    • Excellent Barlow
Size: 3x
To my surprise, this barlow lens is very good. I was not expecting the build and lens quality to as good as it is for the price. What really surprised me is the optics. Very clear and has very little if any reduction in light transmission to the eyepiece, which I did not expect for such an inexpensive barlow. Highly recommend for anyone who wants a good quality barlow without spending a lot. UPDATE: I just wanted to add an update on some testing and comparison I performed with this Barlow lens and a GSO Shorty Barlow. First, you will notice that SVBONY has reduced the diameter of the barlow element, compared to the GSO Shorty. The reason for this is to allow full insertion of the lens assembly into a scope with a diagonal eyepiece socket. That is a good thing, as it prevents the barlow lens from contacting the internal diagonal mirror and damaging it. With the GSO, the barlow cannot be inserted the entire way to the housing stop, since it will contact or damage the diagonal mirror. I thought that this diameter reduction may also reduce the light transmission, compared to the GSO, but in my testing that was not the case. I found the SVBONY optics to be a little brighter and clearer than the GSO. My only conclusion is because this particular SVBONY 3x barlow has a THREE element vs the two element in the GSO shorty. The only plus I have found with the GSO over the SVBONY, is the ability to remove the barlow element and thread it onto the eyepiece. That gives an option to reduce the magnification from a 3x to 2.5x, something you cannot do with the SVBONY. For me, that is not an issue and I would still recommend the SVBONY over the GSO brand, due to its better quality element and better fit into any scope. ... show more

    • Good barlow, but for only $1 you can get one with a compression ring
Size: 2x
The optics of this barlow are perfectly fine, but I'd recommend getting the $17.99 2x barlow also offered by svbony which includes a compression ring. This will make sure that your eyepieces are not scratched by the tightening screw. They actually have 3 different 2x barlows for some reason, this one for $16.99, one for $17.99 with a compression ring, and another for $17.99 with a compression ring and t-thread. I'd recommend getting the one with a t-thread, it costs no extra money and it'll be useful if you happen to have/to get a camera that uses it. ... show more

    • Good low cost Barlow lens
Size: 2x
I have 3 Barlow lenses. This is a good low cost, Barlow. I purchased it because of the ability to remove the Barlow element and attach it directly to my zoom eyepiece for 1.5X. I rarely use it as a 2X Barlow but it works fine for that. Certainly, not a high-end unit which would be over $100, but for most purposes, it does a pretty good job at an amazing price. ... show more

    • Working just fine!
Size: 3x
Update: This works just fine (after modifying my focuser) and gives true 3x magnification (I measured it). ...the compression ring which threads into my focuser is not sized properly, and can wobble completely out of the focuser. When I was turning the zoom eyepiece, the compression ring was slipping out and getting cock-eyed. Teflon tape could get the threads to engage somewhat, but didn't last very long... What worked best was vacuum sealing silicon grease which is sticky enough to keep the compression ring static (as long as I use both hands when turning the telescoping lens). Original Review: I purchased this with a Svbony 7-21mm zoom eyepiece (which works great). Theoretically, the 3x Barlow + 21mm eyepiece should provide similar results to a 7mm eyepiece. However, I have found it to be unusable at night & tricky to use in the day. If my eye is even slightly off-center, the image completely disappears, and the image is noticeably cloudy. Note: Using this Barlow extends the eyepiece significantly... and will exacerbate any issues you may have with focuser alignment due to cantilevered weight. Hopefully using the Barlow will be easier once I get better a collimating my scope. ... show more

    • good value for a Barlow lens
Size: 2x
Used on a Newtonian 4.5" scope. Very useful for increasing the magnification of any eyepiece so that you may need only 1/2 as many eyepieces to cover a wide range of magnification.
