The Vixen Optics Geoma 9x63 ZCF Binocular is quite light for its bulging 63mm-diameter objective lenses. It yields an enhanced 9x magnification with a 5.4deg. field, which is easy to observe all at once with your mind's eye. Eye relief is plentiful at 21mm and you can attach the ZCF to a tripod, car window mount, or monopod if needed. The Geoma makes for a dandy astronomy viewer, showing you lots more stars than 42mm or 50mm binoculars.
