Ratings & Reviews+

Celestron SkyMaster 20-100x70 Zoom Binocular is rated 3.388888888888889 out of 5 by 18.
Rated 1 out of 5 by from Disappointing I tried these and compared them to the Celestron Skymaster 25x70. These have tunnel vision when zooming in and were really difficult to focus. Not as clear as the 25x70 which show the view much more clearly and almost the same distance without the zoom. I took these back and keeping the 25x70 pair.

Rated 1 out of 5 by from Tunnel Vision I have a pair of Celestron SkyMaster 15x70 binoculars and love them. These looked like a complementary set which I looked forward to receiving. A couple of poor reviews expressed concerns but I thought I would try them since many others were positive. Well, with great disappointment, the poor ones are correct. Although the optics were clear, when compared to my existing binoculars, these are like looking down a narrow tunnel, the type of effect you get looking through binoculars backwards. As mentioned elsewhere, when zoomed in, the viewing field is further obstructed by the magnifying lens. I returned them immediately.

Rated 4 out of 5 by from good product It was a gift for my son. He loves it! The only thing is that they are heavy to hold and you need a tripod to be able to hold steady. Otherwise shaking hands make it hard to see stars. I would buy this product again! Definitely worth the money.

Rated 4 out of 5 by from Great binoculars for the price Very good binoculars for the price. A bit heavy at 3 pounds and better used on a tripod. Optics are very good and there's a no fault lifetime warranty that's rarely found anymore.
