NGC 6717 - Palomar 9 Globular Cluster

This object is a globular cluster located 20,000 light years away in the southern constellation of Sagittarius. Perhaps because it is hidden in the shadow of the supergiant magnitude 5.0 star Nu2 Sagittarii, this is the first Astrobin entry for this small but pretty cluster.

The cluster consists of mostly bluish stars, with one bright yellow outlier just below the center of the cluster. The cluster is also called Palomar 9, as one of the 15 faint Palomar globular clusters discovered in the 1950’s using photographic plates from the Palomar Observatory Sky Survey (POSS). This cluster is the brightest of all of the Palomar clusters.

The tiny star clump slightly above and to the right of the cluster center has the separate designation of IC 4802.

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.
