NGC 6541

This object is a globular star cluster located 20,000 light-years away in the southern constellation of Corona Australis (the Southern Crown). Containing about 150,000 stars, it appears as a nice cluster to me despite its -43 degree declination and low altitude from my backyard site. Southern hemisphere observers will have a much more interesting view of it.

The cluster spans about half of the width of our full moon. The stars of the cluster are easily resolved except within the central core. Many brightly colored blue and orange stars surround the core, with such density that they appear to me to be part of the cluster and not just part of the background sky. The core is very bright and dense.

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.
