Instead of using 25mm can I use 2mm eyepiece

Hey bro can you make on personal order ?
I made it 7 years back with 700mm focal length doublet lens with 4mm eye piece. I was able to see saturn with its rings.
Hello bro I think his telescope gives a little chromatic abbreviations how can I avoid it ?
@@mohammadfouzanabdullah7769it can be removed after clicking pictures using Adobe Lightroom
Wow, that's crazy!
Bro tripod is compulsory for telescope
@@mohammadfouzanabdullah7769 you cant avoid it but you can reduce it
Just come across this video. In its simplest form a telescope is a lens, an eyepiece a method to keep them aligned, abitity to focus and a method to point it where you want. You've proved that you dont need anything fancy to produce good results. About 40 years ago I made a 6" reflector using more or less the same materials so I can appreciate your effort.
Thank you for the comment 😊😊
@@VinKrishSolutions bro there is a measurement error
for that reducer 25mm in very very large and the measurement is odd one out
please tell original measurement to proceed my project.

Wow great job...🔭🔭
Thank you😊
Big fan suppose earth bhai❤❤
Thanks for actually showing what the scope can do, great shot of jupiter with 4 moons in line 👌
😊👍... could you see Jupiter?
That was a really good result for a diy telescope, really cool
This was so good but is it useful for space? This same resolution is on my phone too
Thank you 😊.
Seeing with naked eye is always better than with phone. For watching space, this may not be useful.
Heyy

Plz check
@@OmkarMendgudle Photos are really nice and clear...👍. Good work😊
Hello! Excellent tutorial, this was really helpful. I have a question, I wasn't able to find the exact reducer so I bought one which has a slightly bigger hole than the 25mm pipe. I added another 25mm joint to other side (like the one used for eyepiece) so the eyepiece segment could fit in the bigger reducer hole, so is it okay that way? Also, my lens came scratched 😢. The scratch is not on the outside but in between the two lenses. Will the scratch affect the image? I haven't used it yet because the Tripod is still on the way.
Hi... thank you for the comment...
Adding additional reducer is ok.
Even without the tripod, you can try seeing the moon. I hope the scratch doesn't affect the image quality👍
Amazing! But how will u clean the lens ?
Since masking tape is used here, we can easily disassemble the telescope and clean the lens if required.
Can i use lens from an magnifier and is it important to use eyepiece ¿
Two lenses are required. Eyepiece is very important. Not sure if a magnifier lens will work properly instead of using an objective lens.
Thanks👍🏻
😮 are baap re me ne bhi ise banaya ye itna achha he ki is se Mayne poore solar system ke har ek planet our dwarf planet dhek saka tank you kyu ki me ek

Bina paiso se thank you so much
Nice
Thank you 😊
Great video and really excellent diy telescope for this price range but can we do anything to avoid those chromatic abberations?
Hi... I have used achromatic objective lens which reduces chromatic aberration.
Hi, this is great project to make with older kids. Thanks for sharing the video. I would like to know the link tripod that you have used in the video. Pls share the link where you purchased it from. It will be very helpful. Thank you.
Thank you for the comment. I had bought the tripod from a local store for around Rs.800/-. So I don't have a purchase link for it. You may search the online stores for any similar configuration tripod.
Excellent work..,
Thank you😊
You got my sub!
Gotta make telescope today for Blood moon event (May 26 2021)
you good
What a beautiful neat nd clean work. Awesome...😊
Thank you😊
Really very nice and thanks for details
Bro I have question that eye pice is convex or concave?
And we use only convex mirror in both sides?
Eye piece is convex. Mirrors are not used, all are lenses.
Hii Bro
Plz tell me price of your tripod used for your telescope and it's legs is of metal or plastic?
And thanks for this video 🙏❤️
Price was around Rs.800/-. Leg is metal..
Can we fit the eyepiece at same range for 8mm to see planets, and is the planets are clear to aee
For the same telescope, we can use 8mm eyepiece to see planets. Total length has to be slightly adjusted using the provision already given.
wow, perfect way of explanation.....now am gonna make a telescope with the help of this video instead of buying a telescope of 10k price, i will just make it....thnks a lot
If i change my lens and eyepiece size, what will be changed? Is it only the joint of those??
The total length of telescope (lens to lens distance) should be the sum of the focal lengths of the 2 lenses.
Pls tell the size of pvc pipe and connector
@@ManyaSrivastava-j2r All details are given in video description and also in video at 01:13
Please mention if i order from the link you given in description will i get same lense and eyepiece which is actually good can you confirm and also in Amazon the images shown are little different of especially eyepiece...
@@endlessentertainment6867 Yes, you will get the same lens used in the video..
Useful and explained well
Hi I have a problem after essemblimg where it is blurry when I look through the eyepiece what may be the problem
Please see that both the lenses are in a straight line.... also try focusing on distant bright objects rather than nearby objects...
Thanks very easy I want one now
How to illuminate this telescope during night to view moon, planets like saturn etc. I am using 10mm eyepiece. Please reply.
There is no need to illuminate the telescope to view the moon, etc
Pwoliii ❤️❤️❤️
Was PVC pipe used to make all parts of the telescope?
Yes..
@@VinKrishSolutions
Thank you
WoooW!! Bravo👍👍
Can we capture bird's photo graphy with this handmade lens please reply
For bird photography, a camera with optical zoom will be better...
If i use 62mm lens means can i able to see other planet rather than moon ?
Is it 62mm eyepiece?
Well done bro👏, keep it up 👍🏻❤️
We need to make a telescope for a project. The lenses we are going to use are:
Objective lens:
- Plano-convex lens (50dia with 300 focal length)
Eyepiece
- 31.77mm with 25mm focal length
Is this gonna work?
Thank u so much!
Yes.. it should work👍. Magnification will be less.
wow!😲🤯
Sir can I add two lenses of 50mm of that lens pleas reply sir
Have not tried like that.... Not sure if it will work
@@VinKrishSolutions but please sir let me know please sir it's an humble request
@@dharmavatidevi1816 I have already replied to your other comment... pls see that
Higher the focal length of objective lens, higher will be the magnification....
So adding one more objective lens may reduce the net focal length.... Hence can reduce the magnification....
Good video
Bro 50mm double acromate lens aur 25 mm eyepiece se plant aut moon dikhwga kya please reply 😢
You can see moon clearly with this combination.... For planets, you may need an eyepiece of lower focal length...

@@mohammadaffan8139 both lenses should be in the same straight line. Distance between the lenses should be 725 mm (700+25)
We need to make a telescope for a project. The lenses we are going to use are:
Objective lens:
Calibre lens (60dia with 500 focal length)
Eyepiece
- 31.77mm with 25mm focal length
Is this gonna work?
Thank u so much!
Yes... it should work with a magnification of 20x.
Is Calibre a convex lens? I have not heard of it.
Brilliant making 👍
kya isme chromatic abrasion aa rhi hai?
No... i got a good view without aberration
Superb
Bro my refuser does not slide inside the 50mm pipe just the 40mm pipe slides which is attached to the reducer should I cut the 50mm pipe a little more ?
If cutting solves the problem, then you can trim the 50mm pipe. But if you can get a reducer which enters the 50mm pipe, it would be better.
Wow sooper 👏🏾👏🏾👏🏾
Thank you😊
Please tell your tripod model and price details
Hi... I bought it for around Rs.800 from a local market.
@VinKrishSolutions, permission to use the video for school project about DIY Telescope
You may play this video in youtube as many times as needed for school project...
Which pipe is adjusted for focus 40 mm or 25 mm .
40mm and 25mm pipes are part of segment-2.
You can see at 01:14.
Segment-2 together slides with respect to segment-1 for focusing of objects at different distances... for sliding you may loosen the screw provided. See 03:40.
Hey can you share the link for the tripod that u used?
Sorry... I bought it from a local store... But, there are many options available online...
For segment 2 can we connect the 40mm X 220mm pipe directly with the reducer..?
Hi... I gave one joint to get more sliding space near the end of segment 1. The 40mm joint and reducer together will give more of a space for adjustment and tightening with the screw.
which tripod is this ?
This is mobile tripod bought from a local store..
Chromatic aberration is visible. I think this is because of ramsden eyepiece. Have you tried kellner eyepiece.
No
What was the focal length of the 50mm lens I have read that it's not 700 mm it's approx 600mm
@@mozillafirefox5441 It is 700mm
Hey bro, please solve my doubt again.
Can we zoom in by sliding the eyepiece pipe ?
I mean if I'm looking the moon I'm able to zoom into the moon by sliding the pipe ?
We can only focus by sliding, zoom in is not possible.
Hi, can i use the refractor objetive on a tube but usin on the bottom instead the normal focuser, use a mirror like the reflectors use for redirect the loght to the side focuser?. Idk if you understqnd what im triyng to tell but im planning to mix both styles of telescopes
I am sorry, I didn't understand what you meant. But, all the best for your try.
agar eye piece 17mm ho to chelega bhai complete ???
Yes... 17mm is better than 25mm (used in this video)... with 17mm magnification will be 41X
thanks
i am happy
and successful to make a telescope 🤗👍🎉
thank you very much
@@ketulpanchal12 you are most welcome😊 and thank u for watching my video😁
Sir mera focal length 700mm hai or eyepiece 8 mm hai.
To Mai apke jaisa same PVC pipes lu to chalegana?
Ya 25mm diameter wala pipe 160mm ki jaga 140mm Lena thik hoga
Same pipes chalega👍
How to get the pipes . Is there any online website??
I have bought the pipes from a local hardware shop.
Haven't tried online...
Bro can you please help me i just did what you did in this video. But after finishing i cant see anything only blurry image is visible and bro i bought the lens and eyepiece from Anand traders from amazon the eyepiece is 8mm and achromat doublet 50mm objective is their any problem with this product or in ny work. Pls help bro 🙏🙏🙏😭
The axes of both the lenses should be in a same straight line. Distance between the lenses should be around 708mm (if your eyepiece is 8mm). If these conditions are met, the telescope should work.
Have you tried with 25mm eyepiece?
@@VinKrishSolutions no bro 8mm only
@@VinKrishSolutions bro finally after so many adjustments I made it 😭🙏 now I can see 🫂🌕
And bro can you please make a video on the diagonal mirror for the telescope 🔭 cause everything is different when I see
Can I use big pipe
The sizes used in this video are optimised. If you use higher size pipes, it may be difficult to properly mount the lenses.
What if 6mm eyepiece and 80mm lens??? Cuz eyepiece is not cheap but lens can use magnifier which is cheap
I am not sure...
4 Inch convex lens ke sath 15x eyepiece lga sakte hain...
4 inch dia or focal length?
15x or 15mm?
Bhai pipe pe black colour karna jaruri hai kya,,, aaur 50cm ka pipe chalega ???
Black paint is not necessary.... All dimensions are given in video description...
What is OD 1:14
Outer diameter
What should be the exact length adjustment to view crystal clear moon view in same configuration telescope u made ?
Total length should be 725mm (lens to lens distance) with 700mm objective and 25mm eyepiece.
Bro plz tell me can i see deep sky and planets in this
Hi... for seeing planets, eyepiece with lower focal length eg. 8mm will be required.
Hey I want to ask that are both lens convex ?
Can I use 10 cm and another of higher focal length?
Both can be convex. Here I have used a combination of concave and convex lenses (achromatic lens) for objective for better image. You can see in the video.
You can also use 10mm eyepiece and a higher focal length lens as objective.
sir thanku so much i do this becu. my scince projiect thank u so much sir ......
Sir I am makin a telescpoe with 4mm eyepiece and 62mm of lens with focal length of lens of 900mm so the measures are correct or not
You may need a telescope of more length as the total length of telescope (lens to lens length) needed for your combination of lenses is around 904mm....
i have 62mm achromat doublet lens 900mm focal length and 25mm eyepiece its good for making telescope
Yes👍👍
@@VinKrishSolutions its giving chromatic abrasion how to fix ?
hi bro. I made this telescope but all things show in upsidedown😢.You have an any solution bro.kindly reply bro
This telescope gives only an inverted image.
Okay bro@@VinKrishSolutions
sir thank you for your video but please help, since I cannot buy the eyepiece and lens set from the link above due to the country I'm from, would d52f600 doublet lens and 20mm eyepiece still work? would i also have to change the length and diameter of the pvc pipes in order for it to work? could I please have the formula to calculating the length and diameter of the pipes that I need to use referring to a different focal of the doublet lens and eyepiece? thank you so much🙏🏻
for segment 1 I also found a dia 54mm joint and outer dia 54mm pipe since I cannot find any other pipe that fits the d52f600 lens
Hi... Your lens combination also should work as a telescope. Total length of telescope (objective lens to eyepiece lens distance) will reduce by ~100mm. Total length needed will be 600+20 = 620mm approx. Since dia of your objective lens is 52mm, a higher size pipe and joint as you have mentioned (54mm) may be good. Few trials may be required to have a good fit.
As a trial, you may try assembling with the same lengths of pipes. As total length needed is lesser, segment 2 may go further into the segment 1 to achieve the required length and for focusing properly.
But for final setting, if you feel that segment 2 is going too much into segment 1, you may reduce the length of 25mm pipe (of seg 2) by ~100mm.
Finally its your freedom, anyway total length of telescope should be adjusted to ~620mm for your set of lenses.
Hope this is helpful...
@@VinKrishSolutions hello thank you for the reply sir, to be sure I'd like to ask for your suggestion before trying it out
I have calculated the ratio of the 500mm pipe in segment 1 and the 220mm pipe in segment 2, which is 11:25, therefore I am thinking of changing the pipe in segment 1 to 520mm and the pipe in segment 2 (the originally 220mm one) to 228mm which is approximately the same ratio as your original telescope, while for the 25mm od pipe to 100mm instead of 160mm to fit the total distance of 620mm (520+100)
would the above length of pipes work? sorry for the trouble caused, I have zero knowledge on telescopes, thank you so much again sir
@@AC-ft2dw Hi... since total length needed has become lesser (only 620mm instead of 725mm) increasing the lengths may not help... Decreasing lengths only may help...
Your calculation of 520 + 100 may not be fully practical.... Portion of 40mm reducer for screwing and adjustment, 25mm joint etc will add to the lengths.... so pls do not increase any lengths....
how many objective should I buy?
Just one
Bhai mane eyepiece clean krne k liye khola tha lekin ab samajh nahi aarha h ki usko dobara set kaise kru please batao ki eyepiece ke chote or bade lens ki direction kaise honi chahiye

Somehow Can I attach my DSLR to it I can't figure out?
You can place a DSLR near to the eyepiece using another tripod or stand if you want....

Thank you😊
But why the video had a cut section..?? At the last while seeing into the telescope...?? IS IT FAKE??
@@arshinavalur8753 It is real. In video recording, moon was not clear. It is photo. Upto seeing into the telescope, it is video and then I have shown the photo I have taken through the telescope.
Can anyone teach me how to scale down this telescope if I want to clearly see colors at 25 meters?🙏🏻
Will a single lens works in place of achromatic lens
Yes, but chromatic aberration will be there.
Bro, I am getting
1. 50mm f 700mm and 16mm lens @999 giving 44x magnification
2. 50 mm f 700mm and 25mm lens
@902 giving 28x magnification.
which one shoul I buy.Price is not an issue because of minor difference between the two.
I think both are good deals... you can buy any of the two... If price is not an issue, you may go for the 1st option.
Screw to which segment and how to put it into the pipe ?
Screw should be in Segment-1. You may use hot scissors or knife to easily put a small hole. Then enlarge the hole using the screw. The screw itself will form the thread.
@vinkrishsolution can u plz tell me the measurements of the segments u used ??
All sizes are given in the video description...
Sir I am making telescope 70x zoom with 10mm eyepiece not showing clear image pls help
Hi... for clear image, axes of both lenses should be in a straight line (should not be inclined) and distance between them is important. Try adjusting the distance between them slowly for proper focussing of the object (eg. Moon).

You may ask your doubts in the comments section... I will try to clarify as far as i know...
@@VinKrishSolutions for 50mm dia &500mm FL, what will be the specification of the pipes?
@@nithyajai7560 you can make the telescope with segment-1 with 200mm lesser length... 40 dia pipe also can be around 100mm lesser in length.... others remain the same...
Anyway few trials may be required to arrive at a perfect length....
I took all the dimension as given.. But the 40 mm joint is not going inside 50mm pvc pipe:( what to do?
Generally 40mm joint will go inside 50mm pipe... You may have got a thicker joint from shop...
Either you may have to get a thinner 40mm joint or adjust without using joint (wind more masking tape for a good fit)
If 40mm 'reducer' is not going inside the 50mm pipe, adjust length of segment 2 slightly so that reducer need not go inside the 50mm pipe..... trial and error method
