Continuing the narrow band image processing experiment and having a blast. What a creative process! Thanks to many for the inspiration!

Description: Continuing to experiment with NB process flow. Here is my latest. Always learning.

- [ ] Standard calibration for each channel
- [ ] Align images
- [ ] Correct field illumination if necessary
- [ ] Stretch each channel, referencing statistics, to be roughly equivalent in lumination
- [ ] Pixel math with SHO palette
- [ ] SCNR to subtract green
- [ ] Correct magenta script
- [ ] Create a star minize file
- [ ] Create a starnet++ file
- [ ] Stretch starnet++ file using masks when appropriate
- [ ] Evaluate dark structure enhance script
- [ ] Create Photoshop files for starnet++ and star redux images
- [ ] Paste star redux image onto starnet++ image in PS
- [ ] Evaluate star halos in starnet++ image and correct with healing brush. Blink compare with star redux image and correct the major culprits
- [ ] Bring corrected starnet++ image into Camera RAW filter for corrections
- [ ] Evaluate Carboni dark structure enhance and other actions on starnet++ image
- [ ] Work on local contrast adjustments with mask if appropriate.
- [ ] Apply sharpening to starnet++ image
- [ ] Evaluate carbon smoothing on starnet++ image
- [ ] Layer in the star redux image
- [ ] Evaluate for final result

Description: Modified process where color correction is made in Camera Raw vs. using SCNR in PI.

NB Image Processing (Camera Raw color correction)

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.
