The Celestron SkyMaster 25x100 binocular offers big-binocular performance at a great price! Huge 100mm multi-coated lenses let in lots of light, and 25x magnification provides high resolution views of both astronomical and terrestrial targets.

After reading many online reviews and comparing prices and features, I settled on the Celestron SkyMaster 25 x100 for its lenses, its magnification and its price. These are not for taking on a trail. They are large and heavy - a little clunky-looking actually- and require a steady tripod.

Well I have to say they are worth every penny. day time viewing is very crisp and clear. night time view`s are just as good. very good product.just make sure you have at least a heavy duty tripod.these bino`s are a bit on the heavy side.

Nice quality, very powerful. Yes, as the other ratings say, you WILL need a tripod, but that is what you get when you buy a serious set of binoculars. Amazing value!!

Saturn is very clear with rings, (small yellow ball with a line through it) optics are ok for the money. They are heavy! must have a good hd tripod. focus is done with each eyepiece. these are lots of fun.

Great instrument, but you absolutely need a tripod/mount.

I have owned these binos for about 5 years now, and overall I am VERY happy with them. Be sure to get a sturdy tripod, I use the Paragon Plus pro. Mine have given me no problems whatsoever, and are proving to be a wise investment !

Prepared for the weight I selected a suitable tripod which allows me tireless viewing. The construction is quite robust but must be handled with care as all precision instruments.

Great bins however the recommended 'buy these together' which recommends tripod and bracket, do not buy. The bracket is not required and the light duty tripod is a complete waste of time for these heavy binoculars and you run the risk of them falling off the clip on mount.

well, i read the reviews and ignored the ones about terrible collimation...i have the celestron 15X70 and 20x80 pros and they are excellent...so i figured the larger ones would measure up, but not..

Only problem was that when adjusting for distance between eyes, the sheer weight of the binoculars two bodies I was unable to keep them at the distance as nothing seemed to lock them in place. Solved the problem by wedging them apart.
