Zeiss Diascope 85 T* FL 65mm Angled Spotting Scope with LotuTec Coating - Carl Zeiss, a name immediately synonymous with uncompromised optical quality, offers the finest spotting scopes available. You can choose from two colors, two viewing angles and two objective sizes.
One of the greatest problems facing sport optics is not only fingerprints, grease and dirt on the glass surface but contamination from water. The incredible Zeiss LotuTec coating acts just like a lotus flower - the drops simply pearl off. With this coating, dirt and finger prints can be easily removed from the smooth surface. In this way, your view will not be interrupted be it in a fog, mist or rain forest.
It is entirely a matter of personal preference which cannot be determined but through experience, but many prefer angled scopes for extended glassing periods as well as when simultaneously sharing a scope amongst multiple viewers. Straight scopes are simple to use, particularly when locating the subject, and shave a bit off of the weight, size and cost. Whether you'll want a 65mm or an 85mm scope will depend on your budget and ability to carry the item. But it is unequivocally true that the 85mm scope will produce a brighter image and more useable real-world magnification.
The 85mm Diascope has a focal length of 504mm. If you're using the Diascope with conventional 1.25" eyepieces by employing the optional #528384 Astronomy Eyepiece Adapter, divide 504mm by the focal length of your eyepiece to determine the effective magnification.
Zeiss' warranty helps retain your purchase's value better than anything else on the market. As long as the paperwork is retained, the lifetime warranty is transferrable from one owner to another!
