Hercules Globular Cluster with Pan-STARRS Luminance Insert

The base image is the sum of data collected from 2018, 2020 and 2021. The insert is the color data from the base image overlaid with a luminance image generated from the MAST Pan-STARRS database. The Pan-STARRS image gives a bit more detail to the core of the cluster while maintaining the color authenticity of the base RGC image.

For those interested, here is the link to the MAST database which contains all the data from the public telescopes, including those from the Hubble Space Telescope (https://mast.stsci.edu/portal/Mashup/Clients/Mast/Portal.html). All you have to do is understand how best to work with these data once they are downloaded. It's lots of fun.

The original Hercules image was an APOD March 19, 2020 (https://apod.nasa.gov/apod/ap200319.html).

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.
