Kowa TSN-774 77mm 3 Straight View Water Proof Spotting Scope, Requires Eyepiece

Features

Kowa Spotting Scope Features

• XD-Lens: This lens has an outstanding optical performance and is easier to work with than fluorite crystal. When an XD lens (eXtra-low-Dispersion-lens) is paired with a concave lens with special dispersion properties, chromatic aberration is almost eliminated
• Compact: The telephoto lens design of using 5 lens elements in 4 groups has successfully shortened the overall length of the scope while keeping a large diameter objective lens without sacrificing optical performance
• Dual focus mechanism (Quick and fine focusing): The well established Kowa focus system has progressed to a new dual focus system. The quick focus, with a large and easy to turn knob, will focus from infinity to five meters in two revolutions
• Eyepiece locking mechanism: Kowa’s standard eyepiece bayonet mount has been passed down to these new spotting scopes with a new attractive feature
• Magnesium alloy body: The magnesium alloy body made by a sophisticated molding process called thixotropic molding has the feel and strength of a traditional metal body with decreased weight when compared to other large-diameter scopes
• Prominar Lens: One of the major causes of deterioration of viewing quality in optics is chromatic aberration. Chromatic aberration occurs due to the dispersion of light and the different wavelengths of light focusing on different positions, resulting in a red or purple fringing around the image
