NGC 5248

This object is a spiral galaxy located 60 million light-years away in the constellation of Boötes. It is the only galaxy brighter than magnitude 11.0 in the constellation. The galaxy is about 70,000 ly in diameter and is seen at an angle of about 65 degrees.

This galaxy exceeded my expectations because of the clear detail of the bluish star clusters and pinkish HII regions. In particular, I am fascinated by the 6 bright regions which immediately circle the galaxy core. I thought at first that these were processing artifacts of some sort, but after examining carefully, I think they are really there. I haven't seen this in a galaxy before. They look to be intense star forming regions close to the core.

A number of other smaller interesting galaxies are seen in the image, especially the galaxy to the left which looks like a barred spiral with an outer ring.

The refractors!

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.
