SVBONY SV154 Telescope Eyepiece 2 inch Super Wide Angle Eyepiece 70 Degree 26mm SWA Eyepiece Telescope Accessory for Astronomy Observation

When you read online astronomy forums, people make it seems like you have to spend $$$ on a televue or a baader to be able to see anything out of your telescope. They bash svbiny a lot as cheap garbage. I can confidently say, this is a great lens, and as a normal amateur astronomer with normal eyes living in a bortle 5-7 area, everything looks crisp, clean, and beautiful through this lens. I love the immersive wide field of view. This a fine lens! Dont let the snobs convince you to spend 3 times the price on a lens that is supposed to be better but offer barely any noticeable difference for the extra cost!

I'm switching over to the 2-in size eyed pieces so I bought this 26 mm and it's been a really good eye piece, of course it matters what type of telescope you're using, if you're using a fast telescope like F/5 then you're going to have some problems on the edges but all my telescopes are f/10 and above and it works quite well in those, there's still a little distortion on the very edge but not too bad. I also use this eyepiece during the daytime and it does quite well so it's really a good quality eyepiece for the money. I've got two of them now so I'm a happy camper.

I skeptically purchased the SVBONY 154 26mm expecting many flaws for such a bargain price. I've owned the legendary 24mm Panoptic eyepiece for 15+ years. (The 24mm is so good, it's used price is steadily increasing, not declining, over time.) But the SVBONY 154 was great in my 8" f/10 SCT. I was stunned how sharp it was. As far as I could tell, the promised 70-degree AFOV was correct. I can imagine doing an entire astronomy outreach program just using the 154. Some comparisons and limits: The Pan weighs 8 oz vs the 154's 11oz. The 154 is a 2" eyepiece so any filters would be 2" also ($$). Of course, the telescope would need a 2" focuser. I can report that the 154 works fine in the popular photography adapter, NexYZ. I'm a little concerned about the eye-cap. It should be fine if you don't switch it between eye-mode to glasses-mode. But it's more stiff than most eye-caps and so it might not tolerate frequent adjustments. A good eye-cap is essential when viewing from an illuminated location. There are many high-quality 24mm-26mm eyepieces on the market. But the SVBONY delivers an amazing view for a novice-friendly price.

To start, I would say this eyepiece blew me away. I’m in college and doing astronomy on a tight budge. This eyepiece came exactly as advertised! I own a 12.5” f/5 dobsonian telescope and the views were fantastic. The eyepiece gave a full 70 degree field of view and through my telescope it provided me 1.14 degree true field of view. This allowed me to see large objects like the complete double cluster, M81 and M82, M108 and the owl nebula, and most of Andromeda. It also split the double stars of Mizar and Albireo very nicely. Globular cluster were especially good and I could see individual stars in most of the brighter Messier ones. I could also see the distinct dark lines in M13. Granted I have a telescope with a large aperture which really helps, so keep that in mind. The moon was also amazing! I could get then entire full moon in the eyepiece. Now the down sides to this eyepiece. The edges of the field of view were not as sharp as the center.. You can kinda see that in the picture of the double cluster I added. However, It wasn’t horrible but definitely noticeable. It’s also quite heavy and I had to readjust my telescope’s balance. If you can live with those, this eyepiece is a steal. Overall, this eyepiece is of high quality and my go-to out in the field. Recommending this to anyone on budget looking for amazing and affordable views.

Good quality telescope piece. It fits well and has good clarity. Very easy to use.

I had other more expensive eyepieces in my list but after some positive reviews decided to take a chance on Svbonny. My thinking was for $58.00 if it doesnt perform, I'll return it, right? Boy am I glad I went with Svbonny. The eyepiece is well constructed, eye relief is confortable and the views are shrap and crisp and clear. Images are shrap to the edge of the field focusing to sharp diamonds on velvet. I use it on a 60mm F7 achro, an F10 C11 and 10" F4 Newtonian. Recomend 100%.

I purchase the 15mm 70 degree eyepiece, well made,great field of view, sharp clear images With a budget price.

Fabulous wide angle image.

Echt gutes Okular. Warum hat Svbony nur 2x 2 Zoll im Angebot? Habe beide und würde sofort mehr 2 Zoll okulare kaufen. Top Empfehlung. Auch im direkten Vergleich mit Celestron, Omegon oder Skywatcher okularen echt top. Gegen Baeder und TeleVue zwar keine Chance aber die Kosten auch das fünffache. Für Anfänger top Produkte.

Lastima que no haya mas cosas para 2 pulgadas Como filtros o prisma 45 grados.

This eyepiece is just an eyepiece, but it feels really high-quality. It has a lot of weight to it, and it acts exactly as it should. Great price for the product.

I compare this to my Saxon 21mm SWA (68 deg). The Saxon definitely has less coma than the Svbony (seen through my f5 dob)! That is pretty much the only complaint I have about the glass in this eyepiece, otherwise the centre of the image is clear and sharp. The outer build quality isn't that high comparable to the Saxon but that doesn't really matter (things like rubbers slightly overhang). Eye relief is fantastic and is great for the price you pay. I am pretty sure that the SV154 is just a carbon copy of the GSO SWA but sadly cannot compare. No regret buying this eyepiece for the price can nearly get the entire of subaru/pleiades into the eyepiece.
