M53 Showing the Blue stragglers (see description )

Messier 53 is famous for its large number of "blue stragglers".

From the NASA website:

"Messier 53 has surprised astronomers with its unusual number of a type of star called blue stragglers. All the stars in a globular cluster are expected to form around the same time, so they are expected to be roughly the same age. But blue stragglers appear to be brighter and more youthful than they should be. Although their precise nature remains mysterious, these unusual objects are probably formed by close encounters, possibly collisions, between stars in the crowded centers of globular clusters like M53."

Teasing the colors out without using any masks was difficult, but I was afraid that doing local color corrections might create the blue stars I was looking for. All color adjustments were made with curves applied globally to the entire image.

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.
