Vortex 15-45x65 Viper Straight Spotting Scope

An ideal companion for mid- to long-range shooters and hunters, the straight-through viewing Vortex Optics Viper HD 15-45x65 Spotting Scope delivers bright and sharp high-contrast images with true-to-life colour and crisp clarity at all magnifications, even in low or challenging light conditions.

Image quality is enhanced through the use of anti-reflection fully multi-coated high-density (HD) extra-low dispersion (ED) glass elements in the lens system, and highly reflective dielectric and phase-correcting coatings on the Porro prism system. These optical features work together to maximize light transmission, increase colour fidelity and contrast, and improve clarity and resolution throughout the entire zoom range. The large 65mm objective boosts the spotter's light-gathering capabilities to keep views bright and clear in even the most challenging light conditions and when observing subjects at extreme distances at the maximum magnification.

The large focus collar is easy to manipulate in cold and wet weather, and the the helical focusing system brings subjects into tack-sharp resolution without rotating the lens elements-maintaining precise optical alignment through the entire zoom and focus ranges. This version of the Viper HD is configured with the eyepiece set in-line with the optical tube for straight-through viewing to make acquiring subjects fast and tracking moving subjects easy.

Complementing the optical performance are construction details that will protect the spotter for years. The chassis is made of a lightweight and corrosion-resistant magnesium alloy that is wrapped in a protective rubber armor. The optical tube is argon filled and O-ring sealed to be waterproof and resistant to internal fogging when moving through extreme changes in temperature and environmental conditions. A retractable sunshade prevents lens flare that can spook game and keeps rain and snow off the objective to ensure clear views in less-than-ideal weather. Vortex includes a custom-made stay-on/view-through nylon case that makes setup and breakdown on a tripod fast and easy, while adding another layer of protection and providing the ability to react fast when opportunities present themselves.

Optical Performance

Broad 15-45x fixed zoom eyepiece is ideal for mid- to long-range use

65mm objective lens gathers the light required to use in challenging conditions and to ensure bright views when looking at distant subjects at high power

Traditional Porro prism light path produces clear and bright views without internal light interference

Dielectric prism coatings boost surface reflectivity to greater than 99% for maximum light transmission through the prism, with minimal loss and diffraction

High-density (HD), extra-low dispersion (ED) glass lens elements reduce chromatic and spherical aberrations for increased contrast and improved color rendition and sharpness without distortion across the entire field of view

Proprietary XR anti-reflection fully multi-coated optics increase light transmission for accurate color fidelity and improved contrast and clarity

ArmorTek exterior lens coatings resist scratches and abrasions while allowing oil, dirt, and sap to be cleaned off without leaving smudges or residue

136.5-foot field of view at 1000 yards at 15x; 68-foot field of view at 45x

Use and Handling

Straight-though viewing eyepiece makes finding subjects fast and tracking moving targets easy

Helical focusing mechanism focuses smoothly and quickly without rotating lens elements to maintain optical alignment for tack-sharp views

Large slip-resistant focusing collar is easy to manipulate in cold and wet weather or while wearing gloves

Twist-up rubber eyecup for comfortable use with or without eyewear

Standard 1/4"-20 mount is compatible with a wide variety of quick release (QR) plates, heads, and photo/video/field tripods; mounting shoe is compatible with select QR plates for faster mounting and removal

Rotating tripod collar allows user to precisely adjust the eyepiece position relative to tripod head

Long 19.6-17.8mm eye relief improves viewing comfort with reduced eyestrain

Comfortable 4.3mm exit pupil at 15x will cover most pupils as they open and dilate in low light to keep the whole scene in view without vignetting

Construction Details

Lightweight and durable magnesium-alloy chassis reduces overall weight without sacrificing strength

Protective rubber armoring provides a slip-resistant grip for more secure handling during setup and breakdown

Argon filled and O-ring sealed to be waterproof and resistant to internal fogging when moving through extreme changes in temperature and environmental conditions

Retractable sunshade prevents lens flare that can spook game, reduces glare to maintain contrast and clarity in the view, and keeps rain or snow off of the lens for clearer views in inclement weather

Nylon stay-on/view-through carrying case protects the spotting scope during transport and storage and allows for faster and safer setup and breakdown
