We develop a generative framework that first learns how modern observations are transformed by an older instrument, uses this transformation to construct paired training data, and then trains a conditional diffusion model to reverse the loss of resolution. A scalable multiscale U-Net and DPM++ sampler generate multiple modern-quality reconstructions from each historical observation.
