Input:
The binoculars don't have good optics. The crystal is BK7, the economical type.
Better look for crystals type BK4 which are used in more expensive binos. The Celestron Upclose 20x50 is O.K. The sight is not as clear and good as the Celestrons Skymaster 15x70 or the 25x70. I have tried all these 3 binoculars and prefer the Skymasters but they tire you up after a few minutes. If you are looking for binos with good magnification and not very expensive, save until you have enough to buy one of the Skymasters. On the other hand, there are other binoculars out there. It is a matter of personal choice. But I advise you to shy away from the
the Celestron Upclose.
