NGC 6497

This object is a small barred spiral double-ring galaxy located 300 million light years away in the constellation of Draco at a declination of +59 degrees. This magnitude 14 galaxy spans 1.5 arc-minutes in our apparent view, which corresponds to a Milky Way like diameter of 120,000 light years.

Despite being an obscure object, this galaxy has been imaged once before on Astrobin, by my friend Gotthard. His version is here.

I imaged this galaxy because I enjoy seeing these unusual barred ring galaxies. This galaxy has two rings – a fairly common mid region ring enclosing the bar, and a more unusual outer ring. This outer ring is actually comprised of 2 overlapping rings with slightly different inclinations. Scientists call this type of outer ring a pseudoring. Pseudorings are more common than true outer rings.

I cropped this object to make the small galaxy more visible. The image field radius is 0.08 degrees.

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.
