I just finished this image of Centaurus A, a weird looking and relatively close galaxy best viewed from the Southern Hemisphere. I was especially pleased to resolve hints of a relativistic jet for the first time in the bottom left area which are emissions coming directly from it’s central black hole!

The strategy for this image was to get as much broadband data as possible then only stack the best of that data which worked really well and I explain in more detail here : https://www.youtube.com/watch?v=dkVLdvtRxKY
