IC405: The Flaming Star Nebula

To process this image I chose two different workflows, starting with the integrated master. that had DBE applied to remove the background and gradients.

1. The first approach extracted the three channels, rebalanced their respective contribution by using LinearFit and multiplying each channel by a factor that was derived from the camera response curve, finally creating a "HA" and "OIII" image. The result was combined by assigning the images to the RGB channels as follows:

Red -> HA
Blue -> OIII
Green -> ((OIII*HA)^~(OIII*HA))*HA + ~((OIII*HA)^~(OIII*HA))*OIII

This approach alllowed me to emphasise the HA and OIII components of the image, as it was taken using a HA / OIII 7nm dual-band filter.

Further processing of the image followd a standard workflow.

See revision A for the result.

2. The second approach followed the standard workflow without any additonal pre-processing, as described above.

The two resulting images were blended, assigning each image equal weight.

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.
