SVBONY 40mm Plossl Telescope Eyepiece - Fully Multi-Coated, 40° Apparent Field, 4-Element for Astronomy

Hi I bought 2 for my binoculars wasn't quite confident for the price.but better than some of my expensive eyepieces

Have not had the right conditions to try it out but am assured it will be a good addition to my other eyepieces.

Svbony produce great a lens, this 40mm is no exception, clean object view, excellent lens.

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!

Un ocular de buena construcción, sólido, ofrece vistas brillantes y generoso campo de visión, puede ser útil para quien use gafas pues tiene suficiente alivio. Muy útil. Tal vez el único "pero" es que, su angulo de visión al eje óptico, aunque suficiente, es algo delicado, esto es que si no estas bien alineado ojo-ocular se produce una sombra (kidney beaning). No es un problema por que así son los Plossls. Finalmente es un sobresaliente relación calidad-precio, si lo recomiendo.

Good product but not much useful in 1.25 inch barrel...because it can't show wider field then 32 mm due to limit of it's barrel

Produto de ótima qualidade .entrega super rápida
