Image-to-image astronomical setup under study. Given two imaging systems, Hubble and Webb, characterized by different bands, resolutions, orbits, and time of image acquisition, the problem is to predict the Webb images $\tilde{\mathbf{x}}$ as close as possible to the original Webb images $\mathbf{x}$ from the Hubble ones $\mathbf{z}$ using a learnable model $g_{\theta }$. The considered setup is paired but is characterized by inaccurate geometrical synchronization between the paired images.
