SVBONY SV135 Zoom Eyepiece, Zoom 7 to 21mm 1.25 inch Telescope Eyepiece, 6 Element 4 Group Telescope Accessories for Astronomic Telescopes Visual

Fantastic Value – Versatile and Clear Views! I am very impressed with the SVBONY SV135 eyepiece. For the price, it’s an absolute gem. The zoom range from 7–21 mm makes it incredibly convenient—I can switch magnifications without fumbling with multiple eyepieces in the dark. The zoom action is smooth, and the build quality feels solid and reliable. Optically, the views are sharp and clear. The Moon looks crisp, Jupiter’s bands are visible, and I was even able to catch details in the Orion Nebula. The eye relief is comfortable, and it works well with or without glasses. Of course, the field of view is narrower at the low end (21 mm), but it opens up nicely as you zoom in. For me, that’s a small trade-off considering the convenience and performance it delivers. Overall, this eyepiece has quickly become one of my favorites in my kit. Whether you’re a beginner or just want a versatile grab-and-go eyepiece, the SV135 is hard to beat. Highly recommended!

Used this on a little grab& go scope. Plenty good enough. Don't expect Nagler quality, but comparable to most Plossl eyepieces

I noticed early on after receiving this SVBONY eyepiece that something didn’t seem quite right—there was a broken plastic piece on the bottom end. I wasn’t sure exactly when it broke, but once I realized it, I contacted SVBONY’s customer service. They were incredibly helpful and responded quickly. Their warranty service was excellent—they sent me a replacement eyepiece within just a few days, completely free of charge, including shipping. The eyepiece itself looks great, feels good in the hand, and performs well. The views through the telescope are sharp, and while there are eyepieces with wider fields of view, this one is still very versatile for what it offers. I mainly use it as a planetary eyepiece, and it works really well for that purpose. There are some plastic parts that could potentially break, as happened with mine, but knowing that SVBONY stands behind their products with such solid customer support gives a lot of confidence. Overall, a very nice eyepiece backed by exceptional warranty service. Would recommend.

This eyepiece helps cancel/absorb some light and allows for more clarity when viewing in the suburbs. (My backyard) After about 5 min adjusting eyes, many more distant items became visible with this eyepiece, than any other I have. The ability to zoom with 1 piece eliminates the hassle of changing, dropping, or looking for the next piece you want. Price point; this is a very good product that can replace 5 other eyepieces, or save some cash by only getting this 1 zoom. Happy star hunting.

Very well made, another SVbony quality product !

very good quality and works great. highly recommend

To be fair, I don't have any experience with other Zoom eyepieces, but this SV135 model from SVBONY works very well. The title to this review is because you get 5 different focal lengths from 7mm to 21mm, and you can figure out what works best for you before you spend more money on individual eyepieces. Solid weight so it doesn't feel cheap, and very smooth movement when you twist to zoom. It comes with two rubber dust caps that fit nice and snug without being difficult to remove. Views through the eyepiece are sharp and clear, the only downside is you will need to adjust your telescope focuser slightly. There is also some reduction in field of view (i.e. how much of your target will fit in the eyepiece), but that isn't an issue. I have a few different products from SVBONY, and I am always impressed with their quality. If you are on a smaller budget, I highly recommend this zoom eyepiece.

Looks amazing at 21mm. Maybe I'm broken, but zooming in, becomes harder to focus. Used on Reflecting, refraction x2. Buying a 5mm now since I can't see with this 7mm

Bought this to save swapping out eyepieces all the time. The focal range is great, the image is clear and it's very comfortable on the eye when viewing. I think it's exceptional value for the quality of the build and image through the eyepiece, and I'm finding this is my go-to eyepiece at the moment because it's so convenient. Well worth the money.

Un buon prodotto anzi ottimo per il prezzo che a

Sympatyczny maluch. Oczywiście jak każdy zoom zabiera trochę światła, ale poza tym optycznie jest co najmniej dobry, a biorąc pod uwagę cenę, nawet bardzo dobry. Lubię w nim płynną, a nie skokową zmianę powiększenia, dobrze dobrany - ani za mały, ani za duży - opór "potencjometru", całkiem spore pole widzenia i dobrą ostrość (najlepsza przy ogniskowej circa 16 mm), mechaniczną precyzję, no i to, co w każdym zoomie - brak konieczności zmiany okularów.

perfeito!

I used this zoom lens all the time, Finding objects at low mag, then zooming into high mag to look closely at the details. Way easier than changing a lens and losing the object. However, the zoom is a bit tight, and I find best to hold stationary with one hand while turning the zoom with the other.
