Celestron’s popular Ultima 80mm Zoom Spotting Scope offers images that are noticeably brighter and sharper than entry level 60mm spotters. The Ultima 80 is a refractor style spotting scope with an Achromatic objective lens. Excellent light transmission is assured by multi-layer anti-reflection coatings on the objective lens as well as on the zoom eyepiece and the BAK-4 prisms. The multi-coated 80mm objective lens delivers 77% brighter views than a 60mm scope, and the built in zoom lens produces sharp images from 20X all the way up to 60X magnification.

The Ultima 80 features a sleek, waterproof design and includes a padded soft case with zippers on both ends so the scope can be protected even while mounted on a tripod. Including the eyepiece the Ultima 80 measures just over 18 inches long and weighs about 3.6 pounds. The rubber eyecup can be removed to expose a standard “T-thread” for attaching a camera. I like the 45* angled eyepiece because I can use a shorter tripod to support the spotting scope while viewing or while taking pictures with a small camera attached to the eyepiece.

The focus ranges from 27 feet to the horizon with just a few turns of the focus knob. When I fold down the rubber eye cup I can keep my glasses on and see the whole 2 degree field of view at 20X magnification. With my glasses on I need very little focus adjustment while I crank the zoom eyepiece from 20X up to 60X. Sometimes though I like to take my glasses off while observing because the view seems to have just a little more contrast and sharpness. I like the fact that the Ultima 80 gives me a sharp image either way.

The drawback of the tradition crown and flint achromatic lens used in the Ultima 80 Zoom Spotting Scope is a bit of false color, also known as blue fringing or chromatic aberration. Blue fringing seems well controlled at 20X magnification, but it becomes increasingly noticeable as I zoom up to 60X. Celestron also offers the Ultima 80ED and the Regal 80 F-ED spotting scopes which use exotic ED glass lenses to virtually eliminate blue fringing and produce the sharpest possible high power views.

• Twist-up rubber eyecups for a snug fit

Seeing is believing with the Celestron 72021 Ultima DX 10 x 50 waterproof binoculars. The Ultima series has always been one of Celestron's most highly respected line of binoculars. It's hard to believe, but with the newly redesigned Ultima DX Series, outdoor enthusiasts of all stripes will find even greater value.

Combining superb optics, quality construction, and affordability, the Ultima DX series is perfect for the serious bird watcher who demands a binocular that is lightweight and easy to use, or the outdoor enthusiast who relies on rugged durability and resistance to the elements.

The new design elements of the Ultima DX series include a waterproof body, shock-resistant rubber covering, and twist-up eyecups. Ultima DX binoculars provide superb image quality with BAK-4 prisms, fully multi-coated optics, diopter adjustment for sharp focusing, and they are super lightweight for their aperture size. With long eye relief for comfortable viewing and an excellent depth of field that provides a good overview without the need for constant refocusing, all Ultima DX models are excellent for all kinds of long distance viewing. And with large fields of vision, these binoculars are well-suited for astronomical and other low-light observation. It's simply hard to imagine a set of binoculars with these many outstanding features in such a durable yet lightweight design.

The Celestron 72021 features a 10x magnification and an objective lens diameter of 50 millimeters, giving it a 5-millimeter exit pupil. (The exit pupil size -- the diameter of the objective lens divided by the magnification -- determines the amount of light available to your eye. The larger the exit pupil, the brighter the image obtained will be. A three-millimeter exit pupil is generally sufficient for daytime use, five-millimeters is suitable for daytime and twilight, and seven-millimeters is generally necessary for maximum nighttime or astronomy use.) All Ultima DX series models also come with Celestron's No Fault Limited Lifetime Warranty.
