From the forest to the mountains to surveying the wonders of the night sky, the 45° angled viewing Vanguard 20-60x80 VEO HD Spotting Scope is designed to provide power and performance to new and experienced users alike for hunting, birding, and general glassing in all environments. Utilizing a massive 80mm objective lens and their Advanced MultiGuard lens coating system boosts its performance in low and challenging conditions while ensuring the views remain bright and clear, even when the magnification is dialed all the way up. Its broad zoom range allows you to scan the landscape for targets at the low 20x with the ability to quickly dial up the power to 60x and make detailed observations of distant subjects. Its combination of magnification and objective lens diameter makes this spotter ideal for beginner astronomers, delivering views of the moon and larger planets, with the ability to survey the night sky for comets or to view constellations. The chassis is made of composite carbon fiber that is protected by black Mitsubishi rubber armor. Carbon fiber is corrosion resistant and lightweight to help offset the weight of the large objective. It is also resistant to thermal expansion, which can cause the optical components to move out of alignment over time. This ensures tack-sharp views for the life of the optic. The chassis is nitrogen filled and O-ring sealed to be waterproof and resistant to internal fogging even in extreme weather and temperature conditions. The angled-viewing configuration sets the eyepiece at a 45° angle to the scope's body, which places your head in a more comfortable viewing position versus straight-through viewing models, and the whole body can be rotated relative to the tripod mount for perfect eyepiece placement. A 1/4"-20 mount makes it compatible with many tripods, quick release plates, and other popular support systems like window mounts.
