Vixen Telescope ED80Sf Optical Tube Assembly (OTA Only)

The Vixen Optics ED80Sf is an excellent choice for an amateur astronomer wanting a great value in an apochromatic refractor telescope. It travels well, doubling as a great terrestrial spotting scope from stationary positions or for very short hikes.

The ED80Sf offers similar high quality glass and workmanship that Vixen Optics incorporates into their larger instruments. Because of its apochromatic refractor optical design, images are free from chromatic aberration, and it renders high resolution planetary, lunar, and deep-sky visual images. Expect brilliant high-magnification lunar and planetary viewing, as well as good galaxy observing.

The ED80Sf is immediately ready for imaging; you can attach a Vixen T-mount directly to the focuser, but more commonly it is possible to use the included flip mirror with a T-mount on the back.

The ED80Sf comes complete with tube rings and a dovetail mounting plate that joins the tube rings together and attaches to any Vixen mount or to Celestron’s CG-5 or Meade’s LXD75 mounts. Rounding out the package is a 9×50 finderscope with bracket, a Vixen flip mirror system, and a custom-fit aluminum case. All you’ll need to begin observing is a mount and at least one 1.25″ eyepiece.

2″ Crayford focuser accepts 2″ star diagonals & accessories
Flip mirror accepts 1.25″ eyepieces as well as T-mounts for SLR cameras
