Celestial hemisphere: Northern · Constellation: Sagitta (Sge) · Contains: PK053-03.1

Abell 63

This planetary nebula, also known as PK053.8-3.0, is located 9000 light years away in the constellation of Sagitta at a declination of +17 degrees. It is a magnitude 17 PN which spans 0.7 arc-minutes in our apparent view. This corresponds to a diameter of 1.8 light years.

The HII signal is slightly stronger than the OIII signal throughout the nebula. The shape of this PN is unique, like a broad X superimposed over the normal circular shape. The nebula appears to extend downward towards the small star below it. SIMBAD indicates that the progenitor star is the bright whitish blue star at the center.

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.
