The Celestron Ultra 65 18-55x65 manufactures the Ultima line of prismatic spotting scopes in 65mm, 80mm, and 100mm varietals to suit your needs. The larger two can also be had with extra-low dispersion (ED) glass elements, an expensive product that produces a marked improvement in the color fidelity, resolution, and edge delineation of the scope's imagery. All the Ultima lines are mated to an eyepiece and render views that are both right-side-up and laterally correct to the world, making them good for both terrestrial and celestial observing. All Ultimas are waterproof, making them more robust than ever before. Celestron surely is delivering exceptional value.
The Ultimas now offers the choice between 45° angled viewing or straight viewing as you prefer. Most users will prefer angled scopes because they are both simple to use for birds perched high above the viewer as well as easily simultaneously shared among users of differing heights. But some will prefer the straight-through viewing models, for these are much easier to use when hunting down the object of interest in the first place. Straight-viewing models are also usually a bit lighter, brighter, and less expensive. The choice is yours.
The Celestron Ultima series feature a T-mount threading upon the eyepiece barrel, allowing your scope to act as an ultra-telephoto lens upon your SLR camera (digital or film) with just the addition of a camera-specific T-mount adapter.
