An Aptonym for the ages

In what was surely fodder for good humored jokes among his peers, astronomer Stewart Sharpless studied galactic nebulae in our galaxy. This image shows two early entries in a catalogue that bears his name:

https://www.adamblockphotos.com/sh2-1.html

The humor is found in the fact that he studied things that are truly "sharpless." These clouds of amorphous gas are faint and diffuse. The bright star near the top left is Delta Scorpii (the southwestern star in the head of Scorpius) and surrounding it are the red glowing clouds of gas that comprise Sh2-7. Near the bottom of the frame is the smaller and brighter cavity of Sh2-1 (the first entry in the catalogue).

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.
