The Swarovski STS-65 HD 65mm Spotting Scope Straight Viewingcombines the legendary image quality and world-class workmanship that nature enthusiasts, tactical professionals, and researchers have come to expect from the brand. The 65mm-objective straight-through viewing configuration is compact, relatively lightweight, and particularly well suited for the hunter, outdoor enthusiast, or birder on the go. This version of the STS-65 is offered here without an eyepiece for those users who already have the optional 25-50x wide-angle or 20-60x zoom eyepieces and want to upgrade their scope body. Extra-low dispersion fluoride glass elements efficiently transmit all wavelengths of visible light, resulting in bright images that are color faithful, crisp, and rich with detail. SWARODUR and SWAROTOP coatings on all lenses and prisms minimize glare while maximizing contrast.

Complementing the optical performance and technologies is a lightweight and durable aluminum-alloy chassis that is wrapped in a protective rubber armor. Its optical tubes are nitrogen filled and O-ring sealed to be dustproof, waterproof and submersible, and resistant to internal fogging when moving through extreme temperature changes or environmental conditions. For mounting, the tripod collar has a 1/4"-20 socket on the bottom of the shoe and rotating collar for precise eyepiece placement relative to the mounting system.

Q: 5. working temperatures ?

A: Buy a high quality fixed eyepieces such as the ones referenced above. Stay away from zoom eyepieces (image quality is not as good, in my humble opinion. Spend more money and get several fixed eyepieces--one that will let you get you fairly close and that will provide a wider field of view, and one that will enable you to get much closer and that will give you a much narrower fov. With this scope, you should have no problem using a high power ep to get up close and see great detail. (Also make sure you get and use a very sturdy tripod.)
