NGC 5982, NGC 5981, NGC 5985 Draco Trio

The Draco Trio is a nice geometric, line-of-sight pairing of 3 galaxies. The trio is composed of 2 spiral galaxies and an ellipical. NGC 5981 is the smaller, edge on spiral, residing (counterintuitively) closest to us at a distance of 100 million light years. Next closest is NGC 5985, the face-on spiral at 120 Mly. NGC 5982 is the final galaxy in the trio. It's an interesting elliptical (not often said!) residing at a distance of 130 Mly. What's interesting about NGC 5982 is that it has been found to have many shells of stars (up to 26). These are thought to be caused by mergers with other smaller galaxies. A supermassive black hole resides at the core of NGC 5982.

In this image, at least 5 separate shells are visible in NGC 5982. The edge-on spiral exhibits a dust lane, and the face-on spiral has nice structure, with blue arms and a reddened core. The field is littered with smaller, more distant galaxies. This image was initially captured at the TAAA CAC dark site in southern AZ, but significantly more frames were added at home in western NM.

Description: Raised integration time to 9.75 hours @ f/2.2, and eliminated some lesser subs along the way. Also cropped the image a bit tighter to show off the added detail in the core of the larger face on spiral NGC 5985.

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.
