SVBONY Telescope Lens 4mm Telescopes Eyepieces Wide Angle 62 Degree Aspheric Eyepiece Fully Coated lens for 1.25" 31.7mm Astronomic Telescopes

Good quality, I could see Alpha Centauri A and B both with this eyepiece on the other hand 20mm and 10mm eyepieces couldn't separate this twin star adequately enough. Cons: I found a small dark spot in its optics but it did not hinder the view substantially. Will try it on Jupiter and Saturn asap. Bang for buck

Nice to eye relief

Excellent. Center portion CA well controlled. Nice to see highly magnified image, pls note brightness will reduce according to magnification

I tried it for several nights. Tried to capture mainly 3 planets. Jupiter, Saturn, Mars. Saturn was a bit blurry but you could identify the rings and the gap between rings and planet. Jupiter and Mars were blurred like you are focussing on something very close, and the image was never narrowed down to a sharp image.
