With a small telescope and conventional techniques we have achieved external radial-velocity errors for bright stars of only ±50 m/s by using an optical fibre feed between telescope and spectrograph. In a search for low-mass companions to solar-type dwarf stars, intrinsic radial-velocity variability was detected in some IAU radial-velocity standard stars but no convincing evidence was found of the presence of low-mass companions to the dwarfs.
