IsWe 2

This object, IsWe 2 or IW 2, is an extremely faint ancient planetary nebula located 850 light years away in the constellation of Cepheus at a declination of +66 degrees. All PN are faint to some degree, but this one is extremely faint and is one of the faintest objects I have ever imaged. Perhaps that is why this object wasn't discovered until 1987, by Ishida and Weinberger.

This PN is large at 20 arc-minutes in our apparent view, with a diameter of 4 light years. It is one of the largest PN in true size and is almost twice the diameter of the large Helix Nebula (NGC 7293). This PN is suspected to be one of the oldest known PN, on the order of 50,000 years.

The PN is primarily comprised of reddish HII gas. A circular HII shape is seen centered slight above and left of center in this image. A horizontal concentrated band of HII is seen around the orange star, slightly left and below the center of the image. HII is also seen in the background as well, which makes it harder to distinguish the nebula from the background.

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.
