The Vixen Optics ED80SF Refractor Telescope with Porta II Mount Head and Wood Tripod features high-grade glass and quality components. Coupled with a medium f/7.5 focal ratio, the ED 80Sf delivers a sharp, color-free image of high contrast. At only 22.4", this is the ultimate grab-n-go APO travel scope. The solid wood tripod and tray add to the stability and use of this package. You will find long observing sessions a pleasure and may want to keep this setup out for quick use.
