AB: Spectra of the heliospheric EUV and X-ray emission induced in the charge-transfer collisions of the highly charged solar wind ions with the interstellar gas have been calculated. Cascading photon spectra of individual O$^{q+}$, C$^{q+}$, N$^{q+}$, and Ne$^{q+}$ ions have been constructed using recent data on ion radiative transition probabilities and the state selective population cross sections for charge-transfer collisions of the most abundant heavy solar wind ions with H and He atoms. Emission spectra have been calculated for slow and fast solar winds interacting with the heliospheric H and He gas. Relative intensities of the brightest lines have been predicted. The volume power distribution of the charge-transfer EUV and X-ray emission has been computed for simplified models of the solar winds and the interstellar gas. X-ray images of the heliosphere have been composed for the region of the heliosphere inside 10 AU from the Sun.
