Ugh thank ❤I’ve been trying to figure this out for an hour 😂🤦🏻♀️🤦🏻♀️
Thanks man, ive been putting the barlow lense in the mirror😂
😂😂😂
Same 😂😂
All am gonna say is just thank you bro, you a real homie for this one
Thanks dawg
You can do this another way, by putting the barlow in between the eyepiece and the diagonal. This is one of the main reasons why some barlows have a belt tensioning system instead of a standard bolt tensioning system.
There is another problem though with some barlows being so long that you can't focus your telescope. This is one major disadvantage of the "Eyepiece > Diagonal > Barlow" arrangement as opposed to the "Eyepiece > Barlow > Diagonal" arrangement, but the blurring could also be because of poor seeing conditions and maximum magnification.
Barlows also work by spacing, and as such : if you move your Barlow lens further away from the eyepiece, you get more magnification, thus sometimes blurring your images.
How to calculate maximum magnification :
Telescope aperture in inches x 50
Telescope aperture in mm x 2
How to calculate seeing conditions :
3.5 arcseconds or more : Poor seeing conditions
3.4 - 2.5 arcseconds : Fair seeing conditions
2.4 - 1.7 arcseconds : Good seeing conditions
1.6 - 1 arcseconds : Great seeing conditions
1 arcseconds or less : Excellent seeing conditions
does this mean my telescope that has 70mm aperture should get a barlow below 1.40x zoom
@@bonk747klm If your high-powered eyepiece powers around 100x, then yes, but I recommend you only get a barlow for the low powered eyepiece, since 1.4x barlows don't exist, and if they do, they'll either come from some cheap chinese brand or an exotic, highly expensive one like some of the discontinued AstroPhysics products.
I have an barlow super long
Thank you so much brother!
Thank you so much I understood all of it. You earned a sub
Thanks very useful info for me ❤
Bro I was doing it wrong thanks for the tip 😂❤❤
Read above comment. Not doing it wrong if you put it before or after the diagonal piece. Just diff magnification
Placing the barlow in front of the diagonal increases the power to more than 2x. It is 2x power if you place the barlow after the diagonal with the eyepiece in the barlow.The further distance between the eyepiece and the barlow, the higher the power magnification.
my right ear enjoyed this
right ear is superior
This is important content. A related book I read was also significant. "Stars Aligned" by Olivia Whitestone
Thanks bro i was trying to figure out for 2days 😅
Keep in mind: some telescopes (like hexeum) have the Barlow lense go on after the diagonal mirror
Noted! Thanks

Is it also possible just to put down the eyepiece and put the Barlow on the mirror thingy and then reattach the eyepiece to the top of the Barlow?
Thank you very much❤
❤❤❤❤ thank-you I am facing this with my telescppe
You're welcome 😊
if I have the 36X and I put the X2 Barlow I have the 72X (sorry for the question, I've only recently got a telescope)
⚠️ Warning!⚠️ If you have a small scope a barlow will make your view through the eyepiece blurry. If you want higher magnification you need to multiply your apperature by 50 in inches, and by 2 in mm. That's the maximal magnification your telescope can handle. To get the magnification of the eyepiece divide your focal length by the eyepiece diameter and multiply the result by the Barlow magnification. If the number is lower than your telescopes max magnification you'll be fine with the barlow.
That’s why I never use my Barlow lens…thanks for the help I didn’t know why it was blurry
THANK YOU! I got a used one and have 0 clue how they work😅
You can also put it on diagonal
thank you so much
You saved me bruv
I have a tasco I'm a beginner my eyepiece is too big😮 idk. Help! Thank you
We just got our telescope and we're trying to figure it out, we were putting the Barlow lens in the mirror. That being said it's the only place that will fit so I don't know how to put it on where you just put it on
It's help to zomimg???
I've been trying to figure this out for about 2 months
😂🏴🙏🏻
Can fit in any telescope
Can I use any Barlow on my telescope?
Hello, I have a svbony sv 28 25-75x70 spotting scope telescope, is there a barlow lens for it
I just bought the same brand of telescope but why can’t i see anything? This is the 1st time im using a telescope so still learning
So helpful 🙃
Glad you think so!
Mine is the completely opposite I have to put the diagonal Lena’s first then the Barlow
Is it possinle to screw the barlow a bit more out to gain more zoom? Maybe make a 2x barlow into a 3x?
That seems like a smart idea but no it's just going to make it blurry
Help mine is just completely black when I look through it when I remove it and put just the eyepiece in I can see everything and even when I remove the eyepiece and just look through the Barlow
Did you try it in the daytime? If that's not the problem, then it's one of these 3:
1. Since it increases magnification, it makes objects dimmer (so you might not have pointed your telescope to something bright enough)
2. You may not have removed the lid (I hope not)
3. When observing at night, you moved out of the field of view when you changed eyepieces
Im having same problem
Also doing that will turn 2x into 3x Barlow “celestron”
Also you couldn’t focus it for most of celestron and other telescope
(Here some tricks : for doing that I recommend removing the diagonal and putting the eyepieces directly in the Barlow instead because the area where the light collide will go beyond the normal without Barlow lens 2.put it after the diagonal that’s a lot more simple also)
Anyone know how to make a kookpte telescope? I can’t find a video describing it
To amy beginners. I highly recommend you save your money and buy an 8 inch dobsonian. They are extremely beginner friendly and are quite simple to use once you get the hang of it
Thanks for the tips
Will it make it upside down
Not at all, that's what is so great about them !!!
Can I have link to the lens you used
The Barlow lens came with my telescope I bought from Meade:
www.meade.com/telescopes/meade-infinity-70mm-altazimuth-refractor-telescope.pdp
Even though the Barlow lens isn't sold separately, here is another model also sold by Meade (a bit more on the pricy side):
www.meade.com/meade-series-4000-1-25-2x-short-focus-barlow-lens.pdp
Hope that helps!
Thanks
Personally I don't usually bother w/ the Barlow lens. Its easier just to use a lower eyepiece.
They don’t increase the magnification of the eye pice they increase the focal length of your scope
Thanks for the info! I didn’t know that at the time of making the video…
Ironically, I just published a video about focal ratio it’s not focal length but it’s pretty close
Focal Ratio explained in 60 seconds
ua-cam.com/users/shortsD_DrSXXmyTU?feature=share
Ive been putting the barlow underneath the eyepiece 💀
That’s actually the correct way…
@@twm1452 1.5x if before diagonal, 2x after diagonal. for a 2x barlow lens.
your actually wrong bro, the barlow multiplies lenght of your microscope, basically making your microscope longer so you can magnify with more strenght without going over the limit of your scope.
Question: although this is very easy to assemble, why can I barely see anything? It is supposed to bring things closer and not farther or nothing. What Im I doing wrong? I thought to ask before calling the telescope seller, in case it's defective
R u sure the target is in focus? You may have to change the focus after you place the Barlow lens
Most likely because your telescope's mount is inaccurate and wobbly, and also the image is much darker and longer focal lengths Don t help that
Celestron az60 barlow doesn’t go like that?
Oh well I'm sorry I don't own that telescope but I'm sure that with a little more digging you'll be able to find the right tutorial
Can you give the link of the barlow lens you used in this video and is it good?
I'm using the barlow lens that came with my MEADE 50mm telescope:
www.meade.com/meade-series-4000-1-25-2x-short-focus-barlow-lens.pdp
But if you're looking for something cheaper these ones are great too:

I am using a celestron omni 2x 1.25 barlow and it is very great on 70mm celestron travel scope
It doesn’t focus😢
you probably reached your telescopes maximum magnification, once it reaches it, the views won't focus good.
Me too😂😂
i was doing it wrong 😂
Happens to the best of us
Me too
actually i think it’s wrong, well technically.. unless you need more than 2x magnification..
But why use it if it were ok in the first place ???
I can see you now …..
Which Telescope You're Using ?
Meade Infinity 50mm it's not the best but it does the job
@@marcolaurettobon Ohk Thanks
Bruh i thought it must go with the eye pieces
same
Do not use a star diagnal with barrow lens
Well most commonly it’s used between the eyepiece and the refractor but I think it can be used
100th like
Ohhhh I get it than u mister
😅
sus intro
Yeah I’m still working on all that is “special effect”…but the binocular effect is definitely sus
Fake
Dude what do you mean? It might not apply to all telescope models though
I have a Barlow lens in my telescope
You're doing it wrong
I was trying to figure this out, then UA-cam came to the rescue and recommended this video 😂🫶
