I am selling my AT1010 (and other scopes) to pay for a new scope I bought. New style with retractable dew sheild and clamshell ring. This is a blem - a fiber is on the edge of the mirror. Per Vic it does not affect the image. In addition, there is a scratch on the top of the focuser tube. That should be easy to touch up, but it did not bother me enough to fix it. Otherwise the scope is in great condition. $290 plus shipping in CONUS.
