Minkowski 2-55 Planetary Nebula HaO3RGB (Bill McLaughlin)

Minkowski 2-55 Planetary Nebula HaO3RGB

Just over one arcmin in size, M 2-55 was discovered in 1947 by Rudolph Minkowski using photo plates from the 60 inch telescope on Mount Wilson, M2-55 is located in Cepheus at a distance of about 2250 light years. It's bi-polar appearance is typical of many planetary nebula. The central star is hard to make out, probably because it is obscured by dust in the central region of the nebula. There is a recently discovered Ha shock front where the nebula interacts with the interstellar media as is moves toward the lower right (in this image). Too faint to be practically displayed using my f7.4 system, it is located in a arc just outside the nebula at the lower right. It was detected in data from the WISE space telescope and a paper on this can be found here:

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.
