The flat-field objective lenses deliver high-contrast views of deep space objects and solar system targets alike - from quick looks at the moon and brighter planets to comet hunting, the Garrett® GT100-45 binocular telescope can take you wherever you want to go. The binocular includes two sets of standard 1.25" oculars, 23mm (57° AFOV) and 13mm (60° AFOV) focal length, yielding 23x and 41x magnification, respectively. Additionally, you always have the ability to expand your magnification range by inserting virtually any 1.25" telescope eyepiece from 40mm down to about 9mm. All air-to-glass surfaces in the air-spaced achromatic objective lenses and the prisms are broadband multi-coated, and the precisely-polished prisms are crafted from high-index BaK4 optical glass. The cast-aluminium binocular body features a durable and attractive glossy white finish and integrated retractable dewshields. Read more
