Thor's Helmet with Planetary Nebula

Thors Helmet is situated in the southern part of the constellation Canis Major, approximately 12.000 light-years away from Earth.
The central star, responsible for illuminating the nebula, is a Wolf-Rayet star named HD 56925. Wolf-Rayet stars are known for their high temperatures and strong stellar winds.
These are massive, evolved stars with very strong stellar winds. They are crucial in shaping the surrounding interstellar medium, giving rise to intricate nebulae like Thors Helmet.

In the top right corner of the image lies PN G228.0-00.4, a Planetary Nebula only about 3' in size.
I was quite surprised to see this, as even deep exposures of this field don't often show it. Small things can can be a highlight, even though the massive Nebula next to it seems dominating.
Enjoy!

Robert

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.
