Thor's Helmet (NGC2359)

Kind of an experimental one....

In the beginning I was gathering only Ha and OIII data in order to make an HOO image, but decided to shoot around an hour of RGB for the stars.
During processing , and as I had earlier been working on the M51 hydrogen addtion by continuum subtraction (Adam Block Method on Continuum Subtraction), I thought, maybe its worth trying to apply the same method in this case. First, I created an HOO image and extracted the luminance. Then I added to the red and blue channel the Ha and OIII which were priviously ''continuum subtracted'' and used the channel combination in order to create a new color enhanced RGB image. Both Luminance and RGB images where processed and stretched separetly and then combinded into a single LRGB. A few more curves adjustments and unsharp mask led to this final result.

I dont know, probably, one can reach to the same result by playing with the colors just with the HOO and add the RGB stars in the end. Personally, I found its much more easy to manage the different colors in the nebula by blending different amounts of the the continuum subtracted Ha and OIII into the blue and red channels respectively.

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.
