The largest aperture scope in the Ultima line, the 100 mm Ultima offers more than 50% brighter images than the 80 mm, allowing for better performance in low light conditions. The 100 mm refractor features excellent multi-coated optics packed into a portable and durable refractor design and comes standard with a 22-66x zoom eyepiece. This series was designed to perform well in a range of viewing situations, making it a great all-around optical instrument. You’ll love it for observing nature and long distance spotting and since it is completely waterproof you can feel comfortable using it in extreme weather. The green rubber optical tube allows for subtle observation in any nature environment. Ultima spotters are a great companion for any nature or outdoor enthusiast. Soft carrying case included.

The Maksutov optical design is recognized for being a portable design that is easy to use and has a variety of applications, making it an excellent choice for both terrestrial and astronomical usage. This C90 Mak has excellent optics with razor sharp images over a wide field.
Celestron’s 52268 90mm Maksutov Spotting Scope delivers excellent high power optics in a compact, affordable package. The 52268 package includes a backpack style soft carrying case, an 8×21 erect image finder scope, a 1.25 inch size correct image 45* prism diagonal, and a fully coated 32mm plossl eyepiece for a magnification of 39X.
The Maksutov-Cassegrain design of the C90 uses a combination of mirrors and lenses; this “folded” optical system has a focal length of 1250mm in a body only twelve inches long. The Maksutov design delivers high power views without a trace of the chromatic aberration, also called blue fringing, that can distort high power views in competing refractor style spotting scopes. At 40X magnification where some low cost spotting scopes start to seem fuzzy, the C90 is just getting started. The C90 uses the same 1.25 inch eyepieces used in astronomical telescopes. The standard equipment 32mm plossl eyepiece yields a magnification of 39X, but many other eyepieces can be used to vary the magnification.
The Celestron model 52268 seems very well built, with excellent multi-coatings visible on the front lens. The real beauty of this 90mm Maksutov spotting scope, however, is in the view it offers. When I use an optional 12.5mm eyepiece to look at Jupiter at 100X I can clearly see Jupiter’s major cloud bands as well as its four moons. When I look at the Moon and stars I can easily push the magnification to 200X with an optional 6mm eyepiece. When I look at birds in the backyard, I’m treated to delightful views full of vibrant color and crisp detail. With a close focus distance of only 15 feet, the detail and texture I see is simply amazing.
High magnification viewing requires a solid tripod, of course. Celestron’s Heavy Duty Altazimuth Tripod comes with slow motion controls to allow the scope to be pointed precisely, and I can clamp the dovetail base on my CG5 mount for astronomical use. The other drawback to high magnification viewing is a narrow field of view; high magnification makes it hard to follow moving targets like birds in flight. Overall the Celestron C90 Maksutov Spotting Scope does a fine job as a companion to good pair of binoculars. The C90 also doubles as a portable astronomy scope; it won’t show the flag on the Moon but it will show thousands of craters on the Moon as well as showing the moons of Jupiter and the rings of Saturn. —Jeff Phillips

The most compact model in our Ultima series spotting scopes, the 65 mm refractor features a 45° viewing angle and excellent mulit-coated optics packed into a portable and durable refractor design and it comes standard with an 18-55x zoom eyepiece. This series was designed to perform well in a range of viewing situations, making it a great all-around optical instrument. You’ll love it for observing nature and long distance spotting and since it is completely waterproof you can feel comfortable using it in extreme weather. The green rubber optical tube allows for subtle observation in any nature environment. Ultima spotters are a great companion for any nature or outdoor enthusiast. Soft carrying case included.
The Celestron Ultima 65 Zoom Spotting Scope is the smallest and most affordable scope in Celestron’s popular Ultima series, yet it delivers surprisingly good views. The Ultima 65 is a refractor style spotting scope with multi-layer anti-reflection coatings on the objective lens and on the zoom eyepiece. The Ultima 65 package includes a padded soft case for the scope, a hard case for the removable eyepiece, and a T-thread adapter so you can attach a camera.
The focus ranges from 20 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 1.7 degree field of view at 18X magnification. The 1.7 degree field of view seems a bit narrow, but it is sharp from edge to edge. With my glasses on I need very little focus adjustment while I crank the zoom eyepiece from 18X up to 55X. 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 65 gives me a sharp image either way.
The drawback of the tradition crown and flint achromatic lens used in the Ultima 65 Zoom Spotting Scope is a bit of false color, also known as blue fringing or chromatic aberration. Blue fringing seems well controlled at 18X magnification, but it becomes increasingly noticeable as I zoom up to 55X. Celestron also offers the Ultima 80 which produces a brighter image with a wider field of view, and the Regal 65 F-ED spotting scope which uses exotic ED glass lenses to virtually eliminate blue fringing and produce the sharpest possible high power views.
Celestron’s Ultima 65mm Zoom Spotting Scope combines sharp multi-coated optics with a good quality zoom lens in a compact waterproof package. Top it off with a lifetime “No-Fault” warranty and the Celestron Ultima 65 is simply a great value. —Jeff Phillips
