Minkowski 1-7

This Astrobin Debut Object is a small planetary nebula is located 20,000 light years away in the constellation of Gemini at a declination of +24 degrees. It is a magnitude 13.5 PN which spans 30 arc-seconds in our apparent view. This corresponds to a diameter of 3 light years.

This object is a Minkowski PN. It is also known as PK189+07.1.

I do not understand this structure nor could I find an explanation for it. I have not seen a similar PN in the 200 that I have imaged. The central bright white section has similar OIII and HII signals, with the OIII slightly stronger leading to a bluish glow. Extending beyond this bright section, from 1 o’clock to 7 o’clock, is an oval HII region with a bright rim.

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.
