NGC 1291 (Barred ring galaxy)

NGC 1291 is a barred ring galaxy approximately 33 million light-years from Earth, seen in the Eridanus constellation. This galaxy is cited as an example of a transitional galaxy between the spiral and lenticular stages.

Lenticular galaxies fit between spiral and elliptical galaxies. They may have central bulges and disks, but no significant spiral arms. They have depleted most of their interstellar material, except possibly for dust in their disks. Although NGC1291 is old (~12 billion years), new stars appear to be forming in its surrounding ring.

NGC1291 is also duplicated as NGC 1269. From Wikipedia: “It was discovered by James Dunlop in 1826 and subsequently entered into the New General Catalogue as NGC 1291 by Johan Ludvig Emil Dreyer. John Herschel then observed the same object in 1836 and entered it into the catalog as NGC 1269 without realizing that it was a duplicate.”

This image was taken using a Meade LX850 10” OTA together with a QHY8 camera. Data for this image was left on the proverbial ‘cutting room floor' for some time. Processing was a challenge given the limited total exposure, as well as technical issues with the acquisition system being used at the time. The image was processed in PixInsight.

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.
