NGC 2244 The Rosette Nebula Mosaic in OIII

The Rosette Nebula is an H II region located near one end of a giant molecular cloud in the Monoceros region of the Milky Way Galaxy.
The cluster and nebula lie at a distance of 5,000 light-years from Earth and measure roughly 130 light years in diameter.
The mass of the nebula is estimated to be around 10,000 solar masses.
Visual Magnitude 9 and apparent dimensions of 1.3 degrees made this a 9 panel mosaic target for my 5 inch refractor.
This is old data from Jan 2018 worked with new Pixinsight tools. Sadly I had to give up on the HA as it was woefully inconsistent but the OIII was ok and shows off the globules nicely.
I think the trick to mosaics is to gather all the channels in shorter sets together to improve consistency.

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.
