Rosette Nebula in 'Natural Mix' Narrowband

Link: https://www.thinairphotography.com/Astrophotography-Portfolio/Nebulae/i-j2JZKZx/A

I finally got another good crack at this wonderful object. I originally imaged the Rosette many years ago with a OSC astro camera. In that attempt I forgot to turn subframing off and ended up with just an image of the core (that image is somewhere down the page here on my AB page...) This time I did not make that mistake.

The Rosette Nebula is one of the most spectacular deep sky objects in the night sky. The clouds of gas are being stimulated by the radiation from the young stars in the open cluster at the center, NGC 2244. The nebula lies at an estimated distance of about 5,000 light years and spans a distance of roughly 130 light years, not quite fitting completely into the FOV of my imaging telescope used for this capture.

I tried a number of 'mixes' for this, as I was originally not sure of the look I was after. Due to how beautiful this object is even when imaged in LRGB, I finally decided to go for a somewhat natural looking mix, with a pink rose color along the outside and just a hint of blue OIII emission in the core area. I took separate data for RGB stars which were added to accentuate the natural feel of the image. Much of the contribution is from the Hα and OIII data, but I was able to also mix in some of the SII data as well into the final result.

Description: Redid stars to tame saturated blue stars mostly in core. Exchanged a little less saturation of stars overall for more natural looking bright blue stars.

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.
