Galactic Thoughts - NGC1909 - Witch Head Nebula in HaLRGB

The Witch Head I had initially planned for November, but the weather in November and December just was not cooperating. I was not expecting to get another chance this season, but this ongoing streak of amazing clear nights allowed to me shoot it!

I tried different methods of combining Hα and L with RGB this time. I ended up boosting the red channel with a continuum-subtracted Hα channel and then combining L with the a*b channels of the boosted (HαR)GB image.

At this time in the season, the Witch is very low so I'm still dealing with quite substantial noise for 10+ hours of integration.

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.
