Review on 🔭 Celestron Ultima 80 Angled Spotting Scope with 20-60x80mm Zoom Eyepiece - Improved Multi-Coated Optics for Bird Watching, Wildlife Observation, Scenic Views, and Hunting - Waterproof, Fogproof - Comes with a Convenient Soft Carrying Case by Bob Schultz

I have extensive experience with many astronomy and wildlife telescopes; I have expensive and cheap ones and I usually know what to expect when I buy optics. I bought this because I needed a relatively inexpensive scope for hiking and in situations where it could be damaged or stolen. In general, I am dissatisfied with the optical quality. The large lens gives a very bright image which is great which is why I chose it. For the price, it makes a pretty solid impression. However, I only find it usable at the lowest 20x magnification. At this magnification, the images are quite good. However, the reduction in quality occurs very quickly with increasing magnification. It's not uncommon for sharpness to degrade with magnification, but in this range the degradation is dramatic. It also suffers from significant color fringing (chromatic aberration), which also quickly deteriorates as magnification is increased. The focus control is quite coarse, making perfect focus difficult to achieve. Another disappointment is "eye-pupil". This is the distance the eye should be from the eyepiece. It is difficult to see the entire field of view with glasses in this scope. So I recommend if you need a bright image, but only at low magnifications. It is also very poorly suited for lunar or planetary observations. I haven't tested it on the shooting range, maybe it works better there.
