[@Sirenheade456]

can you see planets with this?

[@epicfantasy]

@415p2 I haven't tried it but the 30 cm fl lens should be good too. The 30 is the focal length.

[@epicfantasy]

@00lightbulb yes, I have the mirrors to make bigger telescopes. One mirror is 8 inches in diameter. Those will be fun projects. Going to do vids.

[@epicfantasy]

Yes, this telescope inverts the image, comes upside down. if you want a right side up image you have to use a double convex lens and a plano concave lens. Or a double concave lens. Hope that helps!

[@a.m.arteaga8369]

You are amazing, it's people like you that are blessings. I admire you so much, thank you for taking your time and making these wonderful as well as fantastic videos! God bless you!

[@epicfantasy]

possibly, but you can get bigger rolls. magnifyiing glasses come in different sizes too.

[@epicfantasy]

@madebo1294 YEs, the sliding allows you to find the focus. Only way to see clearly.

[@epicfantasy]

@ignilc This is an excellent question and difficult to answer. You probably mean Saturn's Rings? Part of it depends on how clear your night sky is and how dark. But I am not really sure. Maybe, 25ish?

[@epicfantasy]

@Dragon1813 the upside down is normal

[@koraymelihyatagan8111]

You can use a little gap that youcan create with your hand as a lense. Just tried it and it worked.

[@epicfantasy]

@lavonminor Grats on making the telescope! Yes, it is an inverted image. Used for astronomy! You can correct this by changing one of the lenses to a double concave.

[@epicfantasy]

on amazon. Might want to try american science and surplus too.

[@epicfantasy]

@Icklumpus great comment. But, isn't that the focal length? and to use the thin lens formula to get the magnification and focal length you need both radii of the lenses. difficult to figure unless given to you. Great comment though.

[@epicfantasy]

Thanks, fun little project! I bought a telescope mirror with an eight inch diameter. Going to make a very big telescope. Will be a fun series of videos.

[@nihar1409]

well the image will be inverted for closer objects but if u want to look at distance objects like moon and stars they appear the same even if inverted so it wont b an issue

[@epicfantasy]

@xXUndeadViperXx On a dark night you can see the Orion nebula without a telescope! So, any power is good, binoculars are alos good!

[@epicfantasy]

@withoutthefire Yes, I believe so. That sounds like the combination that Galileo used.

[@TheGreenOpossum]

have you ever observed some exoplanet transits maybe by doing photometry or something similar? oh i forgot to introduce myself I`m a 15 year old student from southtirol in the northern italy and i am in the astronomy team of the school and maybe we will have the opportunity to go to a congress about exoplanet transits next year but my english is not so good yet i hope that I will learn some astronomical-words until that moment. yours is my favorite youtube channel:)

[@s.sradon9782]

I suggest putting a long slot in the side of the inner tube and fitting a bolt into it through the outer tube so that it won't fall out the other side

[@epicfantasy]

@ElizabethGama31 amazon has them. Links are on my website too. You can also buy kits that have the tubes and lenses.

[@epicfantasy]

no need to fix it. It doesn't matter for stargazing. But, to get a right side up image you will need to replace one of the lenses with another type.

[@SemiDigitalTV]

Than you this help so much. Thanks for also making a clear to the point video! thumbs up

[@epicfantasy]

@Maize52 no, you wouldn't be able to get any details. Just some of the colors.

[@ParaglidingManiac]

How about a video or some pictures of how this little homebuilt telescope operates?

[@epicfantasy]

@2583654 not a whole lot but thats ok. Take the telescope out on a dark night and enjoy the night sky. Best thing with that telescope would be to take it out and look at the moon when it is only a sliver. You should be able to see some craters. Not during a full moon, just when moon is half or less. You can see mars, jupiter and saturn with just your eyes, the telescope will help some.

[@tchibisarmelia8117]

je vous remercie pour les cours sur l'electronique, car cela m'a permis de connaitre les specifités et le role de chaque composant' je vous encourage parceque dans le monde actuel on se doit de s'entraider, merci encore!

[@aztonmartine]

tHANKS MAN... IN FACT I WANT TO SEE THE MOON ,SO I WANTED TO PREPARE A TELESCOPE , I THINK U R VIDEO HELPS ME...

[@southernexposure123]

That's a gooooood explanation.

[@epicfantasy]

@sania1027 Yes, I believe it would.

[@DayTrend]

nice , i have mad an 6.5x telescope from a Plano Concave (10mm, from an old camera)& Convex Concave (65mm from a magnifier glass)

[@epicfantasy]

@anilareya amazon has them. I have links on my website.

[@da1681]

Very well explained. Thanks. Want to try it myself.

[@epicfantasy]

@TinyTinTinsTutorials 1, yes 2. it can vary a lot, 3. amazon, 4 exactly . 5. go for it and have fun.

[@epicfantasy]

The length of the tube depends on the focal length of the lenses. The telescope has to be able to slide, so you can focus it

[@epicfantasy]

@DUMBTVSHOWS This kind of lens configuration only reverses the image. so that's normal. People sometimes see it and think something is wrong. To get a right side up image you need a more complex lens setup.

[@epicfantasy]

@begginersluck Thanks for viewing. Magnifying glasses can be tricky to use. You are going to have to experiment with them and use different tube lengths. And two lenses of the same diameter will be ok. About finding the lenses for this exact project. i have links to them through amazon on my telescope nerd website.

[@JoylynAvaso-uu3rr]

😮I really appreciate your video 👊🏾

[@msgossipway2much]

This is a great video! Easy to understand and it kept me interested til the end! Thanks so much I will try it! EXCITED!

[@bugslightyear6017]

Hello sir, Your video is most helpful then any other video on you tube when it comes to home made telescopes.But i am a bit confused in choosing lenses. My questions are: 1- I have a Magnify lens size of a human palm, can i use it for my telescope? 2- Can we use both lenses of same focal length & diameter ? 3- Is Plano concave & Convex concave setup is more effective in magnification? 4- Can we use a very big magnify lens like one used by detectives in movies ? The best part of your video is when you teach us about lenses at least now i know about concave,convex,double convex & Plano convex. Thanx :)

[@cyer5]

I appreciate your effort in bringing this presentation.Nicely done.

[@jetsfan333]

can u do this with 2 of the same lens?? im trying to do this for a school project and im wondering if that would work

[@viktorgustavsson8164]

The angular magnification can be calculated by dividing the focal length of the first lens with the focal length of the second lens, thus if you have two lenses of the same kind the magnification will be x1 (no magnification). So, nope.

[@neoanimalia884]

Yes, you can but the focal length of objective lens should be greater than of eye piece.

[@epicfantasy]

@oel97 probably not.

[@captainhamdy]

thanks for your video but I want you to describe how can i measure the position of the focal point from the lens to determine the position of the pinhole or the reticle inside the rifle scope (I know that you mentioned it in the video but I didn't understand and how does the thickness of the lens affect on the magnification ? thanks

[@wayangede2007]

Hello Mr Epic Fantasy,one more my question,How to increase the power magnifier?My telescope magnifier now is about 5x,how to increase become 10 x? is the eyepiece lens have be made smaller? Thank you.

[@chintan1500]

Can you tell me exactly where did you get the telescope lenses? Website or a store where you found it

[@scasey1960]

Nicely done!

[@jdiplaris]

can you make the telescope the right side up with double convex lenses?

[@epicfantasy]

@Dragon1813 yes, thats right.

[@jairyjojo3033]

can the eyepiece lens have 0.5 focus length, if so what all can you see with a telescope with 40x magnification?can you see stars, planets, etc?

[@zozo71zozo71]

very very simple and coll staff !!

[@GeorgeChar95]

nice video! of course i don't need to make one cause i have the Skyliner 8 inch by skywatcher. But watching this video is very educational!

[@ignilc]

what is the approximate magnification needed to be able to see jupiters rings?

[@floyd8262]

Where can I get the primary and secondary mirrors for building a 8" reflector telescope?

[@sania1027]

would it work if i have a convex and a concave? both exactly the same size?

[@shyansuperville6952]

this helped a lot in my project

[@angryadrien]

Great information. Thank you

[@giovannap4926]

Thanks for this tutorial!

[@nikis11nikis]

Hello Mr epicfantasy, u have use the convex lens so it will make a inverted image, so hw 2 solve the problem of inverted image through the telescope... plzzzz tel me :-)

[@DexterColdplay1fan]

O M F G THANK YOU SO MUCH! This is everything I need for my school project!

[@jessjude2835]

epicfantasy where did you buy the lenses from?

[@xXxMCmanxXx]

pro tip, know an optician. They can hook you up with 2 dollar lenses

[@epicfantasy]

@rajneeshru inverted

[@sanan22]

where did you find the lenses? I've been looking for lenses and all I can find are very small pocket lens or large hand lenses.

[@epicfantasy]

@MySerenity11 Nice work! Great way to stick with it! Enjoy your telescope.

[@EclipseBlaze]

anways good going man...:] im damn sure that u took a lot of energy on explaining this

[@megha7564]

hi i have a school project on ths i want to know what focal lengths should be used ? i have one convex lens of f=32 cm (i checked like u taught in yr vid):) i e to buy the other what focal length lens should i buy???

[@KASHTutorials]

Great video! Quick question though, Are you able to make this if you have two of the exact same convex lenses? Or do they NEED to have different focal lengths?

[@michaeljonathan9431]

How did you managed to get the lens out of the magnifying glass holder? Pls answer me mann

[@premgurusamy8403]

What is the difference between magnifying glass , objective lens and eyepiece lens.Can You Tell Me ?

[@novelist10]

i watched this video, and twenty minutes later i had a small telescope. very cool vid.

[@stephaniepaderes3430]

thanks for the vid. it helps me to make my project telescope easy.. :)

[@wayangede2007]

Hello Mr epicfantasy,I use two lens double convex with 9 cm diameter,and the telescope made by PVC pipe about 90 cm length,is it right?

[@geoffreytyson3730]

thanks for this! where would you suggest purchasing the lens online? It'd be so cool to try it with the plano concave and convex concave lenses.

[@thorntonchavez1627]

that was so easy thanks for making this video

[@thorntonchavez1627]

+Thornton Chavez n

[@dollydongphuong]

Where do you go to buy these magnifying lenses without the handle?

[@epicfantasy]

@nayyark23 NIce work and good improvising! The upside down is normal. doesnt matter when you are looking at the stars and moon. But some good improvising on your part!

[@darkceratops-roblox6258]

Where would you get the glass that makes it zoom in.

[@epicfantasy]

@dollydongphuong lots of places. amazon, I have links on my website.

[@epicfantasy]

@snowcrystal2510 Good job on the telescope. The eyepiece lens shoudl be about 50 cm away from the objective. We make a sliding tube telescope so you can just adjust that as you need it. With a 10x telescope you should see some fun stuff like craters on the moon and a coouple of plantets like jupiter and saturn.

[@baderalikhan5650]

Can I use this for looking at the planets?

[@ccww7239]

I'd say minimum magnification to see detail on planets is about >20x. But even with around 10x you can possibly see the moons of Jupiter.

[@antolus22]

I have exactly the same scissors like yours:D BTW good tutorial

[@ayushjha5796]

it helped me a lot thanks to you

[@crazydrifter13]

Hi how is it to look from this telescope? I mean how is the clarity etc? Can you see the moon clearly? Saturn? Or ISS ?

[@AlvinDarmawan05]

Up to Saturn

[@oel97]

hi i have a tasco 7x35mm zip focus binocular and a regular lens from glasses...is there anyway i can build a telescope??please respond...thank you

[@epicfantasy]

probably, hold them up and see!

[@alexchooo123]

this goes write in my favourites :-) i have a question at the end i didnt get it when you focus the light when its clear what you do next ?

[@stevendavis3991]

Thanks for showing how to find the distances of the lens.

[@wayangede2007]

i have made one,i use one big lense on objective and one small one on eyepiece lens,why the pictures is reverse?Thank you.

[@JackWahSJ]

May I know 1. Will the magnifying power of the lenses affect the magnification (higher power bigger the magnification)? 2. And for both lenses shall i have the same magnifying power or difference (both must be 2x, 4x etc.)?

[@garniak]

1. focal length only matters 2. irrelevant

[@anukritsharma1798]

can i use plano convex lens with+12 d on objective?

[@anukritsharma1798]

pl answer........................................

[@omarehab2151]

What is the power of the two lenses

[@ElizabethGama31]

Do you know if i can use something else other than glass lenses??

[@Dragon1813]

@epicfantasy Would that change if the eye piece lens was a Concave and the other was a double Convex?

[@rajneeshru]

Will the image be inverted or straight????

[@ignilc]

@epicfantasy Jupiter also has rings, and is much closer than saturn, and much larger. And I thought it'd be awesome to see its rings, especially with a homemade toy. Anyway I watched your tutorial, and today I bought some lenses, one +1.5 dioptres, and one -5.5. will these do for a galilean telescope? very nice vid by the way!

[@UFT1]

Is a magnifying glass a double convex ??

[@JavedZBH]

I have 2 double convex lenses and im getting an image but it always seems to be upside down. How do I fix that?

[@ralphallada]

Thank you

[@michaelmafwenga1129]

I like it 😊

[@lavonminor]

I made the telescope and bought the lenses off line... My son loves it but everything is upside down. I used the same ones you had posted on your website. Is that how it is suppose to work?

[@mohanpaudel6087]

i have to download this video .
