SO)CELESTRON ULTIMA 80 45 Degree

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.
