- Once again Svbony as part of their promo month have sent me another one of there products to have a look and this time it's there 2X barlow lens and in my opinion the best value for money barlows out there. Unlike most this one got a few tricks up its sleeve which makes it incredibly versatile.

Svbony 2X barlow: www.amazon.co.uk/gp/aw/d/B082...
A year ago I bought a similar Svbony barlow, but with compression ring and different lense coating for the same price. Having numerous not very expensive eyepieces, I've found that sometimes I prefer to use this barlow, rather than to switch to higher magnification eyepiece.
Another use of this barlow is a simple extension tube (with removed lense tip), when there's not enough focuser length to reach focus, for example if to use a refractor or an RC scope without a diagonal.
It looks very similar to my Skywatcher one. Before people say that the one included with Skywatcher telescopes do not have the thread and the lens cannot be taken out, I know but I took a chance on one that I was able to get for a tenner.
There is another trick you can do if you take it apart - that is to put a filter in place of the glass so that you do not have to swap the filter if you are switching eyepieces.
I have been on a bit of a bing of your videos today and I have to say you are extremely helpful, thank you very much. you've made it so much easier to navigate the minefield that is Eyepieces and Barlows.
Very nice explanation of Barlow function 👍🏼. Appreciate your honest review.
i just got mine today and i cant wait to use it as part of my photo set up for tonight's full moon. unfortunately i dnt see a filter thread on the bottom without taking the lens piece off. but other than that for £19.99 its great.
Another great video Jason! I have that same Barlow, mine is Saxon. It is a great Barlow for sure, I love mine. Keep up the good work 👍👌
I basically have the same model (it came in a set of four - 3 eyepieces and a Barlow) and I can guarantee that it is very useful. I have filmed several astronomy videos using it.
I get disappointment everytim using a barlow, the view gets blurry and details on planets for instance decrease. I just used it once and was able to enjoy the view in two years of hobby, during Mars opposition a few months ago. Great video as always Jason!
You might be going past the useful magnification of your telescope using the Barlow and whatever eyepiece you have in.
After trawling Amazon for a new Barlow and being undecided, I stumbled across your video and have just ordered this Svbony Barlow. I'm pleased to report it's only £19.99 today (7/11/23). Absolute bargain. Thanks for the review.
I did the same thing 😅 This should make it a lot of fun with my son. We spent a whole lot longer staring at stars that we couldn't really see with his dad's telescope that I had no idea how to work. So I bought one that is mom proof!
i have heard you mention adding just the barlow optic on the bottom of an eyepiece once before. I tried it last night with great results. it adds some power without the extra dimming i get with the 2x barlow.
thanks, that is a great tool to add.
Isn’t it supposed to reduce the power using it that way?
I have the skywatcher 2x Barlow. It has same features as sv bony and it was first thing recommended by local astro shop and I love it :)
Great info, thanks.
Hi Jason great review..... my canon dslr with t ring and adapter could not be focused when used with my sky watcher 130..... adding this Barlow lens element now allows focusing.... keep up the good work
Thank you for this video. I'm a novice who bought a Zhumell for his son, and bought this as an upgrade. But with no instructions I didn't realize this paired with the eyepiece lol. Sigh.
I ordered one thank you…
😎👍hello from France.....
I have a Svbony 2" 2x ED Barlow lens and it also has excellent optical construction. It was the only 2" Barlow from the brand and I believe is now discontinued...
Hi Jason! I’m new to the channel, and the hobby of Astronomy. I’ve got a portable Z100 telescope, and I would like to know what you recommend I point the telescope at first (besides the moon of course)
Great vid mate.
I have been looking into buy a 2x Barlow because I have only 1 good eyepiece which is a SVBONY SV113 1.25inch 16mm Telescope Eyepiece 65 degree Wide Angle FMC/HD from eBay.
I will be buying 1 of that Barlow lens because I also have a T adaptor for my Canon DSLR camera.

Hi I want to ask what is the best 2x Barlow for astromaster 70
Hello, with this barlow would you recommend the red or gold svbony eyepiece set?
Comment for algorithm. Keep making great vids.
Thank you friend
Interesting, I got an SVBony SV137 2X barlow through their store and it has the same kind of removable lens assembly. Except the main body is a silver finish, not black, and also there's no external M42 thread on the top. It performed great when I used it a few months ago. Their products are great value, bless 'em.....but SVBony really need to put more effort into differentiating their products. Comparing a 2X barlow and a 2X barlow without clearly stated functional differences is just downright confusing for the consumer.
I was thinking of buying concenter collimator. what do you think about them?
Can I get that approx. 1.5x directly to the DSLR instead of to the eyepiece?
Not sure if you've done any reviews on Angeleyes eyepieces or not. In my Mak127 they kinda suck, maybe beter in other scopes. However, figured out something interesting about them : their 6mm eyepiece (likely all of their high power eyepieces) is actually a lower power eyepiece (I think 18mm) with increased magnitude because the bottom piece (that can be screwed off) is actually a barlow (my estimate 3x barlow)! Without the barlow part it actually performs better (less astigmatism) but at a lower magnitude (and still not great) . Just thought that may interest you and others. Sid note: can't use these with a barlow as they already have a barlow build in!
What is the difference between a Barlow and a "powermate" / focal extender? Are they just different names for the same thing or is there a real difference?
1:49 are you sure you placed it in the correct order or have I been doing it wrong all along? I usually order it: telescope, Barlow, prism, eyepiece.
Hey, I got a Celestron 60 powerseeker as a first telescope and for the last 2 months I’ve seen most of our solar system friends. I’ve been thinking in a upgrade for my eyepiece. I heard very great things about the X-Cel-Lx series of eyepieces from celestron. I want better planetary viewing that also offers a good field of view for stat clusters. Any opinion?
They are good eyepieces but they are somewhat expensive in my opinion... Precisely Svbony has eyepieces that will offer you similar views and at a lower cost... Two of the SWA series that I have not tested, 2.5mm and 4mm, with TMB design, which It is always a guarantee, and one of the 6mm UWA (68º AFOV) series that I have tested and it seems to me to be a good eyepiece. I also own a 3-8mm planetary zoom eyepiece (56º AFOV), also from Svbony, which gives excellent views at all focal lengths, and is also parfocal, although here the investment is a bit higher.
remember the celestron barlow you thought was fake 😎 food for thought hey 😂👍
will this barlow lens work with Celestron 21061 AstroMaster 70AZ Refraktor ?
Great video again!👍🏻BUT...the first amazon link goes to the wrong product..
Hello there thank you for pointing that out my friend ill correct it ASAP.
Hi where to buy
8.07 is it just me or did Jason say svboner? 😂
Silly question… is a Barlow, the same as a focal extender?
yes
Is it better than the celestron omni?I have the svbony 3xbarlow!
Hello Stephen, it's debatable really and the difference is negligible but if you twisted my arm I would choose the svbony because of the additional T-thread.
@@smalloptics753 ok thanks boss✌️
Wellll. I bought the Celestron Omini 2x Barlow . It works... but inserting it Reduces image quality noticably..
Not a huge amount but there IS a noticeable/unmistakable reduction in Clarity.
Barlows work.... but NOT perfectly and certainly not seamlessly....at this price point.
Also, magnification itself reduces image quality by atmospheric interference... when judging image quality of a Barlow, I recommend using it on your smallest magnification eyepiece... if you do not observe same reduction in quality as with already short focal length one when barlowed, then you might also be running in to having just too much magnification for the weather.
7:05 you almost dropped the eyepiece lol
Hahaha! I was hoping nobody would notice that..
What’s the point of a thread for a T ring if you can’t even fit a lens inside with the camera?
You don't need a lens with a camera attached, and adding a Barlow will double the magnification.
Hello, I think there is a mistake in description... When I trying to click on link to barlow, link transfer me to Svbony 40mm eyepiece :)
Nice review though
Sorted it my friend, sorry about that...
It's only 16£ or € I don't know which is which or $16 US as of Feb 2024 so I bought one and a nd filter
