David, If you are using an artificial horizon and making observations with a metal sextant equipped with an optic then sub 1 minute of arc on an intercept should be the norm unless the wind is really blowin
Part of the optics is missing so I view the horizon mirror directly through the telescope mounting ring. I find it difficult to decide when the two small images are touching. Also it is a vernier sextant and I often round the reading to 0.5'.
