The Rosette Nebula SH2-275

This nebula can be described as a thin, layered disc of stellar gasses with a central hole blown out by the stellar winds from NGC2244, the central cluster of young stars

I like the look of the hole in this image where you can see through the layer of Oiii and the plasma bubble to the Ha on the other side. The Oxygen rich layer appears to be sandwiched on both sides by Ha.

Quick factoids:

5000 ly away 130ly across
Found in the constellation Monoceros
Large star in foreground is Mon12 a k class giant star
Three behind are O type hypergiant stars,
burning at 30-50,000K,
With a mass of around 10,000 suns and around 400,000 brighter than our sun
Together their radiation and solar winds are superheating the bright blue plasma bubble to somewhere around 5 million Kelvin in temp
There are over 2500 new stars forming in the top left quadrant alone
Also known as the Skull nebula
The dark dust clouds in the foreground are known as Bok globules

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.
