I added some luminance data taken from the backyard with a ZWO 294MM on a GSO RC8 to an image of the Sombrero I took back in 2020 with the same scope (and a ZWO 1600MM).
Playing in Aladin - I annotated it with the globular clusters brighter than magnitude 20.5. Amazing to me that we can see globular clusters around other galaxies.
Astrobin
link - hovering the mouse over it should show the annotated image.
