IC 405, the Flaming Star Nebula in RGB+Ha

IC 405 is an emission nebula in Auriga. Its brightness is due to radiation from the star AE Aurigae, a runaway star from Orion. Its central structure is complex, with dust clouds and reflection zones. He took the image in seven nights with R, G, B and Ha filters. When reviewing the Ha master I was impressed by the complexity of the central structure and the smoothness of the peripheral areas, interfered with by point stars. My goal was then to preserve these features by uniting the beautiful red and blue coloring of the nebula and the original color of the stars. The step was:
1. Stacked with WBPP of R, G, B and H channels
2. Construction of a pseudoluminance with the R+G+B+H masters, with ImageIntegration, weighted with PSF Signal Weight
3. Independent processing of the pseudoluminance, the RGB color and the H channel, up to the non-linear state of the three images (GSH + Curves)
4. L+RGB fusion with the LRGBCombination process
5. LRGB + H fusion with the NBRGB Combination script (obtaining the LRGB+H* image, color). Ha for the R channel, and a small share of the B image on the B channel.
6. Separation of the stars and the nebula in the three images: LRGB, LRGB+H* and H
7. Obtaining a new pseudoluminance for the nebula, combining 65% of the luminance of NBRGB+H* and 35% of the luminance H (obtaining a luminance of only nebula LRGB+H**)
8. Fusion of LRGB+H*(nebula only, color) with the new nebula only pseudoluminance LRGB+H**, obteining a new color image of the nebula again reinforced in Ha
9. Combination of the luminance of stars from LRGB with the luminance of stars from H (50% + 50%)
10. Application of this new star luminance to the isolated stars of LRGB.
11. Independent adjustments in nebula and stars
12. Fusion nebula + 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.
