There's a lot going in vdB 9. You've got reflection nebula mixed in with a molecular cloud and it makes for fascinating viewing.

Here's how I processed it:

L:
dynamic crop
deconvolution
histogram transformation
TGV denoise

RGB
channel combination
dynamic crop
background neutralization
color calibration
histogram transformation
TGV denoise (chrominance)
channel combination (adding in L)
starXterminator (generating stars)
LHE
dark structure enhance script
MLT sharpening (very mild)
pixel math stars in
ez star reduction script

I wish we had gathered more lum data. I thought we had enough when I started to process it but would not have minded more. Not that I'm unhappy with this result but there was a limit to how far I felt I could push the noise reduction. I also didn't use PCC because it failed on the photometry half. Strangely it would succeed if I ran SCNR on the linear data first but that seemed fairly destructive. As it turned out the BN/CC combo produced a very similar looking result so I went with that but I do wonder why PCC wouldn't work on this data. One of those mysteries of PixInsight...

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.
