Abell 56

This object, also known as PK 037.9-03.4, is a rarely imaged planetary nebula located in the constellation of Aquila at a declination of +3 degrees. I literally could find nothing on this interesting object, which amazes me.

This PN is unusual in both its color and its structure. Few PN are absent of OIII like this one. Also, few PN have such a wide, bright circular ring structure. There is also some bi-polar, or even multi-polar, structure seen in the image. This is indicated by a faint eye-shape, with the long axis oriented from top right to bottom left. This reminds me a bit of the Helix Nebula without the OIII signal. Also, the full resolution view shows an extremely faint, tiny blue star which I believe is the central star.

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.
