Further experiments with PixInsight using Orion Data from 28.12.13. This time investigating debayering the raw subs first rather than letting the default loading do it. Also experimenting with Atrous wavelet noise reduction.

This one used VNG Debayer so each source monochrome DSLR sensel resulted in one RGB image pixel so the sensor resolution is maintained but each pixel is obvious interpolated from several source sensels.

Curves were adjusted in PI with some minor tweeks in LR.

UPDATE: turns out that these test images weren't properly debayered after all. A closer look at the debayered subs showed that they had in fact been debayered twice. It seems like the debayer script in PI is still bound by the DSRL_RAW settings when it loads the raw subs. Hence when the script loaded each NEF file PI handily debayered it before the script got to see it. Solution is to either set the DSLR_RAW format to load the raw file as-is or just not use the debayer script in the first place. I also noted that there are far more debayering options in the main PI format settings that the script offers. By default PI is set to do crude bilinear interpolation when loading raw files but can easily be set to user AHD or create superpixels.

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.
