NGC 6522, NGC 6528, and Barnard 298

This object is a rare double globular cluster located 25,000 light years away in the constellation of Sagittarius at a declination of -30 degrees. NGC 6522 is the brighter cluster on the left spanning about 60 light years, while NGC 6288 on the right is dimmer and only spans about half of this distance. This is believed to be an optical double - the two clusters are not believed to be interacting.

Both objects are located in Baade's Window, which is an area relatively clear of dust in the direction of the Milky Way galactic bulge. This is why these clusters do not appear reddish as many other objects do in this region. This Astrobin image of mine shows these objects in a wider field of view. The dark nebula slightly above and to the right of NGC 6528 is Barnard 298.

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.
