Swarovski 65mm Objective Module - 25-60x Product Info Swarovski 65mm 25-60x Objective Module for the modular Swarovski ATX/STX Spotting Scope system. A choice of two eyepieces and three objective modules allows you to customize the perfect spotting scope to suit you. The new ATX / STX telescopes are a completely new generation of telescopes where optical brilliance, user-friendly ergonomic design and modular flexibility combine to create a real revolution in the history of the telescope and set a new benchmark in the industry. For the first time this new range will allow you to change a telescope's performance through the size of the objective lens, allowing you to adapt it exactly to the relevant viewing situation. In the range there are two eyepiece modules and three objective modules. Swarovision Field Flattener This type of image definition has never been achieved before in any other spotting scope, thanks to the field flattener lenses creating a virtually flat image. Even the finest structures are reproduced with razor-sharp clarity right up to the edge with no need for constant refocusing. The result: every detail is instantly captured, producing a perfect image without any distortions. Maximum Contrast A highly innovative optics design combined with fluoride- containing HD lenses minimise interfering colour fringing. This enables maximum colour fidelity and leads to a significant improvement in resolution and contrast. The result: an even more lifelike, contrast-rich image. A Complete View: Large field of view and high zoom range Nothing escapes you. You have your eyes trained on a flock of dunlins, but you catch something at the edge of the picture. A rarity Thanks to their wide field of view, the ATX/STX spotting scopes provide you with a broader, more exciting platform for your viewing experience. In spite of their high zoom range, the new generation of spotting scopes offers a large field of view. This allows you to achieve optimum magnification and detail recognition and also makes it extremely easy for you to search for and find objects, especially if they are in motion. Eye Relief Plus: Large field of view even for spectacle wearers SWAROVISION features a long eye relief and the removable twist-in eyecup is individually adjustable. The result: even spectacle wearers can enjoy a large field of view, not to mention the inimitable edge sharpness. An additional eyecup has been specially developed for spectacle wearers to further increase viewing comfort. Maximum Colour Fidelity: Optimised coatings The enhanced lens and prism coatings (SWARODUR & SWAROTOP) give noticeably better colour reproduction combined with even greater transmission. SWAROCLEAN coatings on the outer lens surfaces create a non-stick effect, making it easier to clean. The result: even more impressive observing experiences, even in low light.
