The Hitchhiker parallel camera and studies of faint galaxies

The Hitchhiker camera performs CCD imaging of an off-axis field on a 4 m telescope in parallel with the normal on-axis scientific programmes. Using a dichroic beam splitter it images in two colours simultaneously, obtaining deep images in random fields suitable for survey work. Recent research projects have given particular emphasis to studies of faint galaxies and we present new results on the association of faint blue galaxies with candidate giant galaxies.
