NGC 6765 / Minkowski 1-68

This object is a planetary nebula located 5000 light years away in the constellation of Lyra. This is the most strangely shaped planetary nebula that I have ever seen. It is about one arc-minute in diameter to our apparent view which corresponds to a true diameter of 1.5 light years. Based on its unique shape, I am surprised that there are no Hubble or otherwise high quality images available of this object.

According to a 2005 paper by Miranda et al, the bright white lobes are the result of bi-polar jets, the axis of which is oriented perpendicular to our view. The surrounding structure is a ring which is almost edge-on to our view. The fainter structure to the right is a bow-shock. I am not completely in agreement with this assessment because the ring does not look complete to me, with the half towards us appearing to be missing. But I don't have a better suggestion.

The central white blob has a slight reddish tint from the strong HII gas which is present in that region. It is the only area of the nebula where the HII signal is stronger than the OIII signal.

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.
