The central part of this interesting-looking nebula is NGC 1491 or LBN 704 to 706 or SH2-206, also called the Fossil Footprint Nebula. It is part of a larger gas cloud in the Perseus arm, at a distance of about 10700 light years. The central part is quite bright and is probably what Herschel discovered. The outer clouds are very faint but still show lovely detail. Just above the nebula there is a faint round smudge of disconnected emission - that is the planetary nebula OU1.

I've selected a somewhat unusual OHS palette, because it gives some more contrast than the more common SHO.

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.
