@@andrew.nicholson Thanks for the follow up! I ended up using the shadow and got some great projections of the annular eclipse!
Bro I also used this trick but the result was "my burnt lens"😭😭😭
I’ve always heard this is like a once in a century phenomenon but here we are six years later, and the exact thing is happening again in a very similar location?
It's not the event itself that's rare it's about where the event is taking place. But like yeah you have a point, people tend to over exaggerate things like this.
Is there any fire risk by doing this method? I’ll be using binoculars but just wondering how long can this be done safely?
The risk area is a zone about 4 inches from the eye piece. If you pass anything through this focal point, it will ignite. It will not harm the telescope or binoculars. Just keep your screen and your hands at least 12" away from the eye piece. If you're using binoculars there are two hot zones to avoid. DG
Put a piece of cardboard over the open end of the telescope and cut a hole, off center, 3" in diameter to reduce the heat inside the scope. DG
Practicing for April 8, 2024. 😁
I pointed my telescope at the sun and a put a peace of paper next to the eye piece and the paper shows a big yellow circle but I can’t see the sunspots
sunspots arent always there, ik this is late but
Great method!
2 questions for you in preparation for an eclipse due in a couple of years:
1. What eyepiece did you use? Was it burned or damaged by the sun heat?
2. Where the focuser mechanisms or secondary mirror mount damaged bu the sun light heat?
I don't mean to be pesimistic, but this is a fantastic way to ruin your equipment, when the sun is not perfectly aligned (and that's every couple of seconds with a dobsonian mount) then it is focusing on the edge of your eyepieces causing them to burn or even obscure the crystals. if you want to try this technique I recommend doing it with a cheap pair of binoculars. don't burn your eyepieces or your telescope.
The focal point is about 4 inches out beyond the eye piece. There is no danger to your equipment. The danger is putting anything through the area 3 to 6 inches from your eye piece. DG@@capitancodigo2165

This doesn't damage the telescope at all?
It didn't damage mine at all
We have another coming in 2024 April 8th
and after 2024, next one is 2044
Once every hundred years a solar eclipse traverses America. So 2017 plus 100 equals 2024? strange math.
For real... 😂
There's a schedule that says every eclipse that'll occur in the next 40 years. You could just check it!
It normally is, america has just been very very very lucky, in the UK the last one was in 2000, the next one will be in 2090
I ruined an expensive eyepiece doing this, glass chipped right in the middle. It was a Televue 35mm Pano. Bummer.
I saw the eclipse from the top of a tower I was working on today, in Texas.. It was literally not anything special. Was a little darker than normal but I didn't really notice anything
PkwyDrive13 was it a partial eclipse or full?
PkwyDrive13 2024... Should be a better opportunity for you...
OP was spot on. 6 years later and Texas is right in line! Nice.
Great setup you really should have done the road trip to see totality, I regret not making the trip to Cornwall back in 99 :(
Once in a life time opportunity missed :(
Adrian Chapmanlaw u sound old as fuck . Old fart
I made that trip and spent the night before on a cloud free cliff top watching saturn rise, awoke at 8am to cloud from horizon to horizon :(
we watched the build up on a black and white 12v portable telly with a crowd of about 60 fellow campers.
Totality was still impressive but we didn't get a single view of the sun.
Not sure how this worked for such a long time. I tried this and my eye piece was burnt out within 3 seconds.
Refractory or reflective type telescope?
there is a large hazzard zone, between the projector (telescope lens) and the screen
this 'rear projection' method, solves that problem

Hmmm. What you neglected to explain is DO YOU HAVE AN EYEPIECE IN THE SCOPE?????????????
He did
No, he didn't. Do you even know what an eye piece is???? Right, I didn't think so.
No, he didn't@@chibbert1246
@@jakebob6332good for you Jakebob. You finally got enough guts to smart off to someone on the internet. Maybe in a few more years you might be able to do it on the phone and then years later, in person. You’re off to a great start, tough guy.
@@jakebob6332 wtf yes he did lol
You said this will only happen once every 100 years. There will be another trans-american (Pacific to Atlantic) one in 2045.
...and tomorrow.
Hope your telescope can penetrate the clouds to see the darkness
Great! But that music... Cringy
Which planet cover the sun
Moon
Moon is not a planet
Moon is not a planet.
@@viejaspeliculasfilipinas3621 ók thanks 😊
DUH!!!!!!!??
Question yourself how come, the moon never comes and view before and after the so-called eclipse like what’s really blocking the sun no one never ask a question like this
You can see only the part of the moon that is illuminated by the sun. Imagine holding a tennis ball at arm's length and have someone shine a flashlight at the ball. Have the person with the flashlight move around you, while shining the flashlight at the ball. Depending on the direction from which the flashlight illuminates the ball, you may be able to see half the ball be illuminated, a quarter of the ball illuminated, none of the ball illuminated, etc. For example, if you are essentially between the flashlight holder and the ball, you can see half the ball illuminated. This is similar to a full moon. But, if you, the ball, and the flashlight form a right angle, in other words, the ball is illuminated from the side, you see only half a face of the ball light up. This is similar to a quarter moon. If the flashlight is exactly on the opposite side of the ball from you, you don't see any of the ball lit up. This is similar to a new moon. When the new moon exactly lines up with the sun, we get an eclipse.
