Very nice binoculars. Especially for the money

It's nice to have so much more magnification than you standard 10x50 binoculars and for practically the same money.

Excellent binoculars at this price point

Excellent binoculars at this price point. Optical performance is quite good with sharp resolution near to the edges of the optical field.Collimation is problem in Celestron lower prices binoculars but is adequate in this purchase. Images are quite sharp and at 25 × and FOV is adequate for astromony. This binocular will be is splendid for terrestrial viewing, and adequate for astromony. You really can't do better in this price range. My other binoculars include Nikon, Fujinon and Cannon, way higher priced, so I am happy with this purchase and Adorama. They rapidly responded to my problem with a defective tripod adaptor supplied by Celestron.Recommendation... Splendid.

Great binoculars

These are really nice, had no problem adjusting focus of lens, great upgrade from my old 12x50, tripod works great for star gazing & animal watching, not really for lugging on hikes. Price was competitive, did receive emails to log back in and finish buying after I had already checked out. I finally did go back in and ended up ordering again by mistake, hassle to get order cancelled, but vendor did confirm double order was canceled. Other than that, all ended up good, really enjoy the binoculars.

Great Choice for the Price

Set up is easy. Night time objects appear bright and clear. A tripod is highly recommended since the binoculars are heavy.

WELL MADE

These binoculars are well made, the barrels seem the be aluminum with s rubber coating,the frame is also metal. The collimation was good on the set I received and the lenses seem to be clear and made from glass no visiable marks or bad spots in the lenses. The focus bridge between the eye pieces is also made from aluminum and not plastic like on some. The only dislike I have with these is the eye cups are useless, if you flip them down they are useable but they are too large and dont fit my face right, my nose seems to be in the way. The focus is good with just a little play. For a 25 power set they are clear and I have no problem useing them hand held for terresterial viewing.

Great Binocular If You Are Using Tripod

These binoculars are great if you plan on using a tripod to look at very distant objects or celestrial viewing. The image was clear and sharp. They also did well in low light. They are not great for bird watching or hand holding. Due to the magnification 25x and the weight of the binoculars, any slight movement of the hand causes the image to jump around.

Wonderful!!

The Celestron 25 x 70 SkyMaster was my very first purchase for stargazing, and I am very happy with them. There are infinitely more stars when you look through these binoculars. I bought them to view the comet Hartley 2. I had a lot of help finding it, but view it I did! Hartley 2 was gorgeous, and I also got my first personal look into the vastness of space. I love my SkyMasters and the tripod adapter is very helpful. I plan on purchasing a much better tripod but they fit onto the one I got for my camera just fine. A tripod is more than helpful as these are heavy and my hands seem to be shaky. I took them camping with me out on Lake Texoma and was able to watch people on the other side! I spent my Sunday checking out all the sailboats, and viewing the wildlife. I am so very happy with my purchase and will be purchasing my first telescope through Adorama as well. I hope to eventually learn how to take pictures of deep space.
