Abell 5 Planetary Nebula

Imaged on nights of 9/2/2020, 9/3/2020, 9/11/2020, 9/15/2020.

Abell 5 is a Planetary Nebula in the constellation Perseus. It is one of the very dim PNs at magnitude 16.0. Seems much dimmer than that to me. Ha is about 3 to 4 times stronger than the Oiii so that makes the Oiii very hard to separate from the background, but we do have some here. It appears to mostly overlap the areas with Ha so mostly just changes the color toward the blue/green. It is fairly large for a PN with a diameter of only 2.3 arcminutes.

The shape of Abell 5 is a distinct ring with a completely empty center. Very unusual for Abell PNs.

Looking at a pure RBG image there is no evidence of the PN, unless you know exactly where to look there is just a hint of the red ring.

Abell 5 is very rarely imaged, almost no info is found for it on the web.

There is a very tiny central star that may be the star energizing it. Just a guess.

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.
