I first attempted this galaxy cluster 2 years ago when still dialing in the 24"...
... so I thought I'd try again with things starting to settle down.
Skies were very dark (21.5 SQM) and steady (under 2" FWHM), so color capture was much better than in 2018.
2x drizzle was used to help extract detail in the very smallest galaxies.
"The Hercules Cluster (Abell 2151) is a cluster of about 200 galaxies some 500 million light-years distant in the constellation Hercules. It is rich in spiral galaxies and shows many interacting galaxies. The cluster is part of the larger Hercules Supercluster, which is itself part of the much larger Great Wall super-structure."

If this user has been harassing you, and you shadow-ban them, all their activities on your content will be invisible to everyone except themselves.
They will not know that they have been shadow-banned, and the goal is that eventually they will get bored while having caused no harm, since nobody saw what they posted.
You will remove your shadow-ban on this user, and their comments, messages, etc, will appear again on your content.
Such limitation improves the website as a whole by discouraging people from creating fake accounts to like their own images. Thank you for understanding!
