NGC 6752 resides in the Southern sky at a declination of -60 deg. It also lies about 13,000 light-years from us, tagging it as our closest globular cluster. It consists of over 100,000 stars in a sphere about 1.3 light-years in diameter, making it an intermediate density globular cluster.

Globular clusters are spherical concentrations of stars that orbit the galactic center and are dispersed in a broad halo surrounding the galaxy. Globular clusters contain older, redder stars than the galaxy at large, and may represent some of the first stars to be produced in the galaxy. However, the globular clusters’ origins and roles in galactic evolution remain unclear. It does appear clear that globular clusters formed as part of the star formation of the parent galaxy, rather than as a separate galaxy that subsequently underwent captured into their parent galaxies.

Processed by Alex Woronow (2019) using PixInsight, Matlab, AuroraHDR, Topaz. Image was photometrically calibrated in PI, and only saturation was subsequently adjusted. Sharpening of luminosity was done largely in Matlab, with some additional tweaks in Aurora and Topaz.

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.
