The TEC 140 F9.6 Fluorite Doublet is a new high-performance apochromatic refractor telescope crafted by Telescope Engineering Company (TEC). This instrument is designed to deliver exceptional visual observations and astrophotography results, combining premium materials with meticulous engineering.
The telescope is designed to appeal to both visual observers and astrophotographers alike. Its exceptional optics and precise mechanics provide the capability to observe and capture intricate details of planets, the Moon, and deep-sky objects with outstanding clarity.
At the heart of the TEC 140 F9.6 Fluorite Doublet is a 140mm (5.5-inch) aperture doublet lens system with a focal ratio of f/9.6. The use of fluorite glass results in minimal chromatic aberration, delivering crisp and true-color images. The telescope’s design ensures excellent light transmission and contrast, making it ideal for both deep-sky and planetary observations. Its longer focal length provides a narrower field of view, beneficial for high magnification of celestial objects. The fluorite component significantly reduces chromatic aberration, ensuring sharp and color-accurate images across the visible spectrum. The extended focal length contributes to enhanced image contrast and resolution, making it particularly well-suited for planetary and lunar observations.
The telescope’s tube assembly is constructed from lightweight yet robust materials, balancing portability with structural integrity. The precision-machined focuser provides smooth and precise adjustments, accommodating a variety of eyepieces and imaging equipment. The tube’s internal baffling system effectively minimizes stray light, enhancing image contrast.
