  We have produced a cryogenic buffer-gas cooled beam of the diatomic molecular
radical CH (methylidyne). This molecule is of interest for studying cold
chemical reactions and fundamental physics measurements. Its light mass and
ground-state structure make it a promising candidate for electrostatic guiding
and Stark deceleration, which allows for control over its kinetic energy. This
control can facilitate studies of reactions with tuneable collision energies
and trapping for precise spectroscopic studies. Here, we have demonstrated
electrostatic guiding of CH with fluxes up to $10^9$ molecules per steradian
per pulse
