Sh2-216 - 2019

This object is a huge planetary nebula located 420 light years away in the constellation of Perseus at a declination of +47 degrees. It is the largest PN in the sky at 1.6 degrees apparent diameter, which corresponds to a diameter of 13 light years. For a perspective on its size, consider that it is over 50 times larger in apparent size than the PN I posted this morning (Abell 78). Although there is a bit of debate in the literature, this PN appears to be the closest PN to earth.

The nebula signal is predominantly Ha, with some OIII towards the top of the image. This nebula is extremely faint and it was a challenge to bring the nebula out of the background. I am not happy about the background noise in the full resolution view but I sacrificed that for the sake being able to see the nebula more clearly.

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.
