Snorkelling between the stars: submarine methods for astronomical observations

Abstract

Trying to reach diffraction-limited astronomical observations from ground-based telescopes is very challenging due to the atmospheric effects contributing to a general blurring of the images. However, astronomy is not the only science facing turbulence problems; obtaining quality images of the undersea world is as ambitious as it is on the sky. One of the solutions contemplated to reach high-resolution images is the use of multiple frames of the same target, known as fusion super-resolution, which is the principle for Lucky Imaging. Here we present the successful result of joining efforts between the undersea and the astronomical research done at the Canary Islands.
