Abell 56 is 206 arc seconds planetary nebula in Aquila. Until recent;y it was thought that Abell 56 only had Ha emissions. That changed recently when Yann Sty's amazing wide field image showed a presence of OIII https://www.astrobin.com/full/6bblb5/F/
Thanks to Marcel Drechsler for bringing this to our attention.
So Sven Eklund and I set about capturing some 10 hours of OIII data. The signal is quite faint, and shows no detailed morphology, other than a ring shape sitting at the heart of Abell 56.

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.
Dismissals 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.
