Abell 16

This planetary nebula is located 4400 light years away in the constellation of Lynx at a declination of +62 degrees. One of the faintest PN that I have imaged in terms of surface brightness, it is a magnitude 16 PN which spans 2.4 arc-minutes in our apparent view. This corresponds to a diameter of 3 light years. This PN is larger than the average PN and is likely older, which explains the diffuse nature of its signal.

Both the OIII and HII are faint signals, with the OIII just slightly brighter. The progenitor star is visible as the tiny blue star just left of center. The offcenter progenitor may be due to slight movement of the PN by the ISM (interstellar medium). Although faint, the nebula has some structure including a slight void at the 11 o'clock position.

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.
