This is my rendition of the Rosette Nebula presented in the Hubble Palette. Narrowband data has been mapped into the colour channels to create this image. SII filtered light allocated to the Red channel, Ha to Green, and OIII to the Blue channel. My intent was to retain the lovely greens and aqua colouring found in some of the more famous Hubble Palette images. Star colours were created with the narrowband data, no RGB star colours used. I think the resulting colours suit narrowband data images a little better than overlayed RGB stars.

The Rosette Nebula is a large spherical molecular cloud in the Monoceros (the Unicorn) region of the Milky Way. It measures about 130 light-years in diameter and is around 5,000 light-years away. The nebula was created only a few million years ago when a giant molecular cloud collapsed. At its centre, a young open cluster is present, NGC 2244. This star cluster contains several blue-white O-type stars which are some of the hottest and brightest stars in our universe.

As you move outwards away from the centre, darker splotches known as Bok Globulares are present. They are dense clouds of gas and dust, and from our vantage point, they appear as black holes in the cosmos. I think they look very cool.

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.
