Abstract
Several groups, using 1-m to 2-m telescopes on ‘visitor’ arrangements, have employed CCDs to measure stellar trigonometric parallaxes with precisions in the range ±2–5 mas. More intensive observing efforts now routinely achieve sub-mas results with the best obtained to date in the ±0.3–0.5 mas range. Selective dimming of bright target stars using neutral density spots now permit CCD parallax measures of stars as bright as R~4.
