Minkowski 1-18

This PN, also known as PK 231+041, is a planetary nebula located 15000 light years away in the constellation of Puppis at a declination of -14 degrees. It is a magnitude 14 PN which spans 30 arc-seconds in our apparent view. This corresponds to the typical PN diameter of 2 light years. It is located just one-half degree north of M46.

This PN, one of the many interesting PN in the Minkowski catalog, has an interesting interior structure. Like many PN, the outer rim is stronger in HII while the inner section is stronger in OIII. The PN looks like it has had a hole punched out of the center. In addition, in the direction from lower right to upper left, the PN is a bit dimmer and more diffuse. I do not see the progenitor star.

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.
