The image is ok, not great but this globular cluster has a particularity, which is to hold a Black Hole at the centre, as it was discovered in 2018. The news can be read at https://esahubble.org/images/potw1804a/, in there it is described how they reach that conclusion, in any case, that makes it a special object to image. It is nice to think that there is a BH there, and I believe is the same sensation with other objects too.

In the picture, in diagonal, from the cluster to the bottom right, almost halfway between the yellow stars, you can see a little galaxy, the ESO 263-29.

Another source of information is at https://www.eso.org/public/australia/news/eso1802/?lang

Regarding the new data set
Scope ASKAR FRA600, Filter UV/IR Cut/Acquired using NINA instead of SharpCap and it is the integration of 30 images of 240" each.
The same OSC and CEM70 mount.
Another source of information of this nice cluster is in http://www.sci-news.com/astronomy/black-hole-globular-cluster-ngc-3201-05640.html

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
