Review: Amazing quality - I'm very impressed. This was my first SVBONY purchase and I must say the quality is mind blowing for the price. The eye piece itself is comfortable against the eye. It is strong and sturdy and well made. The lense are clear and free of any imperfections which leads to amazing photos and videos with extreme amounts of detail. This is the first SVBONY of many I will be purchasing. I already have a few others in my cart.
Review: Surprisingly Good! - Really surprised at the overall quality of this very inexpensive eyepiece! Really good apparent field of view (AFOV) of 62 degrees and sharp stars across the entire field. Only thing that could be better is the eye relief, to get the full AFOV your eye has to be very close to the lens. However, this is the 4mm which is a high power eyepiece and the eye relief for this level of magnification naturally won't be good. But still, the nearness of my eye to the main lens is not THAT bad and again, very pleased with this product.

### ⭐⭐⭐⭐ Excellent Value and Good to better views.
*by R***B on January 15, 2019*

I used all three of these eyepieces (EP) in my 8” SCT f10; 4” MAK and fast 60mm f5 telescopes. Yes these are light, plastic and inexpensive but don’t let that stop you because these are a true value and I would highly recommend these to 99% of the amateur astronomers. I did a lot of research on the forum outside of Amazon, out there I saw mixed reviews, I agreed with some points especially on the 10mm. For my review I compared my expensive 8.8 and 5.5 Meade SWA EP’s to the 10mm and 4mm. For the 23mm I used my ES 24mm. I viewed on three different nights with good to poor seeing as well as daytime. The 23mm was excellent for day and night. Under dark skies I could hardly tell the difference between my expensive ES 24 and this eyepiece. The ES provided more contrast and darker backgrounds, but the brightness was very similar. Under a bright moon there was a lot of glare off axis, but the view was very good or better when on the objects. I viewed the Orion Nebula, Pleiades, Jupiter and our moon and the view was very good to excellent in all three scopes. The 24 ES cost more than 10 times this EP and so I would highly recommend this SVBONY EP to anyone, even the most critical observers. The 10mm was good to fair in daytime for terrestrial viewing. At night under dark skies the 10mm did not perform very well. The 10mm works ok for the moon but for deep sky the EP was not good. You could argue that comparing this to the Meade 8.8 is not a fair assessment, but I keep the same methodology for all three EPs. The 10mm was dimmer than my Meade 8.8 and did not provide good contrast on all objects in either my fast f5 or slow f10 telescope. Because the 8.8 provides more magnification you would expect the Meade to be the dimmer EP but the 10mm was dim and not sharp. The view in my 4 MAK and 8 SCT scopes was more poor than good. I would think that my slow scopes would be more forgiving, and this eyepiece performance would be better. The view in my fast 60mm was poor which would be expected. I have read similar experiences in the astronomy forums, so my n assessment is not a surprise. Having said all of this you really can’t beat this value of this EP and although I would not recommend the 10mm to everyone, it was certainly useable and probably an upgrade to the vendor supplied EP in less expensive scopes. The 4 mm performance was a surprise and was good for day and very good for night viewing. Under dark skies I could tell the difference between my expensive Meade 5.5 and this 4mm but unless you are using expensive EP’s most people would not notice a big difference. You will notice that the 4mm is taller than the 10mm and perhaps this design explains why the 4mm performs so well compared to the 10mm. What surprised me more was that the EP worked well in all three scopes, slow and even the fast 60mm f5 scope. Some reviews in the forums were very negative about the 4mm but I just could not see the problem. Perhaps it’s because 4mm is high magnification, the eye relief, tripods and mount steadiness, and your telescopes optics impact views at high magnification. My fast scope was inexpensive and has an unsteady tripod but my daytime bird watching and views of the moon and were very good. In the 4mm the views of the moon’s craters were sharp and well defined in the 4mm. Even when comparing to my Meade 5.5mm EP the views were comparable in the 4. Meade has a wider 82-degree view so it was easier to find items in the Meade. In some cases, the view was better in the 4mm than my 5.5 even though the 4mm provided more magnification. You would expect the 4mm to be dimmer than the 5.5 but it was not. I was surprised that the 4mm EP provided good views in my larger slow scopes. For deep sky objects the views were ok; its hard to tell at high magnification because higher power usually means dimmer views and its easier to see deep sky at lower powers. I did take a peek at Orion and the Pleiades and the view was ok. I was unable to test the 4mm on any planets but I would expect the views would be good. Overall, I can recommend this set of Eyepieces although I would probably not buy the 10mm again unless I needed it for a kids viewing session. The 23mm was surprisingly good, too good for the money. I would recommend the 23 to anyone and will probably by this again for my finder EP or binocular viewing. Certainly, if you don’t have a lot of money and need an upgrade buy the 23mm you will not be disappointed. The 4mm was surprisingly sharp and worked very well on the moon. Even with the 10mm performance issues this set of three is well worth the money.
