The Ultima 80-45 features an 80mm objective lens and a 45° viewing angle and offers a step up in aperture from the 65-45, offering 50% brighter images. The 80 mm refractor features excellent multi-coated optics packed into a portable and durable refractor design and it comes standard with a 20-60x 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.

As with all non ED Celestron Ultima refracting spotting scopes (65mm, 80mm, and 100mm), the design of the main objective lens permits the image at all powers to be surprisingly low in chromatic aberration (colour fringing). This one feature alone is remarkable for an achromatic spotting scope at this price, and places the achromatic Ultimas as a benchmark product in this respect.

We feel that at such budget prices, the waterproof 65mm, 80mm and 100mm achromatic spotting scopes easily represent the premier position in their respective class, and out-perform many of the much more expensive spotting scopes. Indeed, the 80mm achromatic Ultima has already been successful in winning a group test in the BBC Sky at Night magazine.
