Tom Thumb open cluster (NGC 6451)

Funny name for the cluster, Tom Thumb cluster, it is a nice region, full of contrast of dark and stars clouds in Sagittarius, and there are many clusters there, they are a kind of crystal bags all over around (also close to some from scorpion). Now, Tom must have been a famous guy because there are a number of groceries stores with that name, and maybe other kind of business as well. His fingerprint is right close to the galactic centre... awesome, anyway, it as a nice cluster.
Now, on the image there is another object that was not identified but visible, on the upper right hand side, the open cluster Ruprecht 130, below the Planetary nebula HB5, known as Hubble's double bubble (or PK359-00.1), small cluster but clearly visible.

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.
