For years SVBONY has been the king of the bargain astronomy hill, providing surprisingly good optics at entry-level prices. However, I’ve recently become quite enamored of Neewer, a new company trying to do the same thing. I jumped at the opportunity to compare products when I saw this set and ordered it immediately. Interestingly, these eyepieces each looked absolutely identical to their matching Neewer counterparts, and in all likelihood come from the same factory. However, I’ve seen this with both different brand eyepieces and binoculars and the actual glass in the product can vary — and of course is what really matters. However, in this case the bottom line is that Neewer was the one still standing at the end of this bout. Viewing bright crescent Venus, the closest round came with the 17mm eyepiece. Comparing it directly with a 17mm Neewer Plossl, the Neewer had a slightly crisper image and noticeably less optical astigmatism (lens flare). Moving to the 6mm eyepiece was a much more demanding and revealing test, and here the matching Neewer eyepiece was quite noticeably crisper and clearer for a solid win. With the 2x Barlow, again the Neewer was the victor with a slightly clearer and crisper image. However, the SVBONY Barlow actually seemed slightly more powerful, possibly 3x, and if that’s actually the case it’s not quite an even test. However, testing the SVBONY Barlow as advertised the Neewer won out. I will note that overall the optical astigmatism and other differences were noticeably less evident viewing Mars and Jupiter, but still more prevalent in the SVBONY than the Neewer eyepieces.There were other issues with this SVBONY set as well. Just one side note is that SVBONY points out that these 2 eyepieces plus Barlow will give you 4 different magnifications, but in reality you are simply not going to be using that 6mm eyepiece with the Barlow — the optical quality at this low price point is simply not good enough for the optical demands of that combination, and especially when used in a telescope at the low price tier that these eyepieces are targeting. So, you really only have 3 usable magnifications, and frankly it might have been better to replace the Barlow with possibly a 10mm or 12mm eyepiece. A couple other minor gripes are that the zipper on the case stuck at one of the corners making the case quite hard to open, and the filters were very hard to get out from the foam insert — anyone trying to use this set in the dark is going to have a hard time. Neewer has a very similar 9-piece set that includes 6mm, 12.5mm, and 20mm eyepieces and a 2x Barlow plus filters in a very nice case for about $15 more, and I highly recommend that set over this one. Also note that Celticbird is another new brand you will see at this price level, but I consider the Neewer products to be universally superior.The bottom line is that this SVBONY set still represents a good value (as their products always have) and earns all 4 stars, but Neewer has now planted its flag at the top of the hill. I hope that SVBONY will step up their game, and that I have the opportunity to test more of their product in the near future.

There needs almost to be three reviews of this kit—one for those who use their telescope only for viewing, a second for those who want to capture images and a third for users who capture images and enhance them with image editing software. Then, factor in the variables of capturing the image with a DSLR camera or a smartphone. With access to imaging software, the best result I’ve had is with my DSLR attached directly to the end of the main optical tube. Using the DSLR with a 90-degree diagonal mirror and the provided Barlow lens produced a large image acceptable for direct viewing. The Barlow was a game saver, using the same setup without it, the camera would not focus. There is not really much of a compromise using a smartphone compared to the DSLR. The optics is very good although the camera IMHO offers more and better controls. For my test photos, only terrestrial shots from indoors were possible, owing to the Upper Midwest winter weather. The kit includes three filters, an 82A light blue filter to reduce glare and enhance planetary details; a neutral density (ND) filter which similarly reduces glare and increases contrast; and a moon filter to dramatically reduce glare and brightness of the night sky’s brightest object. With my daylight test shots, the effect of each filter was subtle, however the purple fringing was not. With image editing software, fringing is easy to correct, although without one, disappointing. I am partial to the ND filter as, in the absence of a city light suppression filter, I think the natural colors of the cosmos should not be disturbed. That aside, the items in this kit appear to be high quality. Everything fits. Everything threaded tightens smoothly. And it comes in a molded foam, zippered carrying bag. The variety of the included filters and magnification levels of the eyepieces are useful and can be combined creatively to pique and sustain interest in the night sky.

I am admittedly relatively new to this stuff but done a lot of research and have caught on quickly. i am using a celestron omni AZ102. I wanted to acquire more eyepiece options and filters and a little more zooming firepower. After using these different eyepieces both on jupiter at night and for daytime terrestrial mountain viewing, i will say im not a fan of the barlow or the 6mm eyepiece, which was the main zooming upgrade combo i was after. The barlow tends to discolour what you are looking at (aberration issues im assuming) and i havent once felt i was better off for using it. Using the barlow with the 6mm eyepiece is rather discoloured and absolutely impossible to focus, and even the 6mm on its own hasn't given me a sharp view of anything. The 17mm eyepiece however was my unexpected surprise in this kit! it wasnt even the zoom range i was after but now it is by far my favourite lens out of all the ones i own. Feels and functions like it must be a step up in quality from the included 6mm lens. Although using the 17mm with the included barlow does look better than using the 6mm on its own, i still would rather just use the 17mm on its own and just go with clarity over zoom or just use the somewhat unimpressive 10mm that came with my scope. I havet got to trying the 3 filters yet but hopefully i get some use out of them, especially for moon viewing(moon hasnt been up at night here for the last week) . I would go 3.5 stars on this if i could because it is a decent value even with an item or two that i wont use, but ill go 3 just because in the end i think i would rather have just bought that 17mm by itself for less money. My next eventual purchase will be a quality single higher magnification eyepiece. The results with this barlow kind of makes me not want to try barlows at all anymore.

Como sempre a SVBony não decepciona. Muito bem embalado e cumpre o que promete. Totalmente compatível com o SVBony SV501p 60mm.O único porém é que achei a lente de 6mm um pouco escura no meu telescópio mas acredito que questão de algum ajuste de foco.

Very good eyepiece accessory kit. Works well and has lots of flexibility. Some of the pieces are a little light-weight, but they work well and it's a good value for the money.
