NGC 1291

This object, also known as NGC 1269, is a face-on double-barred double-ringed spiral galaxy located 36 million light years away in the southern constellation of Eridanus at a declination of -41 degrees. The outer extent of this 9.4 magnitude galaxy spans 10 arc-minutes in our apparent view, which corresponds to a diameter of 110,000 light years.

Instead of arms, this galaxy has multiple rings and bars. The slightly oval outer ring of faint stars is oriented orthogonally to the mid-region bright oval ring. I do not understand the reason for these different ring orientations.

Likewise, the two bars are at slightly different orientations. The small bright central bar is rotated slightly counterclockwise from larger mid-region bar. This larger bar has ansae at each end, mainly extending clockwise from the end of the bar.

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.
