We 1-10

This object is a faint, rarely imaged planetary nebula located 1400 light years away in the constellation of Cygnus at a declination of +49 degrees. The nebula spans 3 arc-minutes in our apparent view. This corresponds to a diameter of just over 1 light year, which is typical for a PN.

This nebula was identified by Weinberger through a review of POSS prints. The nebula is the largest of 12 new ones documented in his 1977 paper, New Planetary Nebulae of Low Surface Brightness.

It is interesting to me that the outer edges of the nebula are blurred in some places. I assume that this is due to ISM interaction. Unlike most PN, it is not obvious to me which star in the image, if any, is the progenitor star. A significant amount of HII nebulosity appears in the image.

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.
