Here's the SDSS view[0] of this featured[1] section from the Virgo Cluster, in comparison, to put the staggering depth of these exposures in their proper context,

Thanks for the link, I didn't know one can do this with Aladin Lite! But to be fair, if we compare to DESI LS, it looks much less impressive. I.e. all the shells/tidal debris are basically visible in DESI.

Agreed. Here is the link: https://aladin.cds.unistra.fr/AladinLite/?baseImageLayer=CDS...

I agree their results are also great! We do go a bit deeper, but he big difference it the speed we are able to build these images. We are able to image a larger area of the sky in each exposure, and are able to collect more light. This will lets us build images like this one in a few hours of observation, and build up an equivalent image of the entire southern hemisphere.
