DESC: The ShortTube's fully coated 80mm achromatic objective lens produces sharp vivid images in a tube only 15.5" long. For astronomy, its modest 400mm (f/5) focal length yields breathtaking wide-field views of the Milky Way (check out the tail of Scorpius!). But it also serves up generous terrestrial vistas as well. And coupled to our sturdy Paragon HD-F2 photo tripod, this package may be all you'll ever want in a daytime-nighttime telescope.
