Abell 72

This PN, also known as PK 059+18.1, is a planetary nebula located 3700 light years away in the constellation of Delphinus at a declination of +14 degrees. This nebula spans 3 arc-minutes in our apparent view, which corresponds to a diameter of 3 light years.

Very little has been written about this interesting object. I am fascinated by its filamentary structure, which is a very unusual structure for a planetary nebula. Numerous arcing OIII filaments wind throughout the nebula. The signal is predominantly OIII, with very little Ha. The nebula is oblong, indicating a likely bi-polar PN. The bluish central star is clearly visible. Many small foreground stars are superimposed over the nebula, adding to its dramatic look.

Just below the nebula is the faint white barred spiral galaxy MCG +02-53-005. This galaxy is 200 million light years away, about 50,000 times further away than the nebula. The galaxy diameter is 50,000 light years.

On the right side of the image is the faint galaxy 2MASX J20493655+1335042.

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.
