SVBONY 25mm Telescope Eyepiece, Large Aperture Eyepiece, 40 Degree Field of View Plossl Eyepiece with Filter Threaded for Observing Moon Planetary Binary

I didn't pay very much for this eyepiece, so I was really surprised to see how good it was for the money. I bought it primarily for stargazing. I wanted to bring the power on my 70mm Celestron spotting scope down to 10X (the longest focal length stock eyepiece it came with was 20mm, or 20X).This eyepiece produces a clear, sharp edge-to-edge image of stars, with no signs of optical aberrations. I tested it during the day for terrestrial viewing and found it to produce a sharp image as well. I'm also really pleased with the wide field of view.Good eyepiece!

Good eyepieces considering the low cost, but too much vignetting for my Denk binoviewers in a 900mm FL 120 refractor. This is not a problem with the eyepiece pair. I was just pushing the limit for widest FOV and looking for lowest mag, but it didn't work.

Great bargain. It's fully multi-coated, and it has a good image and build quality. The only drawback is the poorly defined field stop, which makes the edge of the field of view undefined and out of focus.

I like this item. A great addition to the current lens!

Quality is absolutely grade A. The wide field of view makes finding objects easy.

Great quality

I bought this to attach to my camera that is connected to my telescope. The images come out greater than before! Also, it's a lot clearer when attached to the telescope it's self. I am actually planning on buying another. One for the telescope and one for my camera lens attachment.

Nice wide angle full capture, clear, and closer for the eye too see.
