SH2-290 "Abell 31"

Revision title: CROP

Abell 31, according to another cataloging Sh2-290, is a planetary nebula in the constellation of Cancer.
Abell 31 is one of what appears to be the largest planetary nebulae. Due to its angular extent, it now has a low surface brightness of 26.9 Mag/arc-sec². The southern part of the nebula is still surrounded by an arcuate shock zone, while the boundaries of the northern part are very blurred. The latter and the large extent indicate the old age of the planetary nebula, as it is already beginning to mix and dissolve with interstellar matter. (Wikipedia 2023)

The object really isn't bright. You can't see anything on the RGB frames and it's hard to see the PN on the narrowband frames too . Sure, I took pictures when the full moon was approaching,... :-)

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.
