TS-Optics 20x80 LE Binoculars (TS-Optics, SKU: TS2080LE) are large Porro prism binoculars designed primarily for astronomical observation and detailed long-distance nature viewing. The 80 mm objective lenses provide high light-gathering capability, while 20× magnification makes it possible to resolve fine details of distant objects. The LE – Long Eye Relief – design provides 17 mm eye relief and foldable rubber eyecups, making the binoculars comfortable also for users wearing glasses. The integrated 1/4" tripod adapter enables stable mounting and allows the binoculars to be balanced by sliding them along the central axis.
• large 80 mm objective lenses providing high light-gathering capability, particularly useful for astronomical observation and use in low-light conditions
• fixed 20× magnification allowing detailed observation of distant terrestrial targets and objects in the night sky
• optical system with Porro prisms providing the good sense of image depth characteristic of this design
• prisms made from BAK-4 glass
• broadband multi-coatings on all optical air-to-glass surfaces improving light transmission and image contrast
• 4 mm exit pupil providing efficient use of the large objective lenses at 20× magnification
• true field of view of 3.2°, corresponding to a width of 56 m at a distance of 1000 m
• 17 mm eye relief providing more comfortable observation also for users wearing glasses
• soft foldable rubber eyecups allowing the distance between the eye and eyepiece to be reduced when observing with corrective glasses
• diopter adjustment within a range of ±3 dpt allowing differences between the user's eyes to be compensated
• focusing range from approximately 30 m to infinity
• integrated photo tripod adapter with a 1/4" mount
• ability to slide the binoculars along the central axis of the adapter for correct balance on a tripod
• construction particularly well suited for tripod use, which at 20× magnification helps reduce image shake and make full use of the optical capabilities of the binoculars
• astronomical applications including observation of star fields, star clusters, brighter nebulae, galaxies, and other deep-sky objects accessible to an 80 mm aperture
• suitable for nature, bird, landscape, and other long-distance observations requiring high magnification
• soft carrying case with shoulder strap facilitating storage and transport of the binoculars
