We have made multi-wavelength observations of the young planetary nebula NGC 7027. The C-band continuum radio map shown in Figure 1 was obtained from the combination of MERLIN and VLA1 observations (M. Bryce et al., 1996). This map has the highest spatial resolution of any radio images of this object to date and has been compared with the HST archive picture of NGC7027, taken using WFPC2 with a 400 å wide F547N filter, to reveal the differences in the emission at the disparate wavelengths. The two maps, while being superficially different, show emission regions that are similar in size. The contours of radio brightness often coincide with prominent optical features.
