I used a Celestron 52250 80mm Ultimate Zoom Spotting Scope to find targets at 100 yards. I have previously purchased and compared three inexpensive 20-60x60 scopes. Chromatic aberration and the overall quality of these scopes were terrible. The brands SVBONY, ENKEEO and AOMEKIE ordered from Revain were tested. Don't waste your time and money with any of them. The Celestron oscilloscope was well packaged and there was only one small dent and scratch in the box. It has no influence on the content. It came with an instruction manual, a small lens cloth and an eyepiece lens in a plastic tube hard case with a separate nylon carrying case. The scope also comes with a nylon carrying case, but it's not padded and doesn't offer significant drop protection. However, you can still use the sight with the cap on by simply unzipping and exposing the lens and eyepiece lens. I love this feature. The visor is waterproof and, according to the instructions, has a BAK4 prism. I could not find any evidence in the user manual or on the Celestron website that this scope was purged with nitrogen or argon. The body of the scope appears to be made out of a metal alloy with a rubberized backing. The eyepiece lens screws onto the body and, as mentioned, can be stored separately in its own hard plastic tube. The eye relief is achieved by the rubber bushing of the eyepiece, which you fold up or down. The magnification ring on the eyepiece is smooth and clear, as is the focus knob. The lens comes with a clip on the lens cap. There is no retractable sunshade on the lens. That's a bummer. I mounted the scope on a camera tripod to test it and immediately noticed that the scope was loaded and tilted forward, in other words, not very well balanced. Therefore, using a stable tripod with this scope is crucial. The images from this scope were excellent considering the price. As with most scopes in this price range, the image quality offers a better view at lower magnifications. Some chromatic aberrations were noticed, but I wouldn't call them outrageous. I find it great as a range spotter and even for light bird watching. No sunshade on the lens, unlined carrying case, tippy design. Hope that helps.
