Model distributions of interstellar neutral hydrogen and helium in the heliosphere are combined with minimum and maximum activity 3D solar wind fluxes and compositions. Using updated charge-transfer cross-sections we derive maps and spectral properties of the soft X-ray emission as seen from different vantage points and at different solar cycle phases.
