Well made. Excellent quality. This is my second one, both are used as extensions on guide scopes.

As expected. Bought 2, for 2 Svbony 50mm guide scopes that needed extra back focus to stop my guide cams hanging off the end! As expected solid kit and works as needed.

Essential for SV MAK127 Necessary for the SV Mak127. Otherwise correct focus cannot be achieved.

Great 1.25" extension tube 1.25 inch extension tube, worked perfectly, tight compression ring; I'm using this to hold a QHY 5-III 462C farther from the scope since the NIR filter extends the focal point out quite a bit.

Affordable but well made and works erfectly I needed an extension tube so my QHY 5-II-M camera wouldn't fall out the back of my Orion 50mm mini guide scope. Even with the nose extension, I only had 1/4" of the camera in the scope in order to achieve focus. I have several SVBONY products and while they are definitely "entry level" in price, they have all performed exactly as promised and as needed. The extension tube is no exception. The fit is perfect, the finish looks fine and the threaded bolt to tighten the brass band that hold the guide camera in pace tuns smoothly and holds the camera without any play. I'm very happy with this fordable solution to my guide camera back focus dilemma. I highly recommend this product if you need an 1.25" extension tube.

Great productGreat product This extension tube has standard 1.25" diameter threads to attach filters or other components. I use this with a 0.5x focal reducer attached to the end, plus a light pollution filter. The threads seem high quality. This is a nice long tube that allows me to attain proper back focus for the reducer. I attached an image of how it fits into my setup -- the camera goes into the extension tube at the correct depth, and the extension tube + reducer + filter goes into the eyepiece holder, connected to the visual back. (I plan to test this without the diagonal as well, which should work theoretically). The collar of the extension tube holding the camera in place is secure and I didn't have any issues with it moving during my captures. I'm able to achieve perfect focus (using Bahtinov mask) from 0.5x to 0.33x reduction with no noticeable star aberrations. (Telescope is Celestron 8", camera is QHY5iii715C, and the focal reducer is from Apertura.)

Svbony SV154 2" 26mm SWA 70° Super Wide Angle Telescope Eyepiece

High quality at a bargain price I wanted a wide view eyepiece for my 80mm f6 refractor and the 2 inch 26mm SV154 certainly delivers that. I am also amazed what great build quality you get with this eyepiece. Highly recommended.

A nice surprise for astronomy beginners -- a bang-for-buck winner.A nice surprise for astronomy beginners -- a bang-for-buck winner. 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.

Svbony SV154 2" 26mm SWA 70° Super Wide Angle Telescope Eyepiece

A perfect first 2inch eyepiece. This is my first 2-inch eyepiece, and I didn’t realize how much of a difference it would make until I started using it. The wider field of view makes observing feel much more immersive, especially on the Moon and brighter deep-sky targets. The optics are sharp, contrast is very good, and the eyepiece feels solid and well made in the hand. It fits perfectly in my new 2in diagonal. Keep in mind though, it is heavier than a 1.25 in eyepiece, so you’ll need to be mindful of how it affects the balance of your OTA especially if it’s on something like a dobsonian. Regardless though, it aligns perfectly on each of my scopes, and makes manual tracking feel very stable. Eye relief is also comfortable, which makes longer observing sessions a lot more enjoyable. I’ve spent more time just casually looking through my telescope since getting this eyepiece because the views are simply more enjoyable and engaging. For the price, I’ve been extremely impressed with the overall quality and performance. I’d love to try out the SV136 or SV190 as well.

Decent lense Nice wide field lenses on a budget. Not a lot of magnification but great for the moon. Good starter wide field lenses.

It's an eyepiece 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.

Great first 2" if your tube can mount it. If you have a scope that can fit a 2" eyepiece then big yes on this. Its not too much, and compared to my scopes eyepieces this was a huge upgrade. Pros: -Great field of view -good quality lenses (to my untrained eye anyway) -Good eye relief (not hard to align your eye with it) I haven't found a con yet but ill update if i do. P.s. My wife has bad eyes and is the reason i was looking for a good 2". She was able to see ☄️C/2022 ZTF through this so i cant say we're disappointed. The image above is that same comet through the scope. If you're curious my Pixel 5 has a night exposure setting that allowed me to take that picture.
