Details
The 102 mm Wide View Spotting Scope's 4" aperture provides bright, breath-taking views of both ground and celestial objects. Its fully multi-coated optics perform brilliantly in low light conditions; perfect for squeezing more precious viewing time into those early mornings and late evenings. At 21" in length and 5 lbs. in weight, the 102 mm is lightweight and portable enough for serious field work. Great for bird watching, astronomy and photography as well as nature study.
Two 1¼" eyepieces are included for 20x and 50x magnification. Also included is a 45 degree erect image diagonal and tripod adapter for mounting to any photographic tripod.
Photographers will appreciate the 102's fast (500mm, f/5) optical system. Its classical refractor design with achromatic two-element lens made of crown and flint glass is well suited to both visual and photographic applications.
