NGC2244 - Widefield (Olly Barrett)

NGC2244 - Widefield

The Rosette Nebula is a vast emission nebula located about 5,200 light years away. The star forming region lies near a large molecular cloud in the constellation Monoceros, the Unicorn. It is closely associated with the young open star cluster NGC 2244.Also known as the Satellite Cluster, NGC 2244 appears in the centre of the Rosette. The hot young stars of the cluster were formed from the nebula’s material in the last 5 million years. The stars in the Satellite Cluster are responsible for the nebula’s glow. Their radiation ionizes the surrounding clouds of nebulosity, causing them to emit their own light. The nebula naturally glows in the red part of the spectrum because the powerful ultraviolet radiation from the stars strips electrons from the nebula’s hydrogen atoms.
The Rosette Nebula is a very active stellar nursery. It is home to numerous Herbig-Haro objects and Herbig Ae/Be stars, Bok globules, T Tauri stars and clusters of newly formed stars. The dark filaments of dust extending toward the centre of the nebula, sometimes called “elephant trunks,” are shaped by the stellar winds and radiation from hot young stars and electromagnetic forces.

Putting the image together...
I used Ha and Oiii data to make 2 images... First image was HOO then the second image was extracted from that using Bill Blanshan's excellent SHO Normalization Pixelmath script. This gave me a 'classic' HOO paletted image and a 'pseudo' Hubble palette image that were then carefully combined and blended in Photoshop.
Stars were removed before processing then added back at the end. minimal noise reduction was done at the end, before adjusting contrast, saturation and black points.

I really enjoyed imaging this target, it is rich in signal and rewarding to process...

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.
