IC 410 The Tadpoles Nebula in Forax Palette (DocRx)

IC 410 The Tadpoles Nebula in Forax Palette

To this Picture I combined the three monochrome narrowband Images following the Forax Palette mode to blend them in the final image.
Firstly I got to the tone maps of each channel removing the stars from each mono picture. I obtained three starless monocrome images. (picture B)

Then I produced via Pixelmath two intermediate images (picture C);
1) the “o” image that is the OIII mono to the power of inverted pixels (PIP): OIII^~OIII;
2) the “ho” image that is a high contrast image from the formula (Ha*OIII)^~(Ha*OIII); this one is a PIP formula too.

The PIP works as a signal amplifier into the midtones and as a contrast enhancer (picture D).

Then I compose the Forax palette as follows via Pixelmath:

Red channel:o*SII+~o*HA that means “put SII where there is signal in the “o” image and add HA where there is not “o”.
Green channel: ho*HA+~ho*OIII that means “put Ha where you find signal in the “ho” image and add OIII where there is not “ho”
Blue channel: OIII

I then put the stars back in and worked with curves transformation to the final image.

Images were captured in a session I had in 2016 and now I occasionally found these data on an external HDD I thought it was lost. It was a big surprise to me having these data back after five years.

Title: Three Starless Monochrome Images

Description: These are the Three monocrome images I started from.
I removed the stars and started mapping from those three.

Title: The intermediate "o" and "ho" images

Description: 1) the “o” image is the OIII mono to the power of inverted pixels (PIP): OIII^~OIII;
2) the “ho” image that is a high contrast image from the formula (Ha*OIII)^~(Ha*OIII); This is the PIP of the product of Ha times OIII.

Title: The power of inverted pixels

Description: This formula acts as a signal amplifier into the midtones and as a contrast enhancer.
The pixelmath formula is X^~X (X to the power of not X); it is the equivalent of X^(1-X) .

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.
