Late for Halloween! SH2-68(Flaming Skull Nebula) in SHO with RGB star color

This is such a fascinating Planetary Nebula, and so eerie!
SH2 68 or The Flaming Skull Nebula is an ancient planetary nebula estimated to be around 45000 years old.
The white dwarf star at the center of the planetary nebula is unusual as it is moving rapidly through space in an area of our galaxy where there is a high concentration of dust and gas. This causes the gas which is blowing off the star to blow back. The diffuse orange emission to the upper right is the result of the planetary nebula's motion through the disk of the galaxy., bluish interior is from energized oxygen atoms. The progenitor star is the very blue star at the center of the bluish gas.

Imaged in SHO narrowband with RGB star color on the PlaneWave CDK 1000 and PlaneWave CDK 700 at Observatorio El Sauce Chile.

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.
