That’s a neat correlation between a galaxy’s smbh mass and total gc mass - about the same. Also interesting to see that the stars in a cluster don’t have to be related in age or composition at all.
If you don’t know, GCs can be faintly visible with “normal” binoculars. 7x35, 8x42, and 10x50s are popular handheld choices. 20x50s aren’t good at night. The Hercules Cluster is a good one right now so check it out this month when you have clear skies. The Wild Duck cluster is more open but looking towards the core is always a treat. The Lagoon nebula is close to there. Definitely look for the Orion Nebula in his sword sometime this winter. Check star maps/apps if you’re in the southern hemisphere since I’m in the northern and not sure what carries over. Light pollution sucks but at least by me, suburbs more than 10 miles out of an interstate/highway corridor tend to be dark enough. There’s light pollution maps for that too
