Great beginner eyepiece set

So I'm relatively new at this hobby but I've done a good amount of experimenting with eyepieces. To make a long story short, this eyepiece (6 mm) is better than a similar one I paid $100 for (orion). I would feel comfortable telling beginners to just get the whole set of these and call it a day. Don’t bother with a barlow, at best they can magnify the image for you without degrading the image quality but it will NEVER make it better. Unless you’re going to spend over $100 on a televue barlow, seriously don’t bother. If you buy the whole set of these, you won’t need one. Don't spend a ton of money on expensive eyepieces until you get a chance to look through these yourself. These ones have a nice wide view opposed to looking though a pinhole on the plossl eyepieces that most scopes come with. They also have good eye relief so you can really put you eye up to the lense without your eyelashes getting in the way and is especially important if you wear glasses. The picture I am attaching is through a 6 inch skywatcher telescope, and this very eyepiece (6 mm) with an iPhone. Enjoy, these are a fantastic value.

Good value, quality can be hit or miss, but the seller has great support

Great value, I wish I knew about these when I first started. It's a good set that covers a useful F/L range. The decent 66° afov makes viewing much more enjoyable than typical bundled eyepieces. Most of these where reasonably well corrected with my 10" f5 scope and produced pleasing and comfortable views . But my 9mm is bad, it has horrible pincushion and comma over 80% of the view. It is so much worse than the others that I think there must be an assembly issue with it. There is no way it is supposed to perform that poorly compared to the rest of the set. Hopefully the seller will offer trouble shooting or replacement, otherwise I will search online to see if it is possible to adjust the lens groups or something. EDIT: After writing the review, a replacement 9mm showed up on my doorstep. No questions asked. Great support by SVBONY. I've changed the review from 3 to 5 stars. This set really is a great value for a new scope owner.

Best Low End Eyepieces on the Market (Under $40)

Best Low End Eyepieces on the Market (Under $40) After examining and testing Meade, Celestron and SVBONY, in my opinion SVBONY is hands up better than the other two eyepiece providers. My ranking is SVBONY, Meade and Celestron, in that order. I did not examine Orion eyepieces. This is based on their 6mm, 9mm and 20mm eyepieces. Of course SVBONY eyepieces can not be expected to match the higher priced, better quality eyepieces made for Meade, Orion, Celestron or Tele Vue but they are a good bang for the buck. I would rate SVBONY eyepieces a 5 for the under $40 market and a 3 overall when compared to the quality ones. The best feature of the SVBONY wide angle eyepieces is their great POV; however, a caveat comes with this and that is you need to have the object you are viewing centered in the eyepiece. Here are Pros and Cons of the SVBONY wide angle eyepieces: Pros - great field of vision and if you have the object centered in the scope good clarity - appears well constructed - reasonable price for what it is supposed to offer - good value for the money Cons - very heavy. If you add a heavy barlow lens in all likelihood you might not be able to mount a cell phone or camera to the scope - chromatic aberration and comas if the object is off to the side of center in the scope

A solid set of starter/budget eyepieces

These are my main eyepieces for use with my 130mm AWB OneSky, especially the 9mm and 15mm. The 9mm is nice n' bright, even with the SVBONY 2x Barlow (I use them together for planetary viewing), and the 15mm is my mainstay for viewing nebula, clusters, and galaxies. My 6mm was giving me a little trouble, but SVBONY proactively reached out to me to replace the defective component, and now I can properly review it: Last night I put the 6mm on my 2x Barlow and split the Double-Double into with ease. This combination runs up against the diffraction limit of my 130mm AWB OneSky, giving me nice clear Airy discs around my stars. Conclusion: The full 4-piece set is *definitely* worth the price!

I would like to give it 10 stars!!

I have some kellner and plossl eyepieces. I also have Barlows 2x and 3x. And now I have this amazing eyepiece. What you read from some critics about the characteristics of lenses and Barlows, will too often confuse you and often will lead you astray from buying a great piece of equipment that you probably would thoroughly enjoy if had not decided to forego the purchase based on their opinions. I truly believe that some critics opinions are simply parroting what others have said for fear of reprisal, and they have never really tried the product themselves. For example, I have found that the 3x Meade Barlow has become my most often used attachment. It is superb and I don't even use my Orion shorty 2x anymore. The so-called loss of light compared to a 2x is nonexistent and not worth talking about when you are using it out in the field. Also, I see no difference in my Plossl vs. Kellner. Yes, the eye relief for the plossl is closer to the eyepiece but it works so much better when I attach that lens to my android cell phone camera. I can just set the lens right on the camera lens with the holding carriage (the optical lenses on both are recessed and won't get scratched) . You don't need to adjust the lens position away from the camera due to a longer exit pupil found with a non plossl. Now lets talk about this Ultraview lens. You would almost think that something has to give if you are using an eyepiece that is going to give you good eye relief with wide viewing at only 6mm! I bought it for the sole purpose of finding out what have they given up to achieve all of this. They have given up nothing. This lens has an amazing wide view, good eye relief with quality clarity that even excelled the same power with any other combinations or single lens that I have. The lens is a longer device even longer than my 3x Meade Barlow. The only negative about this lens is that it will take almost one month coming from China before you have it in your hot little hands. Your patience will be rewarded. This lens will make some of my other combinations go onto the shelf. As I use it more, I will find out what new combinations will work best and quicker in the field.

Epic starter set of eyepieces!

image quality is pretty much as good as you can get for this price of eyepiece kit. very good value for the money. Image is VERY BRIGHT and razor sharp with no noticable CA. coma on fast telescopes will be strong but not really much of an issue. will be negligible on slow telescopes F8 and up. image quality would likely be impeccable on slower telescopes tested with 100mm F4 reflector telescope. I would imagine the image quality would be absolutely outstanding in an apo refractor telescope. or a good quality achromat telescope.

Worth every penny

Amazing cheap eyepieces. I have celestron plossl eyepieces of the same focal length. These cheap little wonders provide an image just as sharp as the celestron plossls with amazing wide eye hole (better field of view and better eye relief). I was doubtful that these eye pieces would be that great but for the price they are 100% worth it. Upgrade your plossls for cheap.

Not bad, even at f/5

I was looking to upgrade from orion Sirius plossls, which in their own right are very capable optics. the reason I chose these were for their feild of view and numerous recommendations from amateur astronomers. after purchasing, I read that these wide field eyepieces preform poorly on faster scopes, think f/5 and faster. in practice, on my f/5 reflector, they work beautifully. i collimate my scope regularly, almost religiously, and they perform amazingly! a slight slight coma on the higher mm eps, but at the lower mm, it's not as apparent due to the smith type "barlow". to be fair, i have not used televues or naglers, but for a beginning enthusiast on a high f/#, do not hesitate! in summary, these relatively cheap eyepieces perform as expected or better on fast scopes, and amazingly on slower ones. the wider field of view is important for starhopping, and can translate into spectacular views.

Great economy eyepiece.

NOTE: I AM ONLY REVIEWING THE 20 mm EYEPIECE. Good eyepiece for the price. Good field of view. It does "kidney bean" a bit (crescent shaped blackouts near the edge). This is just the way it works I think, and all you really have to do is center your eye in precisely the right place to see the whole field of view. I saw a full moon with it and it looked quite sharp. No chromatic aberration that I could notice. I took a look at the Andromeda Galaxy in a light polluted area, and I could see something. I have not taken it out to the countryside yet, but I am certain that this will give great views of nebulas and star clusters.

Great for the price

These are great eyepieces if you're on a budget! The 6mm and 9mm are great for viewing planets, or if you want to get real close up on the Moon. The 15mm and 20mm are great for a lunar overview and some deep sky objects. Overall a great set to have.
