SVBONY Telescope Eyepiece 34mm, 2" 72° Super Wide Angle Telescope Lens, HD

Whoa. I spent a long time on forums and talking to other astronomers before making this purchase, and in the end I only chose this eyepiece because it was the only thing that would arrive in less than two months. I was worried that svBony would be some mediocre chinese glass but I am pretty impressed. I've been to a few star parties so I've looked through the explore scientifics and I gotta say this isn't too far off, especially when considering the price. There is *very* minor chroma near the edge of the field (outer ~15%) but the center view is stunning. My first test was the moon in my 10" f/4.7 dobsonian and it really was a whoa moment. Before this it had just been done super plossls so the difference was absolutely stunning. The crispness in the image was beyond belief, with edges clearly defined and no visible abberation at all in the center fov. It definitely gives the often mentioned "porthole into space" feeling and I was instantly in love. Half the time I find myself barlowing this eyepiece rather than using my new high power eyepieces because the clarity is so impressive. DSO's are very noticable from the deep everglades and I was able to just make out some detail in the spiral arms in bode's (m81) I can say to anyone worried about QC that the eyepiece doesn't leave much to be desired!

I like this eyepiece a lot. It is great for maximizing the field of view in a Celestron C-8 SCT. It has close to the maximum fov when used with a C-8 equipped with a 2" diagonal. It is very nice with little or no vignetting. The maxi fov on a f-10 C-8 SCT is about 1.3 degrees and this eyepiece yields 60X magnification with a fov of 1.2 degrees and it is a very pleasing image. Definitely a thumbs up!

I bought this 34mm eye piece for a little lower power and a wider field of view. I have an ES 30mm eyepiece at 70 degrees that I like but this Svbony 34 72 degrees is just a little better to my eye. Of course it all depends on the telescope you're using, I like to use slow telescopes f/11 and slower, in my 90mm refractor f/11 it works fantastic! I even masked down the aperture so it's now a 70mm but that makes it now a f/14 which is great on all eyepieces.... Now all you people with fast Scopes like f5s and faster it probably won't be that great, that's why I don't use fast Scopes anymore they're just too rough on eyepieces no matter what they are. So my 90 mm refractor with the 2-in diagonal and 2-in eyepieces is a great view to behold, Stars look good to the edge, and it really looks like a 72° field also, and the box it comes in reminds me of Tele Vues boxes. Good job Svbony.

I have an 8 inch f6 Dob telescope. This eyepiece provided a nice immersion experience when viewing Large star clusters (M45) Nebula (M42/43) and galaxies (M31/33). Good on-axis view. Some distortion noted at 70% out from the center of the view, with astigmatism producing seagull-like distortions at 90% out from center. You may want to consider a more expensive eyepiece with more lens elements if you telescope has a focal ratio less that f6. If you are an eyepiece perfectionist, this eyepieces is not for you. But if you want an immersion experience at a modest scope, this is a good eyepiece to consider.

Inexpensive, and surprisingly good for the money. I’m using this and the 27mm eyepiece from the same series for low power sky sweeping and comet hunting with my old TeleVue Pronto telescope. This eyepiece delivers 14x with the Pronto, which is ideal for large objects like M31.

Good bargain low power eyepiece! Would buy it again. Using it on a 12” Meade LX200 SCT.

You usually get what you pay for. I am relatively new to astronomy and own both an 8-inch Dobsonian and an 8-inch SCT. I purchased this eyepiece hoping to find a quality, affordable SWA low-power option, but, honestly, you generally get what you pay for. As a newcomer, I expected good value, but it didn't meet those expectations. The build feels solid and doesn't seem cheap, but the optical performance reveals its budget origin. Center views are sharp, clear, and high contrast, but off-axis and near the edge, there's significant coma and kidney beaning. These issues appeared in both my SCT and Dob. You pay for a 72° AFOV, but only about 50° is usable. I seek value, and this was a poor investment, so I returned it. For a slightly higher price, better options exist—like an 82° 20mm Explore Scientific eyepiece I found used, which offers a better viewing experience in both scopes. If your main concern is low power and edge performance isn't critical, this may still be suitable. Don't get me wrong, the build quality is very nice and doesn't feel cheap. However, when looking at the night sky, its budget deficiencies become immediately apparent. On center, the views are great—sharp, clear, and with good contrast. But off-axis and toward the outer edge, there’s a lot of coma and kidney beaning. These unimpressive results appeared in both my SCT and Dob. You are paying for a 72° AFOV, but you can probably only use 50°. I am always on the lookout for value, and this just feels cheap and like a waste of money—so I returned it. Depending on your needs, at this price point, there are better options available for slightly more money. Ultimately, I purchased an 82° 20mm Explore Scientific eyepiece used for a little more and have been much happier with the quality of the view in both scopes. If you’re looking for a low-power eyepiece and aren’t concerned about the outer edge performance, this could still be a good fit.

In a world of “astronomically priced” eyepieces these svbonys are great value for money. If you are a perfectionist with Superman-like vision go buy the $800 ones….

Se siente robusto y su óptica es de califad

I use this to explore the sky with my 8” dobsonian. It gives a nice wide view and a clear picture. For some clusters of stars, I prefer this over my more powerful eye pieces to take in an entire view

This is my new go to eyepiece. The views are great, really bright exit pupil, obviously depending what scope you use it with. Really nice to use and with a barlow lens can give a nice zoomed in view with a lot of eye relief. Really comfortable to use.

Do not hope for the quality of view of a Televue with this one. But for the price. It does the job really well! Great build quality, easy to clean, large view, folding cup. Perfect for starting with DSO :)

Je suis insatisfait, pas pour la largeur de voir mais la netteté n'ai pas au rendez-vous c'est comme si il y avait une voile à l'intérieur qui empêche de voir clairement le ciel et c'est vraiment désagréable, Maintenant je ne peux le retourner vu que je ne pouvais m'en servir avant le temps du remboursement. 😢
