This stunning image earned Tim Galvin one of the two top prizes in the 2025/2026 CARTA Image Competition. It is a deep ASKAP radio-continuum image of the Galactic plane, revealing intricate structures in our Milky Way at radio wavelengths, covering 30 square degrees of the sky.

To make this image, Tim modified the WSClean imaging software that is developed by ASTRON such that it supports a feature called "manual scale-dependent masks", by which the user can tune the imaging process very carefully. Tim has contributed his ideas and code to the WSClean repositories such that they are now available to the wider community.
