Rosette Nebula Ha+SHO NGC 2244

The star cluster seen here, in the core of the Rosette Nebula, is called NGC2244. These stars were born from the gasses within this nebula and their fierce radiation and stellar winds continue to shape it.

At an average age of 5 million years, these are mere 'babies'. By comparison, our own sun is over 4.6 billion years old and roughly middle aged. Sadly, many of these O-type stars will never make it that far... lasting just a few million years before ending in a massive supernova. They are among the largest, hottest and least common types of stars that we know of.

The dark blotches are called Bok Globules. These are more dense concentrations of dust and gas; and may be signs of other stars that are about to be born.

This year I was able to combine some new data of this nebula with several hours from last year. At over 24hrs of combined exposure now, this is the sharpest/cleanest version of the Rosette that I've been able to produce. I opted for a modified SHO colour palette for this edit.

Optics were from an 80mm Meade APO refractor. I've combined data from an ASI2600MM and ASI1600MM cameras (using 3nm & 6nm filters respectively).

Hope you enjoy it. Clear skies!

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.
