The UpClose G2 20x50 Porro Binoculars from Celestron has a traditional Porro design with BAK7 glass and multi-coated optics; creating a viewing experience of clarity and high contrast. The combination of the 50 mm objective size with 20x magnification delivers the largest binocular size that can be hand-held without too much shaking and without a mount. Of course a 50 millimeter objective has enough light transmission to be used successfully in low light conditions and the high 20x brings in the details of distant objects. This is a good size binocular for scanning the night sky for celestial observation. Rubber covered aluminum with indented thumb holds and finger ridges provide a protective non-slip grip and added protection for the housing and optics. Coupled with a wide-angle FOV, this binocular produces an all around scope for sports events, hunting, nature walks, astronomy or just visually inhaling outdoor panoramic vistas.

Celestron UpClose G2 20x50 Reviews
Hard to focus
It’s difficult to focus on far away objects. I see double. I have to close one eye not to get dizzy.
Mine do not stay in focus
Bought these last summer in preparation for viewing solar eclipses and limited night sky viewing. I find the build quality to be rather poor. The diopter adjustment slips and I find myself constantly having to readjust the diopter. Usually one eye is out of focus, even when the diopter is adjusted. I pulled back the rubber sheath and tightened the focus adjuster, which helped considerably. But I find they come out of focus very easily, even with hands free use when mounted on a tripod. I think 20x50 is the ideal compromise for a compact, solar eclipse viewing binocular. But I will be testing out the Vixen SZR 20x50 this week in advance my next eclipse chasing adventure. Another problem with these, which is for most in this format and magnification, is that it is difficult to fit threaded solar filters on the front. I tend not to trust a slip on filter, opting always for the security of a fully threaded safe solar viewing filter. I was able to peel back the rubber around the front objective and force a 55-77mm step up ring into place that allowed me to use my set of 77mm solar filters. The fit is tight, and skewed. Would like to thread the plastic barrel, otherwise will likely epoxy the step up ring into place. And since the rubber lens caps never stay on, this will give me a way to secure a better fitting lens cap. Both front and rear lens caps fall off when I place the binos in the included, very cheap, fabric case. Can not recommend these binos. They are not useful hand held (nor are any 20x50 optics), they do not stay in focus and lens caps fall off.
