TE-11WZ II 30-70x Wide Zoom Eyepiece 
The 30-70x zoom magnification allows users to easily adjust the range and field of view for objects that are on the move. The lower range of magnification (30x) provides a larger field of view, which is ideal for spotting birds and other wildlife. The higher range of magnification (70x) is perfect for identifying and observing subjects at a distance in detail once you've spotted them.  
Pure Crystal Fluorite
Kowa's Pure Crystal Fluorite lenses exhibit superior performance, even when compared with the most advanced optical glass systems. By eliminating almost all chromatic aberration, the resolution is guaranteed to be clear from edge to edge making the most intricate details visible. Even beginners and first time scope users are able to recognize a discernible difference in both backlit and low-light conditions when compared to other premium optics.
Large 99mm Objective Lens  
A large 99mm pure fluorite crystal objective lens paired with a Kowa XD concave lens produces superior lowlight performance and exquisite detail. This special combination combined with improved optical coatings virtually eliminates chromatic aberration even at high magnification.
Water & Fogproof
The TSN-99A housing is waterproof to JIS Protection Class 7 and filled with dry nitrogen gas to prevent internal fogging for clear viewing in any weather. 
Lightweight Magnesium Alloy Body 
The magnesium alloy body provides the strength and feel of a traditional metal body but at a much lighter weight. 
Anti-Glare Sunshade
The twist-out sunshade increases optical performance by reducing glare on the objective lens. 
Slide the hood away from the body to protect the lens from exposure to rain or to keep direct sunlight from entering the spotting scope. When the object you wish to view is difficult to find, the sight built into the lens hood can be used to find the object.
Quick Focus & Fine Adjustment
The focus knob of the spotting scope has a convenient two-step mechanism that allows for a smooth transition from quick focusing to fine adjustment so you can spot your subject easily and with all the detail Kowa's Crystal Fluorite lenses have to offer.   

When the object is substantially out of focus, use the quick focus knob, to bring the object into focus 3 times faster than when using the fine focus knob. The quick focus knob can focus from 5m to infinity in only two revolutions. The fine focus is convenient for fine focusing and slight adjustments. The minimum focus distance is 5 meters.
Secure Eyepiece Lock
Kowa's mount system of the spotting scope allows the eyepiece to be easily attached and removed. The eyepiece locking mechanism securely mounts the eyepieces to the spotting scope and prevents the zoom eyepiece from accidentally falling out of the eyepiece mount from over-rotation that can occur when zooming.
Rotating Tripod Mount
The rotating tripod mount allows the spotting scope to be set at various angles while attached to the tripod so you'll always have the best view. The body of the spotting scope can be turned by loosening the lock screw counterclockwise and rotating the scope to the desired position. (The rotation range of the spotting scope is 225°.)
Universal Tripod Mounting Screw 
The tripod mount has a removable screw that allows the spotting scope to be attached to either 1/4 and 3/8 inch tripod heads. With the tripod screw inserted the mount can be used on 1/4 inch tripods. Removing the screw allows the scope to be attached to 3/8 inch tripods.
Designed to Digiscope 
The TSN-99 PROMINAR is 100% compatible with the Kowa System accessory range giving you access to Interchangeable eyepieces, accessories and digiscoping adapters for DSLR cameras and smartphones - creating a truly flexible optical tool for many applications.

Even better than my 883

I sold my old 883 to a friend which helped get funding for this new scope. This scope is amazing! My old 883 was amazing, this 99A is just that little bit more. I called and spoke with Coty to order this scope, the purchase was easy, and shipping was FAST. I've decided I need to do some digiscoping, and Coty has helped with those purchases as well.
