IC405 HaRGB Mosaic

IC 405 (also known as the Flaming Star Nebula, SH 2-229, or Caldwell 31) is an emission and reflection nebula in the constellation Auriga north of the celestial equator, surrounding the bluish star AE Aurigae. It shines at magnitude +6.0. It surrounds the irregular variable star AE Aurigae and is located near the emission nebula IC 410, the open clusters M38 and M36, and the K-class star Iota Aurigae.
The nebula is about 5 light-years across and lies about 1,500 light-years away from Earth.
It is believed that the proper motion of the central star can be traced back to the Orion's Belt area. (Wikipedia)

A 2-Panel mosaic with the ASI 2600MM, using Ha data from the Chroma 3nm filter, and RGB filter data. Used APP to stack and create the mosaic frames for Ha, and for each RGB channel.

Original version processed in StarTools.
Final version reprocessed in PI, using NBNormalization for the basic color scheme, and further tweaked with masks and curves. GHS, SPCC, RC Astro tools and some sharpening, and final tweak in image editor.

Hope you enjoy.

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.
