Product Description

The ED80Sf 80mm f/7.5 Apochromatic Refractor Telescope Kit from Vixen Optics includes the 80mm compact refractor-style telescope, manual Porta II Alt-Azimuth mount, decorative and stable wood tripod, and an aluminum carrying case for the telescope. The ED80Sf features multicoated Extra-Low Dispersion (ED) lenses to produce an apochromatic optical system that corrects for, and greatly reduces, chromatic and spherical aberrations. This yields views with true color transmission and contrast that are free from distortion across the entire field of view. The rack-and-pinion focuser has an eyepiece holder straight-through from the optical system, and another set 90° to the first. A 9x50 finderscope mounts on the telescope to get you on-target faster than using an eyepiece.

The Porta II Alt-Azimuth mount has a user-friendly friction control system that eliminates axis locks or clutches. When you need to find your subject, simply move the telescope by hand and release it. Dual flexible slow-motion handles are used for fine adjustments and tracking. The handles also reduce vibration during tracking. Rounding out the gear is the Berlebach wood tripod. Made of ash with a clear varnish, it is not only visually appealing; its weight stabilizes the telescope and reduces vibration. Finally, an aluminum hard carrying case protects the telescope during transportation or for storage.
