Ear Nebula

This recently discovered (2005) small faint planetary nebula, designated IPHASX J205013.7 + 465518, is located in the constellation of Cygnus at a declination of +47 degrees. The bright inner region spans 1 arc-minute in our apparent view.

I thought this PN is called the Ear Nebula because the bright inner region looks like an ear, but actually that region is just the ear hole. The larger faint structure is the outer outline of the "ear".

I do not see a progenitor star and, in general, the nebula does not look like a typical PN. But better images from larger telescopes show that the inner region has filaments and bipolar outflow, which is only hinted at in mine.

The nebula is surrounded by a background of faint HII nebulosity.

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.
