This rack & pinion focuser came from my ST-90 refractor, takes 1 ¼” eyepieces and is in good condition.

Total travel of the focuser is ~ 73mm (~2 7/8”), the diameter of the aluminum casting that fits into a telescope tube is ~86.4mm (~3.4 inch). Knobs are ~1.5” in diameter & are plastic. There are a few scratches in the aluminum sleeve that holds the eyepieces (inside scratches are seen in the photo.

I am asking $30; buyer pays actual shipping (probably ~$5 UPS ground CONUS).
