Completion of long-term astrometric plate series yields revised results on the orbits and parallaxes. The subdwarf mu Cassiopeiae seems to be overluminous; the distance of the supergiant epsilon Aurigae is near 600 pc. The unresolved companion in the red dwarf pair BD + 6 deg 398 is of very low mass, and the companion of BD + 67 deg 552 massive but probably underluminous.
